how to answer interview case study questions

9 Types of Questions in Actual Case Interviews

Case interviews at management consulting firms are among the most difficult job interviews, but they are also quite predictable. Once you know the types of questions they ask, preparation is straightforward.

Using years of experience at McKinsey, as well as field reports from thousands of candidates, I’ve crafted a list of 8 common case interview questions, and in this article, I’ll show you how to answer each of them.

Case interview questions – Overview

Types of case interview questions .

Most questions in case interviews belong to one of these 9 types:

1. Framework/issue tree questions 2. Market-sizing and guesstimate questions 3. Valuation questions 4. Brain teaser questions 5. Chart insight questions 6. Value proposition questions 7. Information questions 8. Math problems 9. Solution-finding questions

In this article, we’ll discuss how to answer each question, along with the necessary tips and tricks.

How to answer case interview questions

There are the fo ur basic steps to answer case interview questions:

• Step 1: Clarify any unclear points in the question
• Step 2: Announce approach and ask for time
• Step 3: Draw issue trees to solve the given problem
• Step 4: Pitch your answer and end with a takeaway conclusion.

This general outline may vary depending on each type and each question – for example, brain teasers or information questions need only the last step, while market-sizing and framework questions need all four steps to deliver the perfect answer.

Type 1 – Framework/Issue tree questions

These are on top of the list among popular case interview questions!

If the interviewer asks you to identify factors contributing to a problem or to break down an entity (such as the revenue of a business), he/she is telling you to draw an issue tree.

And to draw a spot-on issue tree, you need to master consulting problem-solving foundations , the MECE principle , and common consulting frameworks . You should check out our other articles on these topics before moving on, because mastering the issue tree is the key to acing every possible case interview.

You also need good business intuition to draw good issue trees, so that’s all the more reason to start reading every day.

Gastronomia – a gourmet restaurant chain has found the turnover rate among its highly-skilled chefs increasing dramatically for the last 3 years; this has led to a noticeable decline in food quality and increased training costs, among other negative effects.

Which factors would you consider when tackling this turnover problem?

Job: Factors from the job itself. Further divided into 3 sub-branches

• Compensations: are the salaries, bonuses, and benefits attractive enough?
• Difficulty: is the job too difficult?
• Nature: is the job too boring, too unengaging, too repetitive…?

Company: Factors from the work environment within the restaurant chain, surrounding the affected jobs. Further divided into 2 sub-branches

• Cultural environment: is the culture at Gastronomia compatible with the chefs?
• Physical environment: is the physical working environment at Gastronomia safe, comfortable, convenient…?

Competitors: Factors from outside the restaurant chain, related to competing job offers. Further divided into 2 sub-branches.

• Inside industry: are other restaurant chains competing with Gastronomia for skilled personnel?
• Outside industry: are there new career options or changes in existing alternatives that draw chefs away from restaurant chains like Gastronomia?

For detailed guides on issue trees, frameworks and their principles, see the articles on Issue Trees , Case Interview Frameworks, and MECE Principle

Type 2 – Market-sizing & guesstimate

These questions go along the lines of “How many trees are there in Central Park?” or “What’s the market size of pick-up trucks in the USA?”

The key to nailing market-sizing and guesstimate questions lies in not the closest results, but the most logical and structured approaches. In fact, the interviewer expects you to follow these four steps:

Step 1: Clarify: Make sure you and the interviewer are on the same page regarding every detail and terminology, so you won’t be answering the wrong question.

Step 2: Break down the problem: Break the item in the question (number of trees in Central Park, market size of pickup trucks) down into smaller, easy-to-estimate pieces.

Step 3: Solve each piece: Estimate each small piece one at a time; each estimation should be backed by facts, figures, or at least observations.

Step 4: Consolidate the pieces: Combine the previous estimations to arrive at a final result; be quick with the math, but don’t rush it if you aren’t confident.

Unless you come up with something about 10 times the reasonable estimate, don’t worry about being “wrong” – the interviewer is unlikely to have a “correct” number in mind, he/she just wants to see your structured mindset.

This question type is so common, we devote a whole article to it, and our Case Interview End-to-End Secrets Program have a separate package on these questions. Check out our comprehensive guide on Market-Sizing & Guesstimate Questions for more details!

Now, here’s a quick example for you to try and get used to this type:

How many smartphones are sold each year, globally?

• Smartphones are phones using exclusively touch-screens.
• “Sold” means sold to the end-consumers. 
• The market size is calculated at present.

Break down the problem:

The global smartphone market can be divided into three segments – developed countries, developing countries, and undeveloped countries.

In each segment, the annual unit sales of smartphones depend on four variables:

• The percentage of “phone-owning age” people among the population
• The percentage of smartphone owners within the “phone-owning age” group.
• The average, annual, per capita “consumption” of smartphones for those owners.

Solve each piece:

• The population is 1.5 billion in developed countries, 5.5 billion in developing countries, and 1 billion in undeveloped countries.
• 80% of the world population is in the “phone-owning age” (Global life expectancy is 70 and everyone older than 15 years counts towards the “phone-owning age” group)
• 100% of the phone-owning age in developed countries will own a smartphone; the figure in developing countries is 75%, while in undeveloped countries it’s 10%.
• The average smartphone user replaces their phone every 3 years – so they “consume” 0.33 phones each year.

=> Estimated global smartphone market: 1.53 billion units per year

=> Actual 2019 global smartphone sales:  1.37 billion units (error margin: 11.7%).

This market-sizing question is solved using a four-step process, which is explained in this article:  Market-Sizing & Guesstimate Questions

Type 3 – Valuation questions

Valuation questions are about estimating the monetary value of a business, and these are very popular in case interviews too!

Valuation questions are a blend of guesstimation/market-sizing, math, and business. They also require basic finance knowledge. There are three ways to estimate the value of a business:

• The NPV Method: take the net cash flow generated by the business, and discount it to the present to account for time value of money. Basically “this company is worth X dollars because it gives me Y dollars over Z years”. This approach works best when the cash flow from the business is positive and stable.
• The Market Method: take one index of the firm (which can be stocks or anything depending on the industry) and multiply it with an industry multiple (the value of one unit of the said index). In other words, “this company is worth AxB dollars because it has A traffic and each traffic is worth B dollars”. This approach works best when the market is transparent and data on similar firms are accessible – usually with major, established industries such as commercial airlines.

In real case interviews, you have to justify your approach then ask the interviewer to give you the necessary data.

Our client wants to sell his organic-food restaurant (called “Cato’s Cabbage Farm”) to retire. How much is his restaurant worth?

(Supposed the interviewer gives you the following data: his current income from the restaurant is $100,000 per year; two other restaurants in the neighborhood – one with 2 times more customers, and another about 0.75 times, have been sold at $1,800,000 and $1,000,000 respectively).

NPV Method: Cato’s Cabbage Farm value = $100,000 / 10% = $1,000,000

Market Method:

Assume the number of customers for Cato’s Cabbage Farm is 1 “customer unit”, then the two neighborhood restaurants get 2 and 0.75 “customer units”.

• Industry multiple: ($1,800,000+$1,000,000) / (2+0.75) = ~$1,018,182
• Cato’s Cabbage Farm value = $1,018,182 x 1 = $1,018,182

Type 4 – Brain teasers

Brain teasers are the least predictable case interview questions – but even these can be learned!

Brain teasers are riddles designed to test unconventional, creative, and logical thinking. A famous example of this is Accenture’s “How do you put a giraffe in a fridge?”.

Although not as popular as before, brain teasers might still appear in consulting interviews; therefore, you should spend some time to prepare.

Most brain teasers can be allocated into these seven types:

• Logical questions are pure logic riddles – there’s no trick, no illusion, no creativity.

In our Case Interview End-to-End Secrets Program , there are +200 brain teasers to help you prepare for these “unpredictable” questions. You can also read our article about Case Interview Brain Teasers for insights on all of these exciting brain teasers, as well as 30 example questions and answers!

How do you put a giraffe in a fridge?

Open the fridge, put the giraffe in, then close the fridge. The question never says how big the fridge or the giraffe is.

For the logic and approach behind each kind of brain teasers, see the article on Brain Teasers.

Type 5 – Chart insight questions

You can’t be a management consultant without mastering the use of charts – the complex, scary-looking real-world charts such as those included in our Case Interview End-to-End Secrets Program.

In management consulting and case interviews, most charts are one (or a combination) of these four basic types:

• Bar charts compare the values of several items at one point in time, or 1-2 items at several time intervals.
• Line charts illustrate time-series data, i.e trends in data over a continuous period.
• Pie charts illustrate proportions, i.e “parts of a whole” analyses.
• Scatter-plots use data points to visualize how two variables relate to each other.

To read these charts and answer chart-insights questions effectively, you must follow a structured, comprehensive process:

You can find a more detailed guide in the Charts section in our article about Consulting Math.

What can you draw from the following chart?

Trends in chart:

• Steady rise in the number of confirmed deaths to about 70-80 per million;
• Both changes started around March 10-11.
• These sudden rises can be explained by events occurring in early-March, and 2.
• If number of cases is kept low, the threat from COVID-19 will remain minimal, considering a mortality rate of only 2%.

Type 6 – Value proposition questions

No business or consulting candidate can succeed without understanding the customers!

Value-proposition questions are not only about correctly identifying customer preferences, but also about analyzing and delivering the answer in a structured fashion. The former relies heavily on business knowledge and intuition, but the latter can be trained methodically and quickly. Personally, I use a “double issue-tree” – essentially a table with customer segments on one axis and proposed values on the other:

For segmenting customers, you can use the following table. However, don’t over-rely on it, since there may be more relevant and insightful question-specific segmentations.

In some cases, clarification is also necessary – both to avoid “answering the wrong question” and to narrow down the range of customers/values you need to cover in the answer.

What will a customer consider when buying a Toyota sedan?

Clarification: A sedan must be branded “Toyota” to be a Toyota sedan – cars with other Toyota-owned brands such as Lexus or Ranz do not count in this question.

Situational Assessment:

Toyota sedans occupy the entry-level and mid-range price segments, so Toyota customers will be more price-conscious than, for example, Lexus customers.

They are also less likely to lean considerably towards one particular factor, so achieving a balance is extremely important.

Functionality factors:

• Comfort: Toyota sedans are mostly for everyday use, so customers should feel comfortable being inside the car.
• Utility: Toyota sedans are used for multiple purposes, so convenience for a wide range of uses is important.

Cost factors

• Purchase price: A car can be an expensive investment while Toyota’s low-to-mid-range customers are more price-conscious, so having a cheap/reasonable price is important.
• Fuel and maintenance: Maintenance and fuel costs over time are likewise inversely related to the decision to buy a Toyota sedan.

Physical factors

• Performance: Customers are usually drivers themselves, who often pay attention to the technical characteristics of the car (speed, acceleration, handling, etc.)
• Visual design: The car should possess the same level of visual appeal as other competitors in the same segment.
• Build quality: Parts of the car should be assembled in a reasonably good manner.

Emotional factors

• Branding: The car should come from a well-known, reputable brand
• Personal preferences: Some customers choose specific cars simply because they “like” the car.

Type 7 – Information questions

In any problem-solving process, information is one of the overarching concerns!

“Information questions” essentially ask if the piece of data you use is obtainable in the first place. In real consulting work, data is not always available – client team members may refuse to cooperate or there’s simply no data on the subject.

There are many kinds of information sources in case interviews/consulting works, but I’ll divide them into primary and secondary sources. Primary sources means you must do the research yourself (or pay someone else to do it for you), such as customer surveys or mystery shoppings. If someone already did that research, and you use their results, it’s called a secondary source – you can get these from the client , the consulting firm you work for, or third-parties such as market research firms or external industry experts.

You can find out more about these sources and how to cite them in real case interviews through this free Prospective Candidate Starter Pack, which contains a glossary of data sources in consulting.

Our Prospective Candidate Starter Pack has a sheet containing all the possible sources of information in case interviews and consulting projects, among numerous other free resources; you can download and use it to answer these questions, by subscribing to our newsletter at the end of this article.

How do you assess your target customer’s preferences for sports cars?

Primary sources: customer survey, customer interviews, Secondary sources: industry reports, client sales reports, third-party expert interview, client expert interview

Type 8 – Math problems

A lot of information in case interviews and consulting work comes in the quantitative form, so you won’t escape Math by joining the consulting industry!

When you have to do the math, perform back-of-the-envelope calculations in a structured fashion, and say out loud what you’re writing. For one thing, it’s safe; for another, you show that you’re careful, organized, and reliable – just like actual consultants.

We have a Math Practice Tool right here! Use it every day, and you’ll be a master of mental calculations in no time flat!

We have a dedicated article on Consulting Math, which you should definitely read.

Type 9 – Solution-finding questions

What’s the point of analyzing a problem, if not to solve it?!

When dealing with solution questions, keep these four points in mind:

• Firstly, in case interviews as well as real consulting projects, solutions must always solve every root cause of a problem, so remember to check if your solutions are relevant and comprehensive.
• Secondly, every solution must be actionable – if your solutions are too expensive, too time-consuming, etc. for the client, they’re useless.
• Thirdly, the interview expects a highly-structured answer; so segment your solutions based on their characteristics (long-term vs short-term is the easiest segmentation)

Last but not least, deliver at least two solutions, preferably three to five. Otherwise, you’ll appear uncreative and lazy to the interviewer’s eyes.

Nailing these questions relies on having excellent business intuition; our Case Interview End-to-End Program has a dedicated Business Intuition package, but you should also train a habit of reading consulting and business articles daily, to sharpen your business mind.

A restaurant that relies solely on on-premise dining found the loss of adjacent parking space (due to termination of contract) harming their revenue. How can they fix that?

The solutions for the restaurant’s parking space problem can be divided into two types:

• Short-term solutions: Find new parking space around the neighborhood, or renegotiate for old parking space (possibly at a higher price).
• Long-term solutions: Introduce takeaway items and off-premise dining.

Reminders on case interview questions

The questions are not clear-cut in candidate-led cases.

There are two extremes in consulting case interview format: interviewer-led (McKinsey) and candidate-led (BCG, Bain).

Interviewer-led cases, on one hand, consist of multiple, clear-cut questions in a larger business case context; the candidate navigates through these questions to arrive at the solutions.

Candidate-led cases, on the other hand, have one big problem, which the candidate must break down into small pieces to identify the root causes and deliver solutions.

This list, therefore, is much more relevant to the interviewer-led format; nonetheless, this guide is still quite beneficial for candidate-led cases, because when solving that big problem, you’ll have to tackle small issues similar to the 8 aforementioned question types.

Mastering the fundamentals is crucial to consistent performance

Although it’s good to study the case interview questions, it is no substitute for mastering the fundamental principles.

Learning the exercises without the basics is like building a house without a foundation. My poor neighbor’s house developed a huge crack right down the center because of its weak foundation, so make sure to build your case interview prep a strong one by knowing the basics first.

Once you’ve mastered the fundamentals, you’ll become much more flexible – this quality is getting increasingly important because case interviews are getting less predictable, and more realistic.

If you haven’t, I advise you to read these articles (especially the first 4) before practicing the question types:

• Case Interview 101
• Issue Tree – The Complete Guide
• MECE Principle
• Case Interview Frameworks
• McKinsey Case Interview – Interviewer-led Format
• BCG & Bain Case Interview – Candidate-led Format

Expect the unexpected

If you study those nine question types, rest assured that you’ve covered the majority of questions in case interviews.

However, these are not all the possible questions you might be given. In actual cases, there are always questions that cannot be categorized neatly. If you do not prepare for these questions, it’s easy to be thrown off-balance.

So, how do you prepare for “the unexpected”?

• Master the basics: Focus your efforts on the basics, once you’ve mastered them it’d be comfortable to move on to higher, more sophisticated levels.
• Business Intuition : You need business intuition for a business-related job, it’s simple as that. Nearly every case concerns business in one way or another – even public sector cases. This is why we also teach business intuition in our Case Interview E2E Secret Program.
• Have mock case interviews : Practice case interviews with ex-consultants will help you get a sense of what might happen or how you might be evaluated in actual cases. Highly experienced coaches from MConsultingPrep will review your performance, giving you the most valuable feedback and actionable tips & techniques.

1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots etc. You might need to pass these before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Two: Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Three: Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Four: Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Five: Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

2.2. where are case interviews in the consulting selection process.

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews. Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start. For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as an interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself!

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.2.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.2.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases. We give some specific advice for online cases in section four. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.2.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.3. Typical case interview format

Before we dive in to the nuts and bolts of case cracking, we should give you a bit more detail on what exactly you’ll be up against on interview day.

Case interviews come in very similar formats across the various consultancies where they are used.

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

2.4. Differences between first and second round interviews

Despite interviews in the first and second round following the same format, second/final round interviews will be significantly more intense. The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.5. Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

2.5.1. Candidate led vs interviewer led case formats

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms.

However, a McKinsey case interview - especially in the first round - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question.

McKinsey’s cases are thus referred to as “interviewer-led”. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially.

2.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions, focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article. However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

2.6. How are things changing in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run. Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and interview blurs. Online cases don’t just reduce the number of candidates to interview, but start directly replacing interviews.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “dumb” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

2.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

3. What do I need to learn to solve cases?

If you’re new to case cracking. You might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking cases is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

3.1. Business fundamentals

Obviously, you are going to need to be familiar with basic business concepts in order to understand the case studies you are given in the first instance.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already.

However, many consultants will be entering from engineering or similar backgrounds and the major consulting firms are hiring more and more PhDs and non-MBA master's graduates from all subjects. These individuals will need to get up to speed on business fundamentals.

Luckily, you don’t need a degree-level understanding of business to crack interview cases, and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Note, though, that learning the very basics of business is the beginning rather than the end of your journey.

Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved.

The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

3.2. How to solve cases like a real consultant

This is the really important bit.

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your interviews.

To address this problem, the MyConsultingCoach team has developed a new, proprietary approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same.

This video has more information on how frameworks can be unreliable and how we address this problem:

Otherwise, let's zoom in to see how our method actually works in more detail:

3.2.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

3.2.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

In practice, structuring a problem with our method means drawing up either an issue tree or an hypothesis tree , depending on how you are trying to address the problem.

These trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues.

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

Join thousands of other candidates cracking cases like pros

3.2.3. lead the analysis.

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level, solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

3.2.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In an interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

3.3. Common case types and the building blocks to solve them

You should tackle each new case on its own merits. However, that’s not to say there aren’t recurring themes that come up fairly reliably in cases - there absolutely are. Business is business and case studies will often feature issues like profitability, competition etc.

Old fashioned framework approaches would have you simply select a defined framework for each kind of case and, in effect, just run the algorithm and wait for a solution to fall out.

We’ve already explained how frameworks can let you down. In this context, too many candidates will fall into the trap of selecting a framework for that case type that simply won’t work for their specific case.

The counterpoint in favour of frameworks, though, is that they are at least fast and prevent you having to start from the ground up with a common kind of case.

Ideally, you should have the best of both worlds - and this is why, in our articles on this site and in our MCC Academy course, we have developed a set of “building bocks” for common case themes.

As they name suggests, building blocks give you modular components for different kinds of case to help build out your own custom structures faster. These then allow you to leverage the symmetries between cases without inheriting the inflexibility of frameworks.

Let’s take a look at five different case types and get a brief idea of how our building block approach helps you with each. You can find more detail on each in the full length articles linked, as well as in the full-length video lessons in our MCC Academy course.

3.3.1. Estimation

Consultants need to push forward to provide definitive recommendations to clients in a timely manner despite typically not having access to full information on a problem. Estimation of important quantities is therefore at the heart of real life consulting work.

Estimation is thus just as fundamental to case cracking.

A case interview might centre on an estimation question, and this might be quite common for a first round interview. However, estimation is also very likely to be a crucial part of pretty well any other kind of case question you receive is likely to include estimation as a crucial component of your analysis.

The kinds of estimation you might be asked to make in a case interview can be very daunting:

• How many bank branches are there in Italy?
• How many cars are sold in Berlin in one year?
• How many people will buy the latest high-tech smartphone on the market?

You might have no idea where to begin with these examples. However, tempting as it might be, your answer cannot ever be a simple guess .

A decent estimation does have a guessed element - though this should really be an educated guess based on some pre-existing knowledge. However, this guessed element is always then combined with a rigorous quantitative method to arrive at a reasonable estimation.

In context of a case interview, it’s important to realise that your interviewer doesn’t really care about the right answer (they don’t need to ask you to find out, after all). What’s important is showing the rational process by which you get to your answer.

A guess that was somehow exactly correct is no good compared to a “wrong” answer that was reached by a very sensible, intelligent process of estimation. In cases, this method will often be a matter of segmentation.

So, where would we start in working out how many cars are sold in Berlin, for example?

The key to estimation case questions is the ability to logically break down the problem into more manageable pieces. In consulting case studies, this will generally mean segmenting a wider population to find a particular target group. For example, starting from the total population of Berlin and narrowing down to the cohort of individuals who will buy a car that year.

There are usually many ways to segment the same starting population, and several different segmentation schemes might be equally valid. However, it is crucial to choose the specific method best suited to the goal in answering the question and allowing you to best leverage the data you have available.

Segmentation must be allied with assumptions in order to arrive at an estimation. These assumptions are the “guessed” element of estimations we mentioned above. Assumptions cannot just be plucked from thin air, but must always be reasonable .

The example below showcases both the segmentation and assumptions made in an estimation of the size of the wedding planning market in London:

Our articles on estimation and the MECE concept are great starting points in getting to grips with consulting estimation. However, the best place to learn how to make estimations is with the dedicated building block video lesson in our MCC Academy course.

Those of you from physics or engineering backgrounds will probably see a lot in common with Fermi questions . We have plenty of estimation cases for you to work through in our free case library. However, Fermi questions are a great way of getting a little extra practice and you can find a lifetime’s supply online.

3.3.2. Profitability

The fundamental goal of any normal business is to maximise profits - nobody is getting up and going to work to lose money. Even Silicon Valley tech start-ups are supposed to be profitable some day!

Profitability problems are thus bread and butter issues for management consultants.

Clients often tell consultants broadly the same story. The business was doing in well in recent years, with strong profits. However, some recent turn of events has upset the status quo and led to concerns around profit levels. Consultants are brought in as businesses are often sufficiently complex that it can be difficult to figure out precisely where and why the company is losing money - let alone how to then reverse the situation and restore healthy profits.

Despite steady growth in customer flow, the Walfort supermarket chain has seen falling profits in the past year. What is the reason for this decline?

Understanding profitability ultimately means understanding the various components that determine a company’s profit. You will need to learn to decompose profit first into revenues and costs (profit being the synthesis of these two factors). Crucially, you then need to segment further, distinguishing different specific revenue streams and separating various fixed and variable costs.

To take an example, just examining the revenue side of profit, the incoming revenues for an insurance firm might be broken down as follows:

Improving profitability will inherently mean increasing revenues and/or decreasing costs. To solve profitability problems, we thus have to understand the ways we can minimise different costs, as well as ways to drive sales and/or optimise pricing to increase revenue. Importantly, you must be able to judge which of these options is best suited to address specific scenarios.

The key to tackling the complex kind of profitability questions given by MBB-level consultancies lies in this proper segmentation.

By contrast, old-fashioned case interview frameworks will simply have you look at aggregate cost and revenue data before recommending generic cost-cutting or revenue-driving measures. However, this will often lead to negative outcomes in more involved cases, making matters worse for the client.

For example, it might well be that a company actually makes a loss when it serves a certain cohort of customers. An airline, for instance, might lose money on economy class customers but make a healthy profit on each business class customer. Attempts to boost revenue by increasing sales across the board might actually reduce profit further by increasing the number of economy class customers. What is required is targeted measures to increase focus on business class and/or mitigate economy class losses.

You can start learning to segment these kinds of cases properly in our article on profitability , whilst the best way to really master profitability questions is our full lesson on the subject in the Building Blocks section of our MCC Academy course.

3.3.3. Pricing

For a company to be profitable at all, it is a pre-requisite that it charges the right price for whatever it sells. However, establishing what price to charge for any one product - or indeed a whole suite of related products - can be a highly complex business.

Consultants are often engaged to negotiate the many variables, with all their complex interdependencies, at play in pricing. Correspondingly, then, pricing is a common theme in case interviews.

• A company launches a new smartphone with a significantly improved camera. How much should they charge?
• A doughnut chain wants to start selling coffee in their shops. How much should they charge per cup?

Clearly, lot of different factors can influence the answers to these questions, and it can be difficult to know where to start. To get a handle on all this complexity, you will need to take a methodical, structured approach.

To really understand pricing, you must begin from fundamentals like the customer’s willingness to pay, the value captured by the company, and the value created for the customer. These basics are shown in the diagram below:

This might seem simple enough, but the exact level at which prices are ultimately set is determined by a whole host of factors, including product availability, market trends, and the need to maintain a competitive position within the market. In particular, if we are changing the price of an existing product, we must consider how the price elasticity of demand might cause sales to fluctuate.

Our four-step method for pricing starts from establishing the customer’s next best alternative, calculating the value added by our own product, and working from there. A summary of this method is given, along with an overview of pricing in general, in our article on the subject . However, the most complete resource is our pricing lesson in the MCC Academy .

3.3.4. Valuation

Valuation is fundamental to any kind of investment. Before allocating capital towards a particular opportunity, an investor must understand precisely what value it holds and how this compares to the other available options.

In short, valuation tells us how much we should be willing to pay to acquire a company or an asset.

There are many ways to value an asset - indeed the finer points are still subject to research in both the academic and private sectors.

Standard ways to assign value include asset-based valuations (notably the Net Asset Value or NAV) and the various multiples so widely used by market traders.

However, in consulting case interviews, you will only usually need to be familiar with Net Present Value (NPV) . This means you need to learn and master the NPV equation:

CF = Cash Flow r = Discount Rate

Whilst this is a pretty simple equation on the face of it, in order to make proper use of it, you will also need to develop a feel for interest/discount rates appropriate to different cases. This will be essential, as you will often have to estimate rational values for these rates for different investments before plugging those values into the NPV equation. Our Case Academy course has more detail here.

Note, though, that NPV is only really half the story.

NPV provides a kind of “absolute” value for an asset. However, the fact is that the worth of any asset will be different for different buyers , depending largely upon what the buyer already owns. In just the same way a spare clutch for a 1975 Ford will be a lot less valuable to a cyclist than to someone restoring the relevant classic car, so a courier business will be more valuable to an online retailer than to an airline.

As such, what we call the Total Enterprise Value (TEV) of an asset is calculated as a function of that asset’s NPV and of the potential cost and revenue synergies resulting from an acquisition. This is shown in the useful structure below:

You can learn more about all aspects of valuation in our article here , as well as in our dedicated video lesson in MCC Academy . These include guides to the kind of interest rates typically required to finance different kinds of investment.

3.3.5. Competitive Interactions

Most of what we’ve discussed so far in terms of case themes and our building block approach to them will all depend upon the prevailing competitive landscape our client exists within. Product prices, profit levels and ultimately valuations can all change over time in response to competition.

What is more, the zero sum dynamics of competitive interactions mean that these things can change quickly .

Companies enjoying near monopolies for years or even decades can quickly see their values go to zero, or near enough, in the face of some innovation by a competitor coming onto the market.

Nokia and Kodak thoroughly dominated the mobile phone and photography markets respectively - until new companies with new products pulled the rug out from under them and led to precipitous collapses.

New market entrants or old competitors with new ideas can throw a company’s whole business model up in the air overnight . Complex decisions about profound changes need to be made yesterday. Firms trying to save themselves will often slash prices in attempts to maintain sales - though this can actually make things worse and result in a corporate death-spiral. Consultants are then frequently called in to help companies survive - with this type of engagement carrying over to inform case interview questions.

You are running an airline and a low-cost competitor, like Ryanair, decides to start operating on your routes. You are rapidly losing customers to their lower fares. How do you respond?

Your eventual solutions to competitive interaction problems will likely need to be novel and unique to the situation. However, the process by which we understand competitive interactions and move towards those solutions is usually very methodical, moving through the limited dimensions in which a company can take action.

The following structure neatly encodes the general options open to responding to new sources of competition:

Of course, we would never suggest that you blanket-apply any strict, inflexible methodology to a whole swathe of case questions – this is precisely the approach that causes so much trouble for candidates using old-fashioned frameworks.

This structure is only a starting point - a shortcut to a bespoke framework specific to the case question in hand. You might well have to alter the details of the structure shown and you will almost certainly have to expand it as you lead the analysis . How you build out your structure and the solutions you provide are necessarily going to depend upon the specific details of the case question.

Thus, in order to deal with competitive interactions, you will need to put in the time to understand how the different strategies available function - as well as how competitors might then react to implementing such strategies. With enough practice, though, soon you won’t be fazed by even the most complex cases of competition between firms.

You can learn more in our article here and in our dedicated video lesson on competitive interaction in the MCC Academy case interview course.

3.4. Mental mathematics

Almost every interview case study will feature some mental mathematics and this is an area where many many candidates let themselves down.

As such, it makes sense to out in the time and make sure you are fully proficient.

Nothing beyond high school level is required, but you probably don’t do much mental arithmetic day to day and will likely need to practice quite a lot to get good enough to reliably perform at pace, under pressure.

We give a high-level overview of what you need to know in our consulting math article , but devote a whole section of our MCC Academy course to a deep dive on consulting math, with plenty of practice material to get you up to scratch.

4. How do I practice for case interviews?

As we said above - case interviews are much like chess. The rules are relatively quick to learn, but you need to practice a lot to get good.

If you’re working through our MCC Academy course, we recommend getting through the core Problem Driven Structure section. After that, you should be practising alongside working through the remainder of the course and beyond. However you do things, you need to get up to speed with the fundamentals before practice is going to do much more than confuse you.

Of course, if you’re enrolled in one of our mentoring programmes , your mentor will let you know precisely when and how you should be scheduling practice, as well as tracking your progress throughout.

4.1. Solo Practice

For solitary preparation, one of the best uses of your time is to work on your mental mathematics . This skill is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

Once you've covered our Building Blocks section, you should then start working through the cases in My Consulting Coach's case bank alongside your work on the course. This is a large library of case interview questions and answers in different formats and difficulties.

To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

4.2. Peer practice

One you have worked through eight cases solo, you should be ready to simulate the interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting.

If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice.

4.3. Professional practice

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even a just few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering the highest quality case interview coaching service available . Each MCC case coach is selected as an MBB consultant with two or more years of experience and strong coaching expertise.

Case interview coaching is hugely beneficial in itself. However, for those who want to genuinely maximise their chances of securing a job offer - and especially for time-poor, busy professionals or hard-pressed students who want to take the guesswork and wasted time out of their case interview prep - we also offer a much more comprehensive service .

With one of our bespoke mentoring programmes , you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

4.4. Practice for online cases

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

5. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

6. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

6.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the interview can then begin.

6.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important. If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

6.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

6.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

6.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

6.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

6.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote interviews are, in effect, around making sure you come across as effectively as you would in person.

6.2.1. Connection

It sounds trivial, but a successful video interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

6.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

6.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your interview actually is. If your interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

6.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom interview, but more so.

7. How we can help

Case Study Interview Questions About the Customer's Business

Knowing the customer's business is an excellent way of setting the tone for a case study.

Use these questions to get some background information about the company and its business goals. This information can be used to introduce the business at the beginning of the case study — plus, future prospects might resonate with their stories and become leads for you.

• Would you give me a quick overview of [company]? This is an opportunity for the client to describe their business in their own words. You'll get useful background information and it's an easy prompt to get the client talking.
• Can you describe your role? This will give you a better idea of the responsibilities they are subject to.
• How do your role and team fit into the company and its goals? Knowing how the team functions to achieve company goals will help you formulate how your solution involves all stakeholders.
• How long has your company been in business? Getting this information will help the reader gauge if pain points are specific to a startup or new company vs. a veteran company.
• How many employees do you have? Another great descriptor for readers to have. They can compare the featured company size with their own.
• Is your company revenue available? If so, what is it? This will give your readers background information on the featured company's gross sales.
• Who is your target customer? Knowing who the target audience is will help you provide a better overview of their market for your case study readers.
• How does our product help your team or company achieve its objectives? This is one of the most important questions because it is the basis of the case study. Get specifics on how your product provided a solution for your client. You want to be able to say "X company implemented our solution and achieved Y. "
• How are our companies aligned (mission, strategy, culture, etc.)? If any attributes of your company's mission or culture appealed to the client, call it out.

How many people are on your team? What are their roles? This will help describe key players within the organization and their impact on the implementation of your solution.

Case Study Interview Questions About the Environment Before the Purchase

A good case study is designed to build trust. Ask clients to describe the tools and processes they used before your product or service. These kinds of case study questions will highlight the business' need they had to fulfill and appeal to future clients.

• What was your team's process prior to using our product? This will give the reader a baseline to compare the results for your company's product.
• Were there any costs associated with the process prior to using our product? Was it more expensive? Was it worth the cost? How did the product affect the client's bottom line? This will be a useful metric to disclose if your company saved the client money or was more cost-efficient.
• What were the major pain points of your process prior to using our product? Describe these obstacles in detail. You want the reader to get as much information on the problem as possible as it sets up the reasoning for why your company's solution was implemented.
• Did our product replace a similar tool or is this the first time your team is using a product like this? Were they using a similar product? If so, having this information may give readers a reason to choose your brand over the competition.
• What other challenges were you and your team experiencing prior to using our product? The more details you can give readers regarding the client's struggles, the better. You want to paint a full picture of the challenges the client faced and how your company resolved them.
• Were there any concerns about how your customers would be impacted by using our product? Getting answers to this question will illustrate to readers the client's concerns about switching to your service. Your readers may have similar concerns and reading how your client worked through this process will be helpful.
• Why didn't you buy our product or a similar product earlier? Have the client describe any hesitations they had using your product. Their concerns may be relatable to potential leads.
• Were there any "dealbreakers" involved in your decision to become a customer? Describing how your company was able to provide a solution that worked within those parameters demonstrates how accommodating your brand is and how you put the customer first. It's also great to illustrate any unique challenges the client had. This better explains their situation to the reader.
• Did you have to make any changes you weren't anticipating once you became a customer? Readers of your case study can learn how switching to your product came with some unexpected changes (good or bad) and how they navigated them. If you helped your client with troubleshooting, ask them to explain that here.

How has your perception of the product changed since you've become a customer? Get the interviewee to describe how your product changed how they do business. This includes how your product accomplished what they previously thought was impossible.

Case Study Interview Questions About the Decision Process

Readers of the case study will be interested in which factors influenced the decision-making process for the client. If they can relate to that process, there's a bigger chance they'll buy your product.

The answers to these questions will help potential customers through their decision-making process.

• How did you hear about our product? If the client chose to work with you based on a recommendation or another positive case study, include that. It will demonstrate that you are a trusted brand with an established reputation for delivering results.
• How long had you been looking for a solution to this problem? This will add to the reader's understanding of how these particular challenges impacted the company before choosing your product.
• Were you comparing alternative solutions? Which ones? This will demonstrate to readers that the client explored other options before choosing your company.
• Would you describe a few of the reasons you decided to buy our product? Ask the interviewee to describe why they chose your product over the competition and any benefits your company offered that made you stand out.
• What were the criteria you used when deciding to buy our product? This will give readers more background insight into the factors that impacted their decision-making process.
• Were there any high-level initiatives or goals that prompted the decision to buy? For example, was this decision motivated by a company-wide vision? Prompt your clients to discuss what lead to the decision to work with you and how you're the obvious choice.
• What was the buying process like? Did you notice anything exceptional or any points of friction? This is an opportunity for the client to comment on how seamless and easy you make the buying process. Get them to describe what went well from start to finish.
• How would you have changed the buying process, if at all? This is an opportunity for you to fine-tune your process to accommodate future buyers.
• Who on your team was involved in the buying process? This will give readers more background on the key players involved from executives to project managers. With this information, readers can see who they may potentially need to involve in the decision-making process on their teams.

Case Study Interview Questions About the Customer's Business Case

Your case study questions should ask about your product or solution's impact on the customer's employees, teams, metrics, and goals. These questions allow the client to praise the value of your service and tell others exactly what benefits they derived from it.

When readers review your product or service's impact on the client, it enforces the belief that the case study is credible.

• How long have you been using our product? This will help readers gauge how long it took to see results and your overall satisfaction with the product or service.
• How many different people at your company use our product? This will help readers gauge how they can adapt the product to their teams if similar in size.
• Are there multiple departments or teams using our product? This will demonstrate how great of an impact your product has made across departments.
• How do you and your team currently use the product? What types of goals or tasks are you using the product to accomplish? Get specifics on how the product actively helps the client achieve their goals.
• If other teams or departments are using our product, do you know how they're using it? With this information, leads can picture how they can use your product across their teams and how it may improve their workflow and metrics.
• What was the most obvious advantage you felt our product offered during the sales process? The interviewee should explain the benefits they've gained from using your product or service. This is important for convincing other leads you are better than the competition.
• Were there any other advantages you discovered after using the product more regularly? Your interviewee may have experienced some additional benefits from using your product. Have them describe in detail what these advantages are and how they've helped the company improve.
• Are there any metrics or KPIs you track with our product? What are they? The more numbers and data the client can provide, the better.
• Were you tracking any metrics prior to using our product? What were they? This will allow readers to get a clear, before-and-after comparison of using your product.
• How has our product impacted your core metrics? This is an opportunity for your clients to drive home how your product assisted them in hitting their metrics and goals.

Case Study Interview Questions About the Buying Team and Internal Advocates

See if there are any individuals at the customer's company who are advocates for your product.

• Are there any additional team members you consider to be advocates for our product? For example, does anyone stick out as a "power user" or product expert on your team? You may want to interview and include these power users in your case study as well. Consider asking them for tips on using your service or product.
• Is there anyone else on your team you think we should talk to? Again, the more people can share their experience using your product, the better.
• Are there any team members who you think might not be the biggest fans of our product or who might need more training? Providing extra support to those struggling with your product may improve their user experience and turn into an opportunity to not only learn about their obstacles but turn them into a product fan
• Would you share some details about how your team implemented our product? Get as much information as possible about the rollout. Hopefully, they'll gush about how seamless the process was.
• Who from your company was involved in implementing our product? This will give readers more insight into who needs to be involved for a successful rollout of their own.
• Were there any internal risks or additional costs involved with implementing our product? If so, how did you address them? This will give insight into the client's process and rollout and this case study question will likely provide tips on what potential leads should be on the lookout for.
• Is there a training process in place for your team's use of our product? If so, what does it look like? If your company provided support and training to the client, have them describe that experience.
• About how long does it take a new team member to get up to speed with our product? This will help leads determine how much time it will take to onboard an employee to your using your product. If a new user can quickly get started seamlessly, it bodes well for you.
• What was your main concern about rolling this product out to your company? Describing their challenges in detail will provide readers with useful insight.

Case Study Interview Questions About Customer Success

Has the customer found success with your product? Ask these questions to learn more.

• By using our product can you measure any reduced costs? If it has, you'll want to emphasize those savings in your case study.
• By using our product can you measure any improvements in productivity or time savings? Any metrics or specific stories your interviewee can provide will help demonstrate the value of your product.
• By using our product can you measure any increases in revenue or growth? Again, say it with numbers and data whenever possible.
• Are you likely to recommend our product to a friend or colleague? Recommendations from existing customers are some of the best marketing you can get.
• How has our product impacted your success? Your team's success? Getting the interviewee to describe how your product played an integral role in solving their challenges will show leads that they can also have success using your product.
• In the beginning, you had XYZ concerns; how do you feel about them now? Let them explain how working with your company eliminated those concerns.
• I noticed your team is currently doing XYZ with our product. Tell me more about how that helps your business. Illustrate to your readers how current customers are using your product to solve additional challenges. It will convey how versatile your product is.
• Have you thought about using our product for a new use case with your team or at your company? The more examples of use cases the client can provide, the better.
• How do you measure the value our product provides? Have the interviewee illustrate what metrics they use to gauge the product's success and how. Data is helpful, but you should go beyond the numbers. Maybe your product improved company morale and how teams work together.

Case Study Interview Questions About Product Feedback

Ask the customer if they'd recommend your product to others. A strong recommendation will help potential clients be more open to purchasing your product.

• How do other companies in this industry solve the problems you had before you purchased our product? This will give you insight into how other companies may be functioning without your product and how you can assist them.
• Have you ever talked about our product to any of your clients or peers? What did you say? This can provide you with more leads and a chance to get a referral.
• Why would you recommend our product to a friend or client? Be sure they pinpoint which features they would highlight in a recommendation.
• Can you think of any use cases your customers might have for our product? Similar industries may have similar issues that need solutions. Your interviewee may be able to provide a use case you haven't come up with.
• What is your advice for other teams or companies who are tackling problems similar to those you had before you purchased our product? This is another opportunity for your client to talk up your product or service.
• Do you know someone in X industry who has similar problems to the ones you had prior to using our product? The client can make an introduction so you can interview them about their experience as well.
• I noticed you work with Company Y. Do you know if they are having any pain points with these processes? This will help you learn how your product has impacted your client's customers and gain insight into what can be improved.
• Does your company participate in any partner or referral programs? Having a strong referral program will help you increase leads and improve customer retention.

Thanks again for your business — working with you to [solve X, launch Y, take advantage of Z opportunity] has been extremely rewarding, and I'm looking forward to more collaboration in the future.

[Name of your company] is building a library of case studies to include on our site. We're looking for successful companies using [product] to solve interesting challenges, and your team immediately came to mind. Are you open to [customer company name] being featured?

It should be a lightweight process — [I, a product marketer] will ask you roughly [10, 15, 20] questions via email or phone about your experience and results. This case study will include a blurb about your company and a link to your homepage (which hopefully will make your SEO team happy!)

In any case, thank you again for the chance to work with you, and I hope you have a great week.

[Your name]

If one of your customers has recently passed along some praise (to you, their account manager, your boss; on an online forum; to another potential customer; etc.), then send them a version of this email:

Hey [customer name],

Thanks for the great feedback — I'm really glad to hear [product] is working well for you and that [customer company name] is getting the results you're looking for.

Case Study Benefits

• Case studies are a form of customer advocacy.
• Case studies provide a joint-promotion opportunity.
• Case studies are easily sharable.
• Case studies build rapport with your customers.
• Case studies are less opinionated than customer reviews.

1. Case studies are a form of customer advocacy.

If you haven't noticed, customers aren't always quick to trust a brand's advertisements and sales strategies.

With every other brand claiming to be the best in the business, it's hard to sort exaggeration from reality.

This is the most important reason why case studies are effective. They are testimonials from your customers of your service. If someone is considering your business, a case study is a much more convincing piece of marketing or sales material than traditional advertising.

2. Case studies provide a joint-promotion opportunity.

Your business isn't the only one that benefits from a case study. Customers participating in case studies benefit, too.

Think about it. Case studies are free advertisements for your customers, not to mention the SEO factor, too. While they're not promoting their products or services, they're still getting the word out about their business. And, the case study highlights how successful their business is — showing interested leads that they're on the up and up.

3. Case studies are easily sharable.

No matter your role on the sales team, case studies are great to have on hand. You can easily share them with leads, prospects, and clients.

Whether you embed them on your website or save them as a PDF, you can simply send a link to share your case study with others. They can share that link with their peers and colleagues, and so on.

Case studies can also be useful during a sales pitch. In sales, timing is everything. If a customer is explaining a problem that was solved and discussed in your case study, you can quickly find the document and share it with them.

4. Case studies build rapport with your customers.

While case studies are very useful, they do require some back and forth with your customers to obtain the exact feedback you're looking for.

Even though time is involved, the good news is this builds rapport with your most loyal customers. You get to know them on a personal level, and they'll become more than just your most valuable clients.

And, the better the rapport you have with them, the more likely they'll be to recommend your business, products, or services to others.

5. Case studies are less opinionated than customer reviews.

Data is the difference between a case study and a review. Customer reviews are typically based on the customer's opinion of your brand. While they might write a glowing review, it's completely subjective and there's rarely empirical evidence supporting their claim.

Case studies, on the other hand, are more data-driven. While they'll still talk about how great your brand is, they support this claim with quantitative data that's relevant to the reader. It's hard to argue with data.

An effective case study must be genuine and credible. Your case study should explain why certain customers are the right fit for your business and how your company can help meet their specific needs. That way, someone in a similar situation can use your case study as a testimonial for why they should choose your business.

Use the case study questions above to create an ideal customer case study questionnaire. By asking your customers the right questions, you can obtain valuable feedback that can be shared with potential leads and convert them into loyal customers.

Case Interviewing Questions

What is a case interview.

The case interview is a scenario modeled after a real business or management problem. Candidates are asked to analyze a problem and provide a solution based on the information given. The majority of cases don’t have a specific answer that you are expected to give; instead, the interviewer is looking for you to demonstrate a problem-solving process that is both analytical and creative.

Who Uses This Style of Interviewing?

Many consulting firms use the case interview as part of their interview process. The case gives candidates a sense of the type of work that consultants do and allows the employer to test the candidate’s ability to analyze, present information, and perform under pressure. However, any employer who is looking for strong problem solving and presentation skills can use case style interviewing.

Skills Evaluated During a Case Interview

• Analytical and reasoning skills
• Ability to organize and present information
• Ability to perform under pressure
• Understanding of basic business principles
• Creativity and resourcefulness

• Business case (most common).  A scenario to gauge the general business knowledge of candidates and how they can logically apply this knowledge. It could focus on different areas such as: profit/loss, organizational structure, and marketing. Example: “An airline finds that, while its revenues are high, the company is still operating at a loss. What is going on?”
• Market-sizing/”Guesstimates.” Estimation questions that require the use of logical deduction and general statistical information to estimate some number or size. Example: “How many gas stations are there in the U.S.?” 
• Brainteasers.  Puzzles or logic questions used to gauge creativity, quantitative skills, and problem-solving skills. Example: “Why are manhole covers round?” 

How to Approach a Case Interview

• Clarify the problem . Ask good questions to clarify and show your understanding of the problem.

2024 Guide: 20+ Essential Data Science Case Study Interview Questions

Case studies are often the most challenging aspect of data science interview processes. They are crafted to resemble a company’s existing or previous projects, assessing a candidate’s ability to tackle prompts, convey their insights, and navigate obstacles.

To excel in data science case study interviews, practice is crucial. It will enable you to develop strategies for approaching case studies, asking the right questions to your interviewer, and providing responses that showcase your skills while adhering to time constraints.

The best way of doing this is by using a framework for answering case studies. For example, you could use the product metrics framework and the A/B testing framework to answer most case studies that come up in data science interviews.

There are four main types of data science case studies:

• Product Case Studies - This type of case study tackles a specific product or feature offering, often tied to the interviewing company. Interviewers are generally looking for a sense of business sense geared towards product metrics.
• Data Analytics Case Study Questions - Data analytics case studies ask you to propose possible metrics in order to investigate an analytics problem. Additionally, you must write a SQL query to pull your proposed metrics, and then perform analysis using the data you queried, just as you would do in the role.
• Modeling and Machine Learning Case Studies - Modeling case studies are more varied and focus on assessing your intuition for building models around business problems.
• Business Case Questions - Similar to product questions, business cases tackle issues or opportunities specific to the organization that is interviewing you. Often, candidates must assess the best option for a certain business plan being proposed, and formulate a process for solving the specific problem.

How Case Study Interviews Are Conducted

Oftentimes as an interviewee, you want to know the setting and format in which to expect the above questions to be asked. Unfortunately, this is company-specific: Some prefer real-time settings, where candidates actively work through a prompt after receiving it, while others offer some period of days (say, a week) before settling in for a presentation of your findings.

It is therefore important to have a system for answering these questions that will accommodate all possible formats, such that you are prepared for any set of circumstances (we provide such a framework below).

Why Are Case Study Questions Asked?

Case studies assess your thought process in answering data science questions. Specifically, interviewers want to see that you have the ability to think on your feet, and to work through real-world problems that likely do not have a right or wrong answer. Real-world case studies that are affecting businesses are not binary; there is no black-and-white, yes-or-no answer. This is why it is important that you can demonstrate decisiveness in your investigations, as well as show your capacity to consider impacts and topics from a variety of angles. Once you are in the role, you will be dealing directly with the ambiguity at the heart of decision-making.

Perhaps most importantly, case interviews assess your ability to effectively communicate your conclusions. On the job, data scientists exchange information across teams and divisions, so a significant part of the interviewer’s focus will be on how you process and explain your answer.

Quick tip: Because case questions in data science interviews tend to be product- and company-focused, it is extremely beneficial to research current projects and developments across different divisions , as these initiatives might end up as the case study topic.

How to Answer Data Science Case Study Questions (The Framework)

There are four main steps to tackling case questions in Data Science interviews, regardless of the type: clarify, make assumptions, gather context, and provide data points and analysis.

Step 1: Clarify

Clarifying is used to gather more information . More often than not, these case studies are designed to be confusing and vague. There will be unorganized data intentionally supplemented with extraneous or omitted information, so it is the candidate’s responsibility to dig deeper, filter out bad information, and fill gaps. Interviewers will be observing how an applicant asks questions and reach their solution.

For example, with a product question, you might take into consideration:

• What is the product?
• How does the product work?
• How does the product align with the business itself?

Step 2: Make Assumptions

When you have made sure that you have evaluated and understand the dataset, start investigating and discarding possible hypotheses. Developing insights on the product at this stage complements your ability to glean information from the dataset, and the exploration of your ideas is paramount to forming a successful hypothesis. You should be communicating your hypotheses with the interviewer, such that they can provide clarifying remarks on how the business views the product, and to help you discard unworkable lines of inquiry. If we continue to think about a product question, some important questions to evaluate and draw conclusions from include:

• Who uses the product? Why?
• What are the goals of the product?
• How does the product interact with other services or goods the company offers?

The goal of this is to reduce the scope of the problem at hand, and ask the interviewer questions upfront that allow you to tackle the meat of the problem instead of focusing on less consequential edge cases.

Step 3: Propose a Solution

Now that a hypothesis is formed that has incorporated the dataset and an understanding of the business-related context, it is time to apply that knowledge in forming a solution. Remember, the hypothesis is simply a refined version of the problem that uses the data on hand as its basis to being solved. The solution you create can target this narrow problem, and you can have full faith that it is addressing the core of the case study question.

Keep in mind that there isn’t a single expected solution, and as such, there is a certain freedom here to determine the exact path for investigation.

Step 4: Provide Data Points and Analysis

Finally, providing data points and analysis in support of your solution involves choosing and prioritizing a main metric. As with all prior factors, this step must be tied back to the hypothesis and the main goal of the problem. From that foundation, it is important to trace through and analyze different examples– from the main metric–in order to validate the hypothesis.

Quick tip: Every case question tends to have multiple solutions. Therefore, you should absolutely consider and communicate any potential trade-offs of your chosen method. Be sure you are communicating the pros and cons of your approach.

Note: In some special cases, solutions will also be assessed on the ability to convey information in layman’s terms. Regardless of the structure, applicants should always be prepared to solve through the framework outlined above in order to answer the prompt.

The Role of Effective Communication

There have been multiple articles and discussions conducted by interviewers behind the Data Science Case Study portion, and they all boil down success in case studies to one main factor: effective communication.

All the analysis in the world will not help if interviewees cannot verbally work through and highlight their thought process within the case study. Again, interviewers are keyed at this stage of the hiring process to look for well-developed “soft-skills” and problem-solving capabilities. Demonstrating those traits is key to succeeding in this round.

To this end, the best advice possible would be to practice actively going through example case studies, such as those available in the Interview Query questions bank . Exploring different topics with a friend in an interview-like setting with cold recall (no Googling in between!) will be uncomfortable and awkward, but it will also help reveal weaknesses in fleshing out the investigation.

Don’t worry if the first few times are terrible! Developing a rhythm will help with gaining self-confidence as you become better at assessing and learning through these sessions.

Product Case Study Questions

With product data science case questions , the interviewer wants to get an idea of your product sense intuition. Specifically, these questions assess your ability to identify which metrics should be proposed in order to understand a product.

1. How would you measure the success of private stories on Instagram, where only certain close friends can see the story?

Start by answering: What is the goal of the private story feature on Instagram? You can’t evaluate “success” without knowing what the initial objective of the product was, to begin with.

One specific goal of this feature would be to drive engagement. A private story could potentially increase interactions between users, and grow awareness of the feature.

Now, what types of metrics might you propose to assess user engagement? For a high-level overview, we could look at:

• Average stories per user per day
• Average Close Friends stories per user per day

However, we would also want to further bucket our users to see the effect that Close Friends stories have on user engagement. By bucketing users by age, date joined, or another metric, we could see how engagement is affected within certain populations, giving us insight on success that could be lost if looking at the overall population.

2. How would you measure the success of acquiring new users through a 30-day free trial at Netflix?

More context: Netflix is offering a promotion where users can enroll in a 30-day free trial. After 30 days, customers will automatically be charged based on their selected package. How would you measure acquisition success, and what metrics would you propose to measure the success of the free trial?

One way we can frame the concept specifically to this problem is to think about controllable inputs, external drivers, and then the observable output . Start with the major goals of Netflix:

• Acquiring new users to their subscription plan.
• Decreasing churn and increasing retention.

Looking at acquisition output metrics specifically, there are several top-level stats that we can look at, including:

• Conversion rate percentage
• Cost per free trial acquisition
• Daily conversion rate

With these conversion metrics, we would also want to bucket users by cohort. This would help us see the percentage of free users who were acquired, as well as retention by cohort.

3. How would you measure the success of Facebook Groups?

Start by considering the key function of Facebook Groups . You could say that Groups are a way for users to connect with other users through a shared interest or real-life relationship. Therefore, the user’s goal is to experience a sense of community, which will also drive our business goal of increasing user engagement.

What general engagement metrics can we associate with this value? An objective metric like Groups monthly active users would help us see if Facebook Groups user base is increasing or decreasing. Plus, we could monitor metrics like posting, commenting, and sharing rates.

There are other products that Groups impact, however, specifically the Newsfeed. We need to consider Newsfeed quality and examine if updates from Groups clog up the content pipeline and if users prioritize those updates over other Newsfeed items. This evaluation will give us a better sense of if Groups actually contribute to higher engagement levels.

4. How would you analyze the effectiveness of a new LinkedIn chat feature that shows a “green dot” for active users?

Note: Given engineering constraints, the new feature is impossible to A/B test before release. When you approach case study questions, remember always to clarify any vague terms. In this case, “effectiveness” is very vague. To help you define that term, you would want first to consider what the goal is of adding a green dot to LinkedIn chat.

5. How would you diagnose why weekly active users are up 5%, but email notification open rates are down 2%?

What assumptions can you make about the relationship between weekly active users and email open rates? With a case question like this, you would want to first answer that line of inquiry before proceeding.

Hint: Open rate can decrease when its numerator decreases (fewer people open emails) or its denominator increases (more emails are sent overall). Taking these two factors into account, what are some hypotheses we can make about our decrease in the open rate compared to our increase in weekly active users?

Data Analytics Case Study Questions

Data analytics case studies ask you to dive into analytics problems. Typically these questions ask you to examine metrics trade-offs or investigate changes in metrics. In addition to proposing metrics, you also have to write SQL queries to generate the metrics, which is why they are sometimes referred to as SQL case study questions .

6. Using the provided data, generate some specific recommendations on how DoorDash can improve.

In this DoorDash analytics case study take-home question you are provided with the following dataset:

• Customer order time
• Restaurant order time
• Driver arrives at restaurant time
• Order delivered time
• Customer ID
• Amount of discount
• Amount of tip

With a dataset like this, there are numerous recommendations you can make. A good place to start is by thinking about the DoorDash marketplace, which includes drivers, riders and merchants. How could you analyze the data to increase revenue, driver/user retention and engagement in that marketplace?

7. After implementing a notification change, the total number of unsubscribes increases. Write a SQL query to show how unsubscribes are affecting login rates over time.

This is a Twitter data science interview question , and let’s say you implemented this new feature using an A/B test. You are provided with two tables: events (which includes login, nologin and unsubscribe ) and variants (which includes control or variant ).

We are tasked with comparing multiple different variables at play here. There is the new notification system, along with its effect of creating more unsubscribes. We can also see how login rates compare for unsubscribes for each bucket of the A/B test.

Given that we want to measure two different changes, we know we have to use GROUP BY for the two variables: date and bucket variant. What comes next?

8. Write a query to disprove the hypothesis: Data scientists who switch jobs more often end up getting promoted faster.

More context: You are provided with a table of user experiences representing each person’s past work experiences and timelines.

This question requires a bit of creative problem-solving to understand how we can prove or disprove the hypothesis. The hypothesis is that a data scientist that ends up switching jobs more often gets promoted faster.

Therefore, in analyzing this dataset, we can prove this hypothesis by separating the data scientists into specific segments on how often they jump in their careers.

For example, if we looked at the number of job switches for data scientists that have been in their field for five years, we could prove the hypothesis that the number of data science managers increased as the number of career jumps also rose.

• Never switched jobs: 10% are managers
• Switched jobs once: 20% are managers
• Switched jobs twice: 30% are managers
• Switched jobs three times: 40% are managers

9. Write a SQL query to investigate the hypothesis: Click-through rate is dependent on search result rating.

More context: You are given a table with search results on Facebook, which includes query (search term), position (the search position), and rating (human rating from 1 to 5). Each row represents a single search and includes a column has_clicked that represents whether a user clicked or not.

This question requires us to formulaically do two things: create a metric that can analyze a problem that we face and then actually compute that metric.

Think about the data we want to display to prove or disprove the hypothesis. Our output metric is CTR (clickthrough rate). If CTR is high when search result ratings are high and CTR is low when the search result ratings are low, then our hypothesis is proven. However, if the opposite is true, CTR is low when the search result ratings are high, or there is no proven correlation between the two, then our hypothesis is not proven.

With that structure in mind, we can then look at the results split into different search rating buckets. If we measure the CTR for queries that all have results rated at 1 and then measure CTR for queries that have results rated at lower than 2, etc., we can measure to see if the increase in rating is correlated with an increase in CTR.

10. How would you help a supermarket chain determine which product categories should be prioritized in their inventory restructuring efforts?

You’re working as a Data Scientist in a local grocery chain’s data science team. The business team has decided to allocate store floor space by product category (e.g., electronics, sports and travel, food and beverages). Help the team understand which product categories to prioritize as well as answering questions such as how customer demographics affect sales, and how each city’s sales per product category differs.

Modeling and Machine Learning Case Questions

Machine learning case questions assess your ability to build models to solve business problems. These questions can range from applying machine learning to solve a specific case scenario to assessing the validity of a hypothetical existing model . The modeling case study requires a candidate to evaluate and explain any certain part of the model building process.

11. Describe how you would build a model to predict Uber ETAs after a rider requests a ride.

Common machine learning case study problems like this are designed to explain how you would build a model. Many times this can be scoped down to specific parts of the model building process. Examining the example above, we could break it up into:

How would you evaluate the predictions of an Uber ETA model?

What features would you use to predict the Uber ETA for ride requests?

Our recommended framework breaks down a modeling and machine learning case study to individual steps in order to tackle each one thoroughly. In each full modeling case study, you will want to go over:

• Data processing
• Feature Selection
• Model Selection
• Cross Validation
• Evaluation Metrics
• Testing and Roll Out

12. How would you build a model that sends bank customers a text message when fraudulent transactions are detected?

Additionally, the customer can approve or deny the transaction via text response.

Let’s start out by understanding what kind of model would need to be built. We know that since we are working with fraud, there has to be a case where either a fraudulent transaction is or is not present .

Hint: This problem is a binary classification problem. Given the problem scenario, what considerations do we have to think about when first building this model? What would the bank fraud data look like?

13. How would you design the inputs and outputs for a model that detects potential bombs at a border crossing?

Additional questions. How would you test the model and measure its accuracy? Remember the equation for precision:

Because we can not have high TrueNegatives, recall should be high when assessing the model.

14. Which model would you choose to predict Airbnb booking prices: Linear regression or random forest regression?

Start by answering this question: What are the main differences between linear regression and random forest?

Random forest regression is based on the ensemble machine learning technique of bagging . The two key concepts of random forests are:

• Random sampling of training observations when building trees.
• Random subsets of features for splitting nodes.

Random forest regressions also discretize continuous variables, since they are based on decision trees and can split categorical and continuous variables.

Linear regression, on the other hand, is the standard regression technique in which relationships are modeled using a linear predictor function, the most common example represented as y = Ax + B.

Let’s see how each model is applicable to Airbnb’s bookings. One thing we need to do in the interview is to understand more context around the problem of predicting bookings. To do so, we need to understand which features are present in our dataset.

We can assume the dataset will have features like:

• Location features.
• Seasonality.
• Number of bedrooms and bathrooms.
• Private room, shared, entire home, etc.
• External demand (conferences, festivals, sporting events).

Which model would be the best fit for this feature set?

15. Using a binary classification model that pre-approves candidates for a loan, how would you give each rejected application a rejection reason?

More context: You do not have access to the feature weights. Start by thinking about the problem like this: How would the problem change if we had ten, one thousand, or ten thousand applicants that had gone through the loan qualification program?

Pretend that we have three people: Alice, Bob, and Candace that have all applied for a loan. Simplifying the financial lending loan model, let us assume the only features are the total number of credit cards , the dollar amount of current debt , and credit age . Here is a scenario:

Alice: 10 credit cards, 5 years of credit age, $\$20K$ in debt

Bob: 10 credit cards, 5 years of credit age, $\$15K$ in debt

Candace: 10 credit cards, 5 years of credit age, $\$10K$ in debt

If Candace is approved, we can logically point to the fact that Candace’s $\$10K$ in debt swung the model to approve her for a loan. How did we reason this out?

If the sample size analyzed was instead thousands of people who had the same number of credit cards and credit age with varying levels of debt, we could figure out the model’s average loan acceptance rate for each numerical amount of current debt. Then we could plot these on a graph to model the y-value (average loan acceptance) versus the x-value (dollar amount of current debt). These graphs are called partial dependence plots.

Business Case Questions

In data science interviews, business case study questions task you with addressing problems as they relate to the business. You might be asked about topics like estimation and calculation, as well as applying problem-solving to a larger case. One tip: Be sure to read up on the company’s products and ventures before your interview to expose yourself to possible topics.

16. How would you estimate the average lifetime value of customers at a business that has existed for just over one year?

More context: You know that the product costs $\$100$ per month, averages 10% in monthly churn, and the average customer stays for 3.5 months.

Remember that lifetime value is defined by the prediction of the net revenue attributed to the entire future relationship with all customers averaged. Therefore, $\$100$ * 3.5 = $\$350$… But is it that simple?

Because this company is so new, our average customer length (3.5 months) is biased from the short possible length of time that anyone could have been a customer (one year maximum). How would you then model out LTV knowing the churn rate and product cost?

17. How would you go about removing duplicate product names (e.g. iPhone X vs. Apple iPhone 10) in a massive database?

See the full solution for this Amazon business case question on YouTube:

18. What metrics would you monitor to know if a 50% discount promotion is a good idea for a ride-sharing company?

This question has no correct answer and is rather designed to test your reasoning and communication skills related to product/business cases. First, start by stating your assumptions. What are the goals of this promotion? It is likely that the goal of the discount is to grow revenue and increase retention. A few other assumptions you might make include:

• The promotion will be applied uniformly across all users.
• The 50% discount can only be used for a single ride.

How would we be able to evaluate this pricing strategy? An A/B test between the control group (no discount) and test group (discount) would allow us to evaluate Long-term revenue vs average cost of the promotion. Using these two metrics how could we measure if the promotion is a good idea?

19. A bank wants to create a new partner card, e.g. Whole Foods Chase credit card). How would you determine what the next partner card should be?

More context: Say you have access to all customer spending data. With this question, there are several approaches you can take. As your first step, think about the business reason for credit card partnerships: they help increase acquisition and customer retention.

One of the simplest solutions would be to sum all transactions grouped by merchants. This would identify the merchants who see the highest spending amounts. However, the one issue might be that some merchants have a high-spend value but low volume. How could we counteract this potential pitfall? Is the volume of transactions even an important factor in our credit card business? The more questions you ask, the more may spring to mind.

20. How would you assess the value of keeping a TV show on a streaming platform like Netflix?

Say that Netflix is working on a deal to renew the streaming rights for a show like The Office , which has been on Netflix for one year. Your job is to value the benefit of keeping the show on Netflix.

Start by trying to understand the reasons why Netflix would want to renew the show. Netflix mainly has three goals for what their content should help achieve:

• Acquisition: To increase the number of subscribers.
• Retention: To increase the retention of active subscribers and keep them on as paying members.
• Revenue: To increase overall revenue.

One solution to value the benefit would be to estimate a lower and upper bound to understand the percentage of users that would be affected by The Office being removed. You could then run these percentages against your known acquisition and retention rates.

21. How would you determine which products are to be put on sale?

Let’s say you work at Amazon. It’s nearing Black Friday, and you are tasked with determining which products should be put on sale. You have access to historical pricing and purchasing data from items that have been on sale before. How would you determine what products should go on sale to best maximize profit during Black Friday?

To start with this question, aggregate data from previous years for products that have been on sale during Black Friday or similar events. You can then compare elements such as historical sales volume, inventory levels, and profit margins.

1. Tell Me About Yourself

While this may sound like an open-ended question that you can answer however you like, don't let its simplicity fool you into disclosures that are too casual and personal. The interviewer is trying to get a sense of what kind of person you are and what you value to determine your level of professionalism and how well you would fit on the team.

How to Answer "Tell Me About Yourself"

You might start by focusing on who you are as a professional, since this is a job interview, after all. Tell a bit about your educational and career background and some key facts about your job history. While it's OK (and perhaps expected) to share something that's a little bit personal and unique to you, be careful about what exactly you reveal here. Think in terms of sharing one of your key hobbies or interests outside of work – for example, playing volleyball, cooking or volunteering . Be cautious about revealing details about your age or family status that some employers may be unintentionally biased against.

2. How Did You Find Out About the Position?

The employer is trying to see if one of their marketing methods reached you, or if you found out about the job through some other way.

How to Answer "How Did You Find Out About the Position?"

Whether you learned of the opening from a colleague, online or through a job ad, share the method with the interviewer. You may get brownie points if you happened to have learned about the job from the company's website. If you took extra time to learn about the organization while applying, be sure to mention it.

3. Why Are You Looking for a New Job?

If you already have a job and are conducting a job search, the interviewer might be naturally curious as to what has prompted your desire for change.

How to Answer "Why Are You Looking for a New Job?"

Be careful here, as revealing a dissatisfaction with your current company, boss, or co-workers could serve as a red flag for the hiring team. Instead of complaining about grievances you may have about your current position, focus your answer on your desire for greater opportunities and career growth .

For example, you might say: “While I’ve been excited about the opportunities I’ve had in my current position, I’m looking for a company that I can move to the next level with. I am very invested in this industry and want to be with a key industry player to further my career growth.”

4. Why Do You Want to Work Here?

Hiring managers use this question to try to gauge a candidate's motives for seeking the opportunity. While your primary reason for applying may be financially motivated, this would not be the emphasis to share during the interview.

How to Answer "Why Do You Want to Work Here?"

Think of other reasons you chose to throw your hat in the ring at the specific organization. Maybe you like the company's culture that you read about online, or maybe you've heard from current employees that they love their jobs. If so, spend some time figuring out the best words to use to explain that.

Another good answer could tie back to your career interests. For example, if you're a marketer applying for an entry-level marketing position, you might focus on sharing what it is about the company that makes you feel this would be the right place to develop your career skills in your field.

5. What Interests You About This Job?

This question may seem tricky, since you may feel you don't know enough yet about the job as simply a candidate and not a hired hand. But you can prepare for this query in advance by doing some due diligence before your interview.

How to Answer "What Interests You About This Job?"

Spend at least an hour reviewing the details of the company's job description and determining how to draw links between what the manager wants and the talents you bring to the table. You might even bring a printout of the job description to the interview to refer to specific language as you answer this question. Point out to your interviewer that you have been thinking a lot about the specific needs of the position and how your background and experiences make you the right fit for it.

6. What Motivated You to Apply for This Role?

Early in the interview, you may be asked about why you felt drawn to the position. If the question is phrased to determine your motivation for applying to the role, the interviewer may be trying to determine whether your interest in the role is more self-serving or if it stems from a desire to tackle tough industry challenges that can help the company.

How to Answer "What Motivated You To Apply for This Role?"

A smart way to answer this question is to focus on the latter. Sure, you likely have multiple reasons for wanting the job, but highlight the ones that the company cares about, such as making an impact and helping the team reach their goals, emphasizing that your interest in the company itself was a motivating factor.

You might say something like: “At this point in my career, I have a ton of energy to solve complex problems, and our industry is at an exciting time for this. I chose to apply to your company specifically because of your industry-leading role, plus I love what I’ve heard about your culture.”

7. What Kind of Impact Do You Hope to Have in Your Next Role?

Hiring teams want to know what candidates can do for them, and this impact question gives you the perfect opportunity to impress them with your drive.

How to Answer "What Kind of Impact Do You Hope to Have in Your Next Role?"

The specific type of impact you emphasize will depend on the specific industry or job you’re applying to. But in general, you can stress that you want to build on the skills you bring to the table and that you hope to leverage your experience from your last position to help the company achieve its goals.

For example: “One of my biggest goals that I plan to achieve with my next employer is to take all of my learnings from my career to date to create something big. The first part of my career has been about understanding as much as I can about the industry, and now I finally feel like I’m in the perfect place to have a significant impact in whatever key projects I’m working on.”

8. What Do You Find the Most Stressful About This Type of Role?

This is another potential minefield that you should answer with care, rather than off the cuff. Interviewers are looking for examples that suggest you handle stress well. Your goal is to show that you do know how to manage stressful situations with grace.

How to Answer "What Do You Find the Most Stressful About This Type of Role?"

A winning response might be: “It’s true that this role can be stressful, and I’ve certainly dealt with my share of it in previous positions. If I had to say what the biggest stressor is, I’d pinpoint timing issues. I’m a stickler for meeting deadlines and delivering to my team what I say I will – so when it comes to crunch time, I feel the pressure until I’ve crossed the finish line.”

9. Have You Used Our Product/Service?

You don't want to be caught off guard by this question having not tried out the product or service that you would be working with.

How to Answer "Have You Used Our Product/Service?"

Knowing that this is a common interview question, you would be wise to give the company's tools a test drive prior to your interview, if at all possible. When trying it out, take notes about your experience and share specifics during your interview.

10. How Would You Improve Our Product/Service?

The employer wants to know specifics on the previous question and likely wants to gauge how you give constructive feedback.

How to Answer "How Would You Improve Our Product/Service?"

It takes a bit of diplomacy to navigate your response here, since you don't want to imply with your answer that the product or service is substandard. By coming up with a good idea here – for example, for an additional feature or other bells and whistles that customers might enjoy – you could earn points with the interviewers for your creativity.

11. What's Your Greatest Strength?

The challenge of answering the standard "greatest strength" question is that you want to strike the right balance between sounding confident but not arrogant.

How to Answer "What Your Greatest Strength?"

The strength that you share need not be related directly to the position that you're applying for, but should be clearly tied to an attribute that the specific employer would value.

For example, highlighting your effectiveness working with teams and groups is something that would come in handy in most jobs, so this would be a good choice to share if it's true for you.

12. What's Your Greatest Weakness?

The best answer to this has changed over time. While the go-to response used to be to choose an area that shows your tendency to "care too much" about your job, this response has been overused. If you try it, you may receive pushback from a savvy interviewer who wants you to share a true weakness.

How to Answer "What's Your Greatest Weakness?"

An effective approach is to share something legitimate that isn't your top strength – but also share some concrete ways that you are working on improving in that area.

13. What Do You Hope to Learn and Contribute in Your Next Role?

This question is a variation of the “impact” question, but it’s more targeted at whether you value learning and development, and the contribution you see yourself making in the role, as opposed to what you hope to personally accomplish. Employers are looking for new hires who are eager to learn and be of service to the company.

How to Answer "What Do You Hope to Learn and Contribute in Your Next Role?"

You could say: “I’m always interested in learning new things about our industry, particularly in relation to my own role and self-improvement to help my team. I’m hoping to learn and ultimately master the job, and beyond that, to stay current and keep learning so I can continue to bring value. That way, I can maximize my contribution in my department and eventually, across the company.”

14. What Would You Do in the First 30, 60 and 90 Days on the Job?

Active listening will come in handy here. This common interview question may be hard to prepare for in advance, since details that you learn during the interview itself about the employer's priorities may help you formulate a better, more specific answer.

How to Answer "What Would You Do in the First 30, 60 and 90 Days on the Job?"

If you need a refresher about any points that your interviewers have raised in terms of their priorities, or if they haven't shared them yet, it's fair to ask for clarification before you begin answering. Knowing what the hiring manager cares most about is key to how you should frame your plan for what you would do during your initial months in the position.

15. What Professional Achievement Are You Most Proud Of?

While you may actually consider saving someone's life as a lifeguard in high school to be your proudest moment on the job, don't take this question literally unless you are actually interviewing to be a lifeguard.

How to Answer "What Professional Achievement Are You Most Proud Of?"

The correct approach to describing your greatest professional achievement is to hone in on the position that you're applying for and find a relevant experience in your past career arsenal to showcase something that the hiring manager would hope to find in an employee. An equally smart strategy is to focus on a general accomplishment that would impress any employer, such as creating a tactic to increase your department's productivity.

16. Do You Consider Yourself to Be a Team Player? Why or Why Not?

Be careful here, as interpreting this question too literally can backfire on you. Companies are asking this question because teamwork is essential, on some level, in most roles – even those where you’re primarily an individual contributor. If you don’t consider yourself a team player and prefer to work on your own, it’s best to be diplomatic in how you explain this. Stating your preference is one thing, but flat out saying that you aren’t a team player will backfire and give you a red flag from most interviewers.

How to Answer "Do You Consider Yourself to Be a Team Player?"

If you truly hate teamwork and want to be upfront about it, try stating something along these lines: “I’m honestly an amazing individual contributor since in this role, focus is so important – but I also understand and very much value partnership and collaboration. I’m a team player when it helps everyone achieve our goals, and I’m also very self-motivated to work individually as needed.”

17. What Would Former Co-Workers Say About You?

When asking this question, the hiring committee is trying to gain a sense of your personality, work style and how well you work with others.

How to Answer "What Would Former Co-Workers Say About You?"

While not every past colleague may have reacted to you in the same way, focus on finding commonalities in how people have perceived your best assets. If it is in fact true, then you can't go wrong with indicating that past co-workers and bosses have found you to be a dependable, trustworthy, conscientious and deadline-driven team player.

18. What Annoys You Most About Working With Others?

A variation of the “teamwork” question, this tricky question requires finesse. The employer may be hoping to hear about your pet peeves, or what triggers you the most about your past colleagues – but resist the urge to dish on this. As tempting as it may be to replay your worst work relationship ever, pointing out how annoying this collaboration was, this approach would be a big mistake.

How to Answer "What Annoys You Most About Working With Others?"

Instead, take the high road and keep your answer more general. You might say: “There are always personalities to deal with at work – nobody’s perfect and everyone has their own way of doing things. Sure, co-workers can be annoying sometimes, but I try to notice if I feel annoyed and think about where the other person is coming from. For example, the thing that used to annoy me the most was the way some colleagues didn’t use punctuation in their written communications, like emails, which made the message sound unfriendly. I later realized, though, that this is just a style preference of mine, and it didn’t necessarily reflect any negative intentions from the person who wrote the message."

19. How Would You Describe Your Work Style?

Anyone considering hiring you may want to gain a basic understanding of what your work style is, so that they can determine whether that style will be a fit for the position. Work styles that many employers value are collaborative, team-oriented, detail-oriented, conscientious and supportive

How to Answer "How Would You Describe Your Work Style?"

There are no right or wrong answers here, though if you know something in advance about the types of qualities that this particular employer or company values, then that can help inform your response. For example, if you’re applying for a sales position, it’s more important to emphasize that you’re an energetic go-getter with people skills than if you have a work-from-home job as a graphic designer that you can do independently on your own schedule, where the work style of detail-oriented conscientiousness may be more valued by the hiring team.

20. What Type of Manager Do You Work Best With?

This is a very difficult question to answer when it’s being asked by a potential new boss whose working style you don’t yet know. The best approach here is to keep your comments general, so that you don’t end up describing the opposite of who the interviewer is. Another smart strategy is to express your flexibility in working with a wide range of personalities and management styles.

How to Answer "What Type of Manager Do You Work Best With?"

You might say: “I’ve been fortunate to work with a many different types of managers, and knock on wood, but I’ve gotten along with all of them so far! I value managers who communicate about their needs and the needs of their department, so that I can do my best to help them reach their goals. Beyond that, I think it takes time to adjust to a manager’s style, and I’m happy to work with my manager to create a productive partnership.”

21. What Type of Work Environment Do You Thrive In?

Much like the “type of manager” question, candidates need to step carefully when answering this one in an interview. If you end up describing the opposite work environment than the company offers, then you’ve just talked yourself out of the job. To avoid this, it’s best to frame your answer around flexibility. If you’re offered the job, then you can always explore specific setups and preferences then.

How to Answer "What Type of Work Environment Do You Thrive In?"

If it’s early in your interview process, an open-ended response is a safe bet: “I’ve worked in many different settings, and lots of different company cultures. I’ve found that as long as I have a supportive team and manager, and work that I love, the setting isn’t a deal breaker. I do love what I’ve learned about your company’s culture and work environment, though, and I think I would be a great fit.”

22. Where Do You See Your Career in 3-5 Years?

This question requires some diplomacy, since indicating that you see yourself in the hiring manager's position might not be well-taken. It would also, in most cases, be a faux pas to share your dream of launching a startup, particularly if it's in a different field altogether from the job for which you are currently interviewing.

How to Answer "Where Do You See Your Career in a Few Years?"

A more prudent answer would be to emphasize a vision of yourself making an impact in your industry and mentoring more junior members of your team as you move up the ladder.

23. Tell Me About a Major Challenge You’ve Faced at Work and How You Overcame It

Like with most interview questions, it’s important to tread carefully and phrase your answers in a positive way. This is particularly true with a question like this one that requires addressing difficulties. Your goal should be to share an experience that showcases your ability to persevere and move beyond obstacles without revealing details that could paint you or your colleagues in a negative light.

How to Answer "Tell Me About a Major Challenge You've Faced at Work and How You Overcame It"

While your answer will be unique to your experience, here’s a sample of how to strike this balance: “I once was faced with the challenging situation of needing to generate a key deliverable to the company’s top client in a tight timeframe that made it impossible for me to do everything I wanted. I solved this by recruiting some co-workers from a different department to lend a hand so that we could create the best product possible under the circumstances, and we ended up impressing both my boss and the client.”

24. Tell Me About a Failure You Experienced at Work and How You Handled It

Like the challenge question above, it can be tricky to talk about professional failures and career disappointments. But many employers will understandably want to know how you react in less than optimum circumstances, so you should be prepared to address the question of failure during your interview.

How to Answer "Tell Me About a Failure and How You Handled It"

When discussing missteps, always plan to end on a positive note. And avoid oversharing personal details to make your point; keep it professional and top-level rather than going into the nitty-gritty about the failure.

Here’s a possible response, which you can tailor to your own circumstances: “At my last job, my teammate’s department had been relying on my department to collaborate on a goal they had developed independently of me. I had initially agreed to help out, but quickly realized that doing so would jeopardize my own department’s deliverables to the CEO that week, so I had to pull out of the collaboration before we’d really gotten started. This felt like a failure on my part since I wished I had pushed back initially about my limited bandwidth rather than agreeing on working together. I apologized to my colleague and she understood when I explained about my own deadlines."

25. Is There Anything We Should Know About You That’s Not on Your Resume?

Again, speak carefully here … This question represents an opportunity to share something personal about yourself and make a connection with the hiring team, but avoid letting it all hang out. Managers use this question as a “get to know you,” and it’s a bit of a wild card since it’s very open ended. Your best approach is to stick with fairly neutral topics rather than go out on a limb.

How to Answer "Is There Anything We Should Know About You That's Not on Your Resume?"

While your answer will be very individual based on your own interests, you might share something about either a work achievement that you haven’t had a chance to share yet, and/or a hobby or interest that helps the hiring team see you as a well-rounded person.

Try something like this: “One thing I wanted to be sure to share is that I just joined the Marketer’s Alliance and volunteered for a committee – that just happened so it’s not on my resume yet. Also, I’m a huge gardener. I love to spend time on the weekends rebooting in the garden so that I come back fresh and ready to go, and I find it gives me great balance.”

26. There’s a Gap in Your Employment History – Why?

Astute managers will scrutinize your resume to see if you have a consecutive employment history, and will quickly pinpoint any gaps. If you have a gap in your resume, you need to prepare in advance to explain why you weren’t working for that period of time.

How to Explain Gaps in Employment:

Honesty is the best policy here, and many employers will understand that in times when the job market is tight, some candidates may have gaps in their work history. It helps if you can add some things that you did during your break from employment that facilitated your career goals, such as any volunteer work, education or training that you may have done.

A sample answer: During that period, my entire company faced layoffs, and we had short notice about the fact. I quickly set to work on my job search and landed a position pretty quickly, but it’s true there’s a small gap in my employment history because of that. During the time that I was job hunting, I also took an online course on [add industry topic] to learn a new skill that would help in my next position.

27. Why Should We Hire You?

You should be prepared to respond to this classic interview query no matter what type of position you're applying for, so it's a good idea to prepare and practice your response to it.

How to Answer "Why Should We Hire You?"

If this question comes early in the meeting, use it as a chance to hit on the most relevant points of your experience and skill set, pointing out how well your background fits with the job requirements. If it arrives toward the end of the interview, then take the opportunity to recap the highlights of what you would bring to the company, as well as how you would leverage your abilities to solve the employer's biggest problems.

28. What Are Your Salary Expectations?

If this is your initial interview, err on the side of caution with this question by avoiding specifics. A smart tactic is to switch the question around and ask if a salary band has been identified for the job based on your experience level and location.

Some hiring teams save the most anxiety-producing topic for last: money. Some managers may be hoping that you’ll share numbers based on your prior salary, even though you aren’t obligated to do this – and it’s best to avoid doing so too early in the interview process. You’ll have more leverage as a candidate if you can get the employer to share the job’s salary band first. Otherwise, any number you put out there might end up either too low, pigeonholing you at a lower range than might have been offered, or too high, which might convince the hiring team that they can’t afford you.

How to Answer "What Are Your Salary Expectations?"

An answer like this can help you keep your options open, and hopefully lead to the manager being the first one to share a salary number: “That’s a great question, and I’m hoping you can help guide me on this one. Is it possible to share the range for this position?”

If they won’t share, stay guarded and try to wrap up the discussion by saying something like, “I understand. I’d like to keep this question open to learn more about the job and your needs, and revisit it later in the process.”

29. Do You Have Any Questions for Us?

While you may feel like wrapping up the interview experience as soon as possible, answering with, "No, I think you've covered everything!" won't impress most hiring managers. Instead, you should come prepared to ask some standard questions of the interviewers, which shows that you're interested in learning as much as you can about the position and company.

Some strong questions to ask include:

• What is your favorite thing about working here?
• What are the three biggest challenges that I would face in the position if I'm hired?
• Would I be working directly with you, and what are the other key departments that I'd be working with?
• What is the company culture like, and what do employees like most about it?

15 offbeat interview questions candidates should prepare to answer.

• Share to Facebook
• Share to Twitter
• Share to Linkedin

For job applicants, the interview process offers a vital opportunity to showcase their professional skills and suitability for a company. As such, candidates should put their best foot forward by preparing for potential interview questions.

While most job seekers have a prepared answer for standard or commonly asked questions, they may need clarification when presented with more offbeat lines of questioning. To help, the members of Forbes Human Resources Council share some unique interview questions that could come up and why it's important to have a solid response ready.

1. 'How do you de-stress?'

“What do you do to manage stress or de-stress?” There's no wrong or right answer, but it allows an opportunity for candidates to share what activities they enjoy, and also to incorporate the importance of well-being. This has been a top priority for organizations these past four years and will continue to be included as a benefit in future-forward organizations. - Teedra Bernard , TransUnion

2. 'What gives you energy?'

I ask candidates, "What gives you energy and what drains you in your current role?" The answer gives me insight into the tasks or goals of their current job they enjoy, or have an affinity for, as well as reveals their least favorite tasks or job responsibilities. If their "drainers" make up more than 25% of the job I am considering them for, they probably are not a good fit for the role. - Anne McCafferty , Hale Trailer, Brake & Wheel

3. 'When did you last acquire a new skill?'

"Tell me about the last time you acquired a new skill and how you applied it." With nearly 25% of jobs being set to be disrupted in the next five years, according to the World Economic Forum's latest "Future of Jobs" report , learning agility, the motivation and method to acquire new skills at pace is critical to maintaining relevance and increasing employability. - Catalina Schveninger , Matara Consulting

Best 5% interest savings accounts of 2024, 4. 'how has a setback shaped your growth'.

"Can you share an example of a challenging experience or setback you've faced and how it shaped your professional growth?" It seems like a standard interview question, but it's important because it focuses on assessing qualities like resilience, grit and a growth mindset over technical skills, and allows employers to gauge how candidates handle adversity and learn from it. - Tia Smith , Cognizant

5. 'What did you learn from failure?'

"Talk to me about a time you have failed. What did you learn from it?" With the rise of AI and technology across all fields, organizations are looking for individuals willing to innovate and learn. With trying new things, ideas and technologies, the chance of failure also exists. Companies are looking for individuals willing to learn, fail, innovate and succeed. - Amee Parekh , Stello Technologies

6. 'How do you learn new systems?'

"What systems and/or technology have you used, and what's one thing you do to hold yourself accountable to learning a new system? Please provide an example." As technology evolves and alternative technologies emerge, it's important that candidates not only have experience using multiple systems but that they've had to learn and adapt to new systems within an existing organization. - Jenna Hinrichsen , Advanced RPO

7. 'Are you willing to work in person?'

One question every candidate should be ready to answer, especially for a remote job, is, "Would you be willing to shift to an on-site or hybrid role if your employer required you to do so?” This question establishes expectations upfront for possible location-related situations and is a timely topic being addressed in the hiring and recruitment industries right now, with varying opinions. - Laura Spawn , Virtual Vocations, Inc.

8. 'What don't you want here?'

Candidates are also screening us, so a good question is, "What is something that you wouldn't like to find here?" Not only will you know if they heard what you were saying or if they researched about your company, but you also could understand what the person values the most (leadership, communication, benefits, training, development and so on). You can know if it's a proper fit. - Marcela Pizzi , Atlas Renewable Energy

9. 'How are you using AI currently?'

"How are you using AI?" Being ready to discuss your experience and views on AI signals that you're knowledgeable about this emerging field and its impacts on the future of work. It also shows your technology fluency and that you can apply AI to solve problems and increase productivity. This "AI readiness" question cuts to the chase in assessing a candidate's technology IQ and literacy. - Nicole Smartt Serres , Smartt Enterprises

10. 'How would you use AI in this role?'

"How would you use AI to bring more efficiency to this job?" This question would get both at how deeply the candidate understands the role and responsibilities and also how familiar they are with the uses of AI to be able to think about some practical ways they could apply it for their job. - Sanja Licina , QuestionPro

11. 'How do you handle ambiguity?'

“How do you handle ambiguity?” Change is a cornerstone of the 2024 job market, so find out how candidates will complete tasks, even with limited information or experience. Do they struggle to deal with change or can they pivot as new challenges arise? Adaptability is an essential soft skill. - Ursula Mead , InHerSight

12. 'What concerns did you have about the job?'

"What specific concern (from research) gave you pause about our company, and how did you overcome it?" The benefits: 1. It's engaging and introspective, and prompts reflection and honest dialogue, 2. It uncovers potential concerns and shows the candidate's ability to research and address them, 3. It gauges resilience and problem-solving and demonstrates the ability to overcome doubts. - Michael D. Brown , Global Recruiters of Buckhead

13. 'How do you fit into our culture?'

“How do you see yourself fitting into our organizational culture?” Recruiters are increasingly recognizing the importance of hiring candidates who align with their employer’s mission, values and culture. Any job candidate should be prepared to talk about how they would fit into the organization’s culture and how they would contribute. - Niki Jorgensen , Insperity

14. 'How do you start your day?'

One question that I've heard hiring managers use is "Tell me about how you start your day." It can catch candidates off guard. What they are looking for is whether you are intentional and structured about your time. Talking about spending time planning your day, listening to educational podcasts, reading, meditating, exercising and so on are all great responses and tell a lot about a person. - Hazel Kassu , Sudduth Search

15. 'How did you adapt to tech evolution?'

"How did you adapt to a rapidly evolving technology environment?" The question probes the candidate's adaptability, learning agility and innovation skills. - Britton Bloch , Navy Federal

Title: do llms find human answers to fact-driven questions perplexing a case study on reddit.

Abstract: Large language models (LLMs) have been shown to be proficient in correctly answering questions in the context of online discourse. However, the study of using LLMs to model human-like answers to fact-driven social media questions is still under-explored. In this work, we investigate how LLMs model the wide variety of human answers to fact-driven questions posed on several topic-specific Reddit communities, or subreddits. We collect and release a dataset of 409 fact-driven questions and 7,534 diverse, human-rated answers from 15 r/Ask{Topic} communities across 3 categories: profession, social identity, and geographic location. We find that LLMs are considerably better at modeling highly-rated human answers to such questions, as opposed to poorly-rated human answers. We present several directions for future research based on our initial findings.
