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 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.

  • Were there any "dealbreakers" involved in your decision to become a customer?

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-questions_2

Before you can start putting together your case study, you need to ask your customer's permission.

If you have a customer who's seen success with your product, reach out to them. Use this template to get started:

Thank you & quick request

Hi [customer name],

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]

case studies questions and answers

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.

My team is actually in the process of building out our library of case studies, and I'd love to include your story. Happy to provide more details if you're potentially interested.

Either way, thank you again, and I look forward to getting more updates on your progress.

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.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

What is a Case Study?

A case study is a research method used to study a particular individual, group, or situation in depth. It involves analyzing and interpreting data from a variety of sources to gain insight into the subject being studied. 

Case studies are commonly used in fields such as psychology, business, and education to understand complex issues and develop solutions. They typically include detailed descriptions of the subject, background information, and an analysis of the key issues involved. 

The goal of a case study is to provide a comprehensive understanding of the subject, as well as to identify potential solutions or recommendations.

How Long Should a Case Study Be?

What you need to include in your story will depend on the type of discipline. For example, a kitchen remodeling company could tell its entire story with pictures. Whereas this approach may not be suitable for a software invoicing solution.

Consider this pro advice while crafting your case study:

  • Most sources indicate that it should consist of 500-1500 words.
  • To ensure that your message is concise and crystal clear, add a brief snapshot section of 100 words or less.

What Is a Marketing Case Study?

This type of case study focuses on a particular marketing challenge or problem. It analyzes the strategies used to overcome the challenge and achieve a successful outcome. 

Marketing case studies can be used to showcase effective marketing tactics, as well as to learn from failures and avoid common pitfalls. They often include details about the target audience, marketing channels used, and metrics to measure success. 

Marketing case studies are commonly used in business courses to help students understand marketing challenges and develop strategies.

Marketing Case Study Examples

Marketing case studies are real-life stories that showcase how a business solved a problem. They often discuss how a business achieved a goal using a specific marketing strategy or tactic.

They typically describe a challenge faced by a business, the solution implemented, and the results achieved.

The purpose of a marketing case study is to demonstrate a business's expertise and ability to solve problems. This is done to show their potential to customers.

Here are some examples that show how companies use case studies as a means of marketing and promotion:

1- "Chevrolet Discover the Unexpected" by Carol H. Williams 

This case study explores Chevrolet's DTU Journalism Fellows program. The case study uses the initials "DTU" to generate interest and encourage readers to learn more. There are multiple types of media such as images and videos used to explain the challenges faced. The case study concludes with an overview of the achievements that were met:

Key points from the case study include:

  • Using a well-known brand name in the title can create interest.
  • Combining different media types, such as headings, images, and videos, can help engage readers and make the content more memorable.
  • Providing a summary of the key achievements at the end of the case study can help readers better understand the project's impact.

2- “The Met” by Fantasy

Fantasy's case study for the Metropolitan Museum of Art, titled "The Met," provides a clear and simple showcase of the museum's website redesign. The case study emphasizes the features and interface of the website by showcasing each section of the interface individually, allowing the readers to concentrate on the significant elements.

For those who prefer text, each feature includes an objective description. The case study also includes a "Contact Us" call-to-action at the bottom of the page, inviting visitors to get in touch with the company.

Key points from this case study include:

  • Keeping the case study simple and clean can help readers focus on the most important aspects.
  • Presenting the features and solutions with a visual showcase can be more effective than writing a lot of text.
  • Including a clear call-to-action at the end of the case study can encourage visitors to contact the company for more information.

3- "In-Depth Performance Marketing Case Study," by Switch

This impressive case study presented by an international marketing agency, Switch, effectively communicates its client's success without revealing their name. To keep non-marketers in the loop, Switch includes a glossary of terms. The case study is presented in a fourteen-page PDF that's easy to skim, featuring big fonts and white space. Each page covers a different strategy, making it easy to navigate.

To provide readers with an overview of the client's requirements and reasons for approaching Switch, the Switch case study employs titles such as "Scenario," "Approach," and "In-Depth Performance Marketing Case Study" at a higher level. The PDF also features a CTA page and contact information for prospective clients.

Key points from the Switch case study:

  • Include a glossary of terms to make specialized information accessible to non-specialists.
  • Make your case study easy to navigate by using titles and separating sections.
  • Close with a CTA page and include contact information for prospective clients.

4- “Better Experiences for All” by Herman Miller

Herman Miller's minimalist approach to furniture design translates to their case study page for a Dubai hospital. The page features a captivating video with closed-captioning and expandable text for accessibility.

The case study presents a wealth of information in a concise format, enabling users to comprehend the intricacies of the strategy with ease. It concludes with a client testimonial and a list of furniture items purchased from the brand.

Key points from the case study:

  • Make sure your case study is user-friendly by including accessibility features like closed captioning and expandable text.
  • Include a list of products that were used in the project to guide potential customers.

5- “NetApp” by Evisort

The NetApp case study by Evisort is an excellent example of an informative, thorough, and compelling case study. Evisort starts off the case study with an at-a-glance overview of the client, NetApp. This approach helps to focus the attention on the client rather than the company or team.

The case study features client quotes and delves into the obstacles that NetApp encountered during the COVID pandemic. By highlighting how its services helped NetApp during tough times, Evisort demonstrates its value as a partner to their clients.

To make the case study accessible in a wider variety of formats, Evisort provides access to download their study in PDF format. This is an important consideration for making the case study easy to share and reference.

Key points from the Evisort example:

  • Provide an overview of the company in the client’s words and put focus on the customer. 
  • Highlight how your services can help clients during challenging times.
  • Make your case study accessible by providing it in various formats.

6- "Red Sox Season Campaign," by CTP Boston

The case study for the Red Sox Season Campaign by CTP Boston showcases a perfect blend of different media, such as video, text, and images. Upon visiting the page, the video plays automatically, and as you scroll, you'll find more videos featuring Red Sox players, social media images, and print ads that can be enlarged with a click.

The page features a clean and cohesive design that is visually appealing and invites viewers to appreciate CTP's well-rounded campaign for Boston's beloved baseball team. At the bottom, the page includes a call-to-action that encourages viewers to learn how CTP can create a similar campaign for their own brand.

Key points to take away:

  • Including a variety of media such as video, images, and text can make your case study more engaging and compelling.
  • Include a call-to-action at the end of your study that encourages viewers to take the next step towards becoming a customer or prospect.

7- “Zapier Case Study” by Ryan Berg

Ryan Berg's SEO case study on Zapier is an excellent example of an explanatory case study that can be used for marketing purposes. The study provides a comprehensive breakdown of Zapier's SEO strategy and how they created over 25,000 unique landing pages to improve their search rankings for different search terms.

One of Zapier's key strategies involved targeting relevant long-tail keywords such as "app A + app B integration," which helped them generate significant organic traffic over the long term. By analyzing the success of industry leaders and breaking down their strategies, businesses can borrow their brand power and credibility.

Explanatory case studies like this one are particularly useful when clients are not comfortable with sharing detailed information about their growth tactics. Such case studies can demonstrate a company's expertise and credibility to potential clients, proving their ability to help them succeed in their industry.

  • Targeting relevant long-tail keywords is an effective strategy for generating organic traffic.
  • Analyzing the success of industry leaders can provide valuable insights for developing a successful strategy.
  • Explanatory case studies can demonstrate a company's expertise and credibility to potential clients.

8- “Video Marketing Case Study” by L’Oréal and YouTube

The case study on L’Oréal and YouTube showcases the success of their video marketing campaign to launch a new product. The global marketing team members explain how they strategically used YouTube ads to achieve impressive results, including establishing the new product as the second-best in its category and generating 34% of all mass sales among online retailers. 

The case study provides a detailed breakdown of the various stages of the campaign, from awareness to loyalty, highlighting the effective use of YouTube at each step. It serves as a great example of a third-person implementation case study that demonstrates the power of video marketing.

Key points for learning:

  • Use YouTube ads strategically for different stages of a campaign, from awareness to loyalty.
  • Effective use of video marketing can lead to impressive results, such as establishing a new product as a leading player in its category and generating significant sales.
  • Third-person implementation case studies can showcase your expertise and the success of your marketing strategies to potential clients.

9- “Airbnd + Zendesk” by Zendesk

The case study by Zendesk, titled "Airbnb + Zendesk: building a powerful solution together" showcases a true partnership between Airbnb and Zendesk. The article begins with an intriguing opening statement, "Halfway around the globe is a place to stay with your name on it. At least for a weekend," and uses stunning photographs of beautiful Airbnb locations to captivate readers.

Instead of solely highlighting Zendesk's product, the case study is crafted to tell a good story and highlight Airbnb's service in detail. This strategy makes the case study more authentic and relatable.

Key points to take away from this case study:

  • Use client's offerings' images rather than just screenshots of your own product or service.
  • To begin the case study, it is recommended to include a distinct call to action. For instance, Zendesk presents two alternatives, namely to initiate a trial or seek a solution.

10- “Influencer Marketing” by Trend and WarbyParker

The case study from Trend and Warby Parker highlights the potential of influencer marketing, even when working with a limited budget. The "Wearing Warby" campaign involved influencers wearing Warby Parker glasses during their daily activities, providing a glimpse of the brand's products in use. 

This strategy helped to make the brand more relatable to the influencers' followers. Although the case study does not delve deeply into the tactics used, it demonstrates the effectiveness of third-person case studies in showcasing the results of a campaign.

  • Influencer marketing can be effective even with a limited budget.
  • Showcasing products being used in everyday life can make a brand more approachable and relatable.
  • Third-person case studies can be useful in highlighting the success of a campaign.

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!

case studies questions and answers

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?

case studies questions and answers

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?

case studies questions and answers

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)

case studies questions and answers

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.

33 Case Study Questions for Customer and Client Interviews

case studies questions and answers

When selling your product or service to prospective customers, you make a stronger case when you can show concrete results. This is where a case study comes in. A case study strengthens your sales pitch by showing firsthand results. You can boost your case studies by interviewing previous customers and asking them to share how they benefited from your business. Interview your loyal customers using the following questions to build strong case studies you can share with new prospective clients.

What is a Case Study?

A case study is a detailed report that showcases how your product has benefited previous clients. It is a way to show firsthand how your product or service can benefit potential new clients. Case studies help you build trust with new clients — 88% of whom trust online customer reviews and ratings. Conversely, only 14% of customers trust advertisements.

Asking the right types of questions to your previous customers will help you better craft your final case study. Since you will be writing these studies with new clients in mind, drafting your questions beforehand will give you the right information to highlight how you have previously solved similar client issues in the past.

How to Write Case Study Questions

This section offers an outline of sections that should be included in your final case study and sample questions to ask of your clients.

Start With the Backstory

Before writing your case study questions, determine why you are writing it. Outline the major problems you intend to highlight and create questions that will allow you to articulate how you solved them. The following section includes case study question examples you can use to conduct your client interviews, but you can modify them based on your goals.

When interviewing your previous clients, first introduce them to your audience by including some background information on their company. Next, set up the case study by presenting the initial problem.

  • Tell me a little bit about your business and its history.
  • Who are your target customers?
  • Describe your role at the company.
  • What are some common challenges faced by businesses in your industry?
  • What problems or challenges were you facing that led you to seek out our product/service?
  • Why was this specific challenge a priority?
  • How was this problem impacting your business?
  • What other potential solutions had you tried before, and why weren’t they working?

Establish Your Relationship

After setting up the problem and why it was significant to your customers, ask them to define their relationship with your brand. If you are interviewing repeat customers, ask them how they discovered your business, why you were their chosen solution, and what's kept them coming back. If you are interviewing a first-time client, ask what drew them to your business over another.

Some questions can include:

  • How long have you been a customer with us?
  • How did you first hear about our business?
  • What made you choose our company over competitors?
  • How did you envision using our product or service to drive your solution?

Have Them Demonstrate Your Product

Once you have set up the initial problem and delved into how your client chose you to solve it, you can get into the details of the actual case study. Ask specific questions about how your client used your product or service.

Be detailed. These answers will help you draft a case study that resonates with prospective buyers who are facing the same issue.

  • How did you use our product or service to create your solution?
  • Which features of the product did you find most beneficial?
  • Was this product a replacement for a similar tool you had used in the past?
  • How many people at your company use our product?
  • What are the advantages of using our product over another similar one?
  • How was the setup and implementation process?
  • Did you contact the customer service team any time during the process?
  • If so, how was your customer service experience?
  • How was the rollout process?
  • What types of feedback have you received from employees about our product?

Outline the Product’s Benefits

This section of your interview will delve into the actual solution and its results. Use this section to ask about specific outcomes and metrics the company used to track successes.

  • How did our product address your specific challenges?
  • What kinds of measurable results did you see?
  • Which key performance indicators (KPIs) or metrics did you measure to determine whether our product successfully solved your problem?
  • How has your business changed since you deployed our product or service?
  • How is your initial problem currently impacting your business? Is it still an issue, or has it been resolved?
  • How would you recommend other customers use our product to get the best results?

Wrap Up the Interview

At the end of the interview, ask some general business case study questions relating to customer satisfaction and relationship management. You can use these to conclude the case study. This section of the interview is also likely to generate some potential customer quotes you can use in your marketing materials .

  • Have you referred us to your friends or clients?
  • How likely are you to work with us again?
  • How can we improve our product to best meet your future needs?
  • In which other instances can you see our product providing a viable solution?
  • Is there anyone else I can talk to for more information?

How to Ask Your Clients for an Interview

If you have been in business for a while, you probably know your best advocates. Think about your top customers, and start by asking those who are the most likely to promote your business. If you know a client who often refers customers to you, ask them for a specific example of how your company helped them solve a problem.

You might draw a blank when asked to identify your best advocates. In this case, talk to your sales team or your project managers to see if they know of any potential customers who would be happy to share their success stories.

Consider your customers’ time. Don’t approach them for an interview in the middle of a busy season or if they have had a recent issue with your company. Get familiar with your selected clients and how they intended to use your product so you have some background information before starting the interview.

Finally, write a personalized request. Don’t send out a form email requesting case studies. Make your requests relevant to each potential interviewee so they know they are valued customers.

How to Write the Case Study

Instead of taking notes during the interview, take a recording on your phone or a portable recording device and transcribe it when you’re done. You can take minor notes as you go along, to help when you go back to transcribe. This way you can be more engaged in the interview and follow up on interesting information that might pop up. Be sure to check that your recording hardware or software is working ahead of time, to ensure you don't lose valuable information during the interview.

The case study questions listed above are arranged as an outline of a typical case study. Start by introducing the company and the problem they were trying to solve when they sought out your business. Next, explain the process of how they used your product to solve their problem.

End the case study with numbers and statistics demonstrating how you helped the business successfully solve its problem. Make sure you get specific numbers and figures to illustrate your clients’ successes. If you don’t get them during the initial interview, follow up with a phone call or email.

Sample Case Study Questions and Answers

These sample case study questions and answers demonstrate how to extract information from your interview and turn it into an engaging business case study that is interesting and informative.

This case study from Switch, a digital marketing agency, details how the company was able to help a client improve its return on investment (ROI) on search and Facebook ad campaigns by moving them from their in-house marketing team.

The case study starts with an impressive statistic — the company improved its ROI on search ads from 1.2x to 19x in a short time period. The case study breaks this statistic down for potential leads who might not be familiar with marketing terminology, indicating that its client was able to increase sales without spending more on search engine ads.

While the actual case study interview is not published, a sample question and answer that would have generated this data could be:

  • Q: How did shifting the development of search engine ad campaigns to Switch impact ad performance?
  • A: The Switch team was able to change our approach. Before, we used a single strategy on our search and Facebook ads. Their team was able to create split campaigns targeted to different audiences and run A/B tests to refine the messages. In a couple of months, our ROI on search ads went from 1.2x to 19x.”

This case study goes into detail about how Switch worked with its clients to refine the Facebook and search ad strategy, ending with impressive results.

Rogers Communications

Rogers Communications featured this case study detailing how its client Brampton Caledon Community Living (BCCL) used the company’s cloud-based mobile phone system to better service clients. This case study is simple, laid out with headings like “Challenge” and “Solution.”

Rogers Communications pulled relevant quotes from the client and included them in text boxes throughout the study to break up the text. Rogers also included direct quotes from personnel at BCCL, making a strong case for its product. While it doesn’t offer hard numbers like the previous example, it does include a quote detailing how the cloud-based system has improved the work environment.

Again, the interview for this case study is not included in the example, but it does include the answers as client quotes.

  • Q: What led you to switch over to the RogersUnison cloud-based platform?
  • A: “We had been using more laptops and mobile phones for work outside the office and Rogers Unison was essential to this transition.”

Best Practices for Conducting A Business Case Study Interview

When you’ve found client advocates who are willing to talk to you about how your company led them to success, draft your interview questions. Keep these best practices in mind.

Be Prepared

Being well-prepared for your interview is the best way to ensure its success. Before meeting with your client, learn what you can about the client so you can flesh out the case study. Conduct a mock interview to prepare. Talk to your sales team or the client’s specific project manager for details to better understand the client and what they were facing when they hired your company or purchased a product.

Ask Open-Ended Questions

Structure your questions so the interviewee has to give detailed answers. If you limit your interview to "yes" or "no" questions, it can be hard to gather enough information to write your case study. Open-ended questions let your client get into the specifics surrounding the study.

Do a Deep Dive

One reason you should record your interviews and transcribe them later is so you can focus on the client’s answers. Often, information will come up in an answer to one question that will prompt you to ask a follow-up question. Recording your interview lets you deviate from your prepared questions to get a more robust analysis of the case.

Getting Started on Your Case Study

Case studies are a great marketing tool for building credibility. They give prospective clients a better understanding of how you work and how you can provide alternative solutions for key issues. But the key to writing a good case study is to start with a quality interview.

You have the tools needed to draft powerful questions. So start the process by looking through your list of past clients and determining who would be the best to interview. Develop a thorough understanding of their situation and their history with your company, and then conduct your interview.

After your first few case studies, you'll be confident on how to best structure questions and refine your interviews to get the best information. Soon, you will be crafting detailed and engaging case studies to best market your business.

Answering essay questions in exams

Writing an essay in an exam is similar in many ways to writing an essay for an assignment: It needs to be clearly structured, and your ideas need to be linked and supported by evidence.

Essay questions in exams

  • Read the question through carefully to make sure you are answering what has been asked.  Missing one part of a question can cost you a lot of marks.
  • Make a quick plan of the points you want to include in your answer.
  • Use essay structure: introduction, points, conclusion.  But if you run out of time, it can be a good idea to write notes.
  • Get right to the point from the beginning.  Use the words from the question to write your first sentence. For example:

Question: What do you think is the most important intercultural communication issue in New Zealand? First sentence: At present in New Zealand the most important intercultural communication issue is...

  • Remember to include one idea per paragraph, and to begin each paragraph with a clear topic sentence.
  • Make sure your writing is legible.
  • Grammar, punctuation and spelling are not as important as in an assignment but should still be of a good standard.

Answering case study questions

Exam questions that ask you to anlayse case studies (also called scenarios) are usually designed to test your ability to relate theories and concepts to real-world situations.

Preparing for case studies before the exam:

  • Start by identifying the theories and concepts covered in your course.  Organise and review the information you have on these theories/concepts so you understand them.
  • Practice reading case studies and identifying relevant information. It's probably useful to practice doing this with a time limit as you will have one in your exam.
  • Practice relating concepts and theories to real-world situations: ask lecturers and check textbooks for practice examples. It is also worth checking past exams for your course to see if there are examples of case study questions.

During the exam

  • Take time to plan: Have a clear idea of how much time you have to answer the question. Then plan to spend some time reading the exam question, the case study and planning your answer. Take time to make sure you have understood the case study and know what the exam question is asking you to do:
  • Read the exam question(s)
  • Then skim read the case study to get the general idea. Highlight or underline key points
  • Reread the question to make sure you understand it and to focus your attention when you reread the case study.
  • Reread the case study carefully. Make a note of any ideas that you think of.
  • Answer the question linking relevant theories and concepts to specific information from the case study. Usually you will need to write your answers in clearly formed paragraphs which have a clear topic that is well-supported with evidence and examples.
  • Instead of simply describing or restating information from the case itself, use specific details or examples to support the points you are trying to make. This is where you link theory to the facts from the case study.

Cracking the Case Interview: Your Guide to Sample Questions and Answers

Austin Anderson

Reviewed by

Expertise: Consulting | Data Analysis

Consulting is among the most sought profession by business management graduates. The top three consulting firms are abbreviated as MBB ( McKinsey , Boston Consulting Group , and Bain ), also known as the Big Three .

case studies questions and answers

Since most consultancy firms work on various kinds of problems, they look to hire people with the best critical thinking abilities who can tackle challenges faced by their clients by applying well-known frameworks for problem-solving.

Hence, most consulting firms rely on case studies as a crucial part of the interview process. Nailing these case studies can be the difference between landing a role as a consultant or leaving empty-handed from an interview.

However, most case studies can be solved with existing frameworks like Porter’s five forces, SWOT analysis , and the 4 Ps. Learning these frameworks and walking through them during the interview helps differentiate yourself as a star candidate.

We strongly believe it’s a great place to start your preparation before investing in our more comprehensive Consulting Case Interview Course, which features more than 2,000 questions.

Consulting Case Interview Tips

  • Prepare to be assessed on your thinking and problem-solving abilities.
  • Familiarize yourself with frameworks like Porter's five forces and SWOT analysis.
  • Note essential information and critical relationships in the case study.
  • Use proven approaches and frameworks to analyze and answer questions during the interview.
  • Candidates are evaluated on demeanor, structure, communication, math proficiency, and creativity.

Consulting Case Interview Example

Every case study interview starts by providing some background information on the case, which helps you understand the problem you are tasked with finding a solution to. It is essential to separate the necessary information from the useless ones, as this skill is highly sought after. 

case studies questions and answers

Also, make sure to note down all the critical relationships between the date provided. For example, suppose the case first mentions that profits have been declining, and later mentions something about reducing marketing costs.

In that case, it’s a good idea to jot down that it might be a factor in lowering profits (reduction in marketing costs means lower revenue, which in turn means lower yields).

For this sample case, we will use the example of Cali Cable and present it just like how an interviewer would.

Sample Case Prep: Cali Cable

Cali Cable is a small business that operates in northern California. Their core business is installing cable infrastructure in residential neighborhoods so that the homes have access to cable television. Cali Cable has manufactured its own cable since it has been in existence. 

case studies questions and answers

However, the factory is out of date and must be shut down. The CEO does not want to open a new factory because it will be expensive, costing as much as $15 per foot of cable. Therefore, he is considering outsourcing cable manufacturing from either a local supplier, an Asian supplier, or an Eastern European supplier. 

He is experiencing problems with the local supplier, so he asked the COO to find the most cost-effective way to find a reliable cable supplier elsewhere. You are assigned to work with the COO to find the best course of action.

Sample Consulting Interview Questions and Frameworks

Based on the case study above, the interviewer will proceed to ask you questions that test your critical thinking and analysis skills. Hence, it is very important to properly understand the case first, ask the right questions, and follow a proven approach.

case studies questions and answers

1. How should the COO approach outsourcing?

Framework:  A 2x2 for an outsourcing case is a valuable framework.

  • For the x-axis competitiveness, the candidate should consider Cali Cable’s effectiveness in terms of costs. 
  • For strategic importance, the candidate should think about how the cable is important to the company’s overall goals. For example, how is the quality of an outsourced line going to threaten customer satisfaction?

case studies questions and answers

The candidate should also consider the costs and risks of outsourcing. The tree below could be useful.

case studies questions and answers

2. The COO approaches you. She has collected some data and wants you to analyze it and prepare a PowerPoint presentation slide for a meeting with the CEO. The template for the slide is as follows.

case studies questions and answers

The COO has found that the Asian supplier will charge $7 per foot of cable with a fixed payment of $600,000 per year. The Eastern European supplier will charge $6 per foot of cable and $800,000 in fixed costs. Complete the blank slide for the COO plotting the total cost per foot for the two different options for 100K, 200K, 300K, and 400K feet.

Answer:  The candidate is instructed to create her own slide on her scratch paper.

case studies questions and answers

You should immediately recognize the economies of scale resulting from the fixed  cost structure of the two outsourcing options. If not, try to explain the graph. All three plants cost $10 per foot at 200,000 units, but the Asian and Eastern European plants enjoy the benefits of scale beyond this point.

The Eastern European plant becomes the clear cost leader past 200,000 units.

3. The COO thinks she has a good feel for demand based on historical data. She calls you and says, ‘for the past few years, Cali Cable has used about 50 miles of cable per year, so we’ll order 50 miles of cable from our new supplier for next year.’ What should you tell her?

Considering the standard deviation and service level, how much cable should be ordered annually how much will cali cable save compared to the local supplier if it goes with the eastern european option.

Answer:  Because the COO wants to satisfy demand 98% of the time, the 400,000 feet of cable is the relevant footage on the x-axis of the cost graph. With the Eastern European plant costing $8 per foot for 400,000 units, Cali Cable will save $800,000 per year ($2 times 400K feet).

4. What else should the COO consider to reduce costs?

Answer:  Consider at least four different options. We have highlighted the four below:

  • Warehouse: store any excess supply in a warehouse and adjust order levels for the next year. Inventory carrying costs should be compared to the costs of mismatching supply and demand. 
  • Increase the number of orders: annual orders result in costs from stock-outs or excess supply. If Cali Cable can order throughout the year, it can better match supply and demand. 
  • Shorten lead times: this could also fall under increasing the number of orders. Shorter lead times from the supplier to Cali Cable will allow them to postpone ordering and have more information about demand forecasts. 
  • Explore other options and suppliers: for example, when demand exceeds supply, locate excess capacity at other cable operations or use the local supplier at $10 per foot when the cable is needed. This allows Cali Cable to order less.
  • Better forecasting: find a more accurate way to forecast demand or have customers commit to quantities in advance.

5. What are some of the risks to outsourcing to Asia or Eastern Europe?

Answer:  There are many different risks to consider. We have named a few below under the relevant bucket.

  • Product Risks: Will the cable be compatible with American cables and televisions? Are there any risks to the cable becoming obsolete? With the growth in high definition, 3D, and internet television, the supplier needs to be able to stay up to date with technology. 
  • Company Risks: Is the Eastern European or Asia supplier a sustainable company that will be able to deliver into the future? If Cali Cable sources exclusively from a new supplier, their fortunes are tied.
  • Operational Risks: Will the new supplier be successfully integrated with the supply chain logistics at Cali Cable? Are there any risks to shipping cable from Europe or Asia? Will it be shipped via boat or plane? What are the lead times? How reliable is this company in delivering on time? 
  • Customer Service Risks: Will the quality of the cable meet the customer’s expectations? What are the risks to over or under-ordering cable?

6. Using the PowerPoint slide you prepared with the COO, present your recommendation to the CEO.

Recommendation:  The CEO wants the most cost-effective supplier, but the candidate should also mention the reasons behind the decision and the risks involved. A possible recommendation: 

“For our cost structure to remain competitive, it looks like outsourcing is the best option. As long as the outsourced cable meets our quality standards, it appears to align with our corporate strategy . Cali Cable should consider outsourcing its cable from Eastern Europe because it is a low-cost option. 

Show the PowerPoint slide. Due to the fixed cost structure, Cali Cable will enjoy economies of scale with both offshore options, but Eastern Europe appears to be the most attractive. Cali Cable will save $800,000 per year compared to the local supplier and $200,000 per year compared to the Asian supplier. 

Before proceeding, I’d like to find out more about the risks associated with the Eastern European supplier, such as their reliability, quality, ordering processes, and ability to integrate with our supply chain.”

How are management consulting case interviews graded?

Interviewers usually grade the candidates over a variety of qualities using a scale ranging from 1 to 10, with one meaning poor and ten meaning star.

case studies questions and answers

We look into the various qualities that are evaluated, as well as questions used to measure them. These questions should give you a good feel for what you need to focus on to ace these consulting interview cases.

  • Did she use appropriate assumptions or clarify any ambiguity?
  • Did she think out loud so that you could follow the calculations?
  • Did she think outside the box?
  • Did she mention any current events or recent trends affecting the industry?

Recommendation

  • Did she answer the question?
  • Was the conclusion clear, confident, and to the point?
  • Did she justify the conclusion with the key findings?

Let me ask you a question: Have you ever bought something — within the last 10 years or so — without reading its reviews or without a recommendation or prior experience of using it?

If the answer is no — or at least, rarely — you get my point.

For businesses selling consumer goods, having raving reviews is a good way to get more customers. The same thing applies to B2B and/or SaaS businesses — but for this type of business, besides regular, short reviews, having a detailed case study can help tremendously.

Case studies are an incredibly effective form of marketing that you can use to help promote your product and plan your marketing strategy effectively. You can also use it as a form of customer analysis or as a sales tool to inspire potential customers.

So what does a case study look like and how can you create one? In this article, I’m going to list over 15 marketing case study examples, case study tips, and case study templates to help you create a case study that converts.

What is a case study?

A case study is a research method to gain a better understanding of a subject or process. Case studies involve in-depth research into a given subject, in order to understand its functionality and successes.

In the context of a business, however, case studies take customer success stories and explore how they use your product to help them achieve their business goals.

As well as being valuable marketing tools, case studies are a good way to evaluate your product as it allows you to objectively examine how others are using it.

It’s also a good way to interview your customers about why they work with you.

What is a marketing case study?

A marketing case study is a type of marketing where you use your existing customers as an example of what your product or services can achieve. You can also create case studies of internal, successful marketing projects.

Here’s an example of a marketing case study template:

Marketing case studies are incredibly useful for showing your marketing successes. Every successful marketing campaign relies on influencing a consumer’s behavior, and a great case study can be a great way to spotlight your biggest wins.

In the marketing case study examples below, a variety of designs and techniques to create impactful and effective case studies.

Show off impressive results with a bold marketing case study

Case studies are meant to show off your successes, so make sure you feature your positive results prominently. Using bold and bright colors as well as contrasting shapes, large bold fonts, and simple icons is a great way to highlight your wins.

In well-written case study examples like the one below, the big wins are highlighted on the second page with a bright orange color and are highlighted in circles.

Making the important data stand out is especially important when attracting a prospective customer with marketing case studies.

Use a simple but clear layout in your case study

Using a simple layout in your case study can be incredibly effective, like in the example of a case study below.

Keeping a clean white background, and using slim lines to help separate the sections is an easy way to format your case study.

Making the information clear helps draw attention to the important results, and it helps improve the  accessibility of the design .

Business case study examples like this would sit nicely within a larger report, with a consistent layout throughout.

Use visuals and icons to create an engaging and branded business case study

Nobody wants to read pages and pages of text — and that’s why Venngage wants to help you communicate your ideas visually.

Using icons, graphics, photos, or patterns helps create a much more engaging design. 

With this Blue Cap case study icons, colors, and impactful pattern designs have been used to create an engaging design that catches your eye.

Social Media Business Case Study template

Use a monochromatic color palette to create a professional and clean case study

Let your research shine by using a monochromatic and minimalistic color palette.

By sticking to one color, and leaving lots of blank space you can ensure your design doesn’t distract a potential customer from your case study content.

Color combination examples

In this case study on Polygon Media, the design is simple and professional, and the layout allows the prospective customer to follow the flow of information.

The gradient effect on the left-hand column helps break up the white background and adds an interesting visual effect.

Add long term goals in your case study

When creating a case study it’s a great idea to look at both the short term and the long term goals of the company to gain the best understanding possible of the insights they provide.

Short-term goals will be what the company or person hopes to achieve in the next few months, and long-term goals are what the company hopes to achieve in the next few years.

Check out this modern pattern design example of a case study below:

Lead generation business case study template

In this case study example, the short and long-term goals are clearly distinguished by light blue boxes and placed side by side so that they are easy to compare.

Lead generation case study example short term goals

Use a strong introductory paragraph to outline the overall strategy and goals before outlining the specific short-term and long-term goals to help with clarity.

This strategy can also be handy when creating a consulting case study.

Use data to make concrete points about your sales and successes

When conducting any sort of research stats, facts, and figures are like gold dust (aka, really valuable).

Being able to quantify your findings is important to help understand the information fully. Saying sales increased 10% is much more effective than saying sales increased.

In sales case study examples, like this one, the key data and findings can be presented with icons. This contributes to the potential customer’s better understanding of the report.

They can clearly comprehend the information and it shows that the case study has been well researched.

Vibrant Content Marketing Case Study Template

Use emotive, persuasive, or action based language in your marketing case study

Create a compelling case study by using emotive, persuasive and action-based language when customizing your case study template.

Case study example pursuasive language

In this well-written case study example, we can see that phrases such as “Results that Speak Volumes” and “Drive Sales” have been used.

Using persuasive language like you would in a blog post. It helps inspire potential customers to take action now.

Keep your potential customers in mind when creating a customer case study for marketing

82% of marketers use case studies in their marketing  because it’s such an effective tool to help quickly gain customers’ trust and to showcase the potential of your product.

Why are case studies such an important tool in content marketing?

By writing a case study you’re telling potential customers that they can trust you because you’re showing them that other people do.

Not only that, but if you have a SaaS product, business case studies are a great way to show how other people are effectively using your product in their company.

In this case study, Network is demonstrating how their product has been used by Vortex Co. with great success; instantly showing other potential customers that their tool works and is worth using.

Case studies are particularly effective as a sales technique.

A sales case study is like an extended customer testimonial, not only sharing opinions of your product – but showcasing the results you helped your customer achieve.

Make impactful statistics pop in your sales case study

Writing a case study doesn’t mean using text as the only medium for sharing results.

You should use icons to highlight areas of your research that are particularly interesting or relevant, like in this example of a case study:

Coral content marketing case study template.jpg

Icons are a great way to help summarize information quickly and can act as visual cues to help draw the customer’s attention to certain areas of the page.

In some of the business case study examples above, icons are used to represent the impressive areas of growth and are presented in a way that grabs your attention.

Use high contrast shapes and colors to draw attention to key information in your sales case study

Help the key information stand out within your case study by using high contrast shapes and colors.

Use a complementary or contrasting color, or use a shape such as a rectangle or a circle for maximum impact.

Blue case study example case growth

This design has used dark blue rectangles to help separate the information and make it easier to read.

Coupled with icons and strong statistics, this information stands out on the page and is easily digestible and retainable for a potential customer.

Less is often more, and this is especially true when it comes to creating designs. Whilst you want to create a professional-looking, well-written and design case study – there’s no need to overcomplicate things.

These simple case study examples show that smart clean designs and informative content can be an effective way to showcase your successes.

Use colors and fonts to create a professional-looking case study

Business case studies shouldn’t be boring. In fact, they should be beautifully and professionally designed.

This means the normal rules of design apply. Use fonts, colors, and icons to create an interesting and visually appealing case study.

In this case study example, we can see how multiple fonts have been used to help differentiate between the headers and content, as well as complementary colors and eye-catching icons.

Blue Simple Business Case Study Template

Whether you’re a B2B or B2C company, business case studies can be a powerful resource to help with your sales, marketing, and even internal departmental awareness.

Business and business management case studies should encompass strategic insights alongside anecdotal and qualitative findings, like in the business case study examples below.

Conduct a B2B case study by researching the company holistically

When it comes to writing a case study, make sure you approach the company holistically and analyze everything from their social media to their sales.

Think about every avenue your product or service has been of use to your case study company, and ask them about the impact this has had on their wider company goals.

Venngage orange marketing case study example

In business case study examples like the one above, we can see that the company has been thought about holistically simply by the use of icons.

By combining social media icons with icons that show in-person communication we know that this is a well-researched and thorough case study.

This case study report example could also be used within an annual or end-of-year report.

Highlight the key takeaway from your marketing case study

To create a compelling case study, identify the key takeaways from your research. Use catchy language to sum up this information in a sentence, and present this sentence at the top of your page.

This is “at a glance” information and it allows people to gain a top-level understanding of the content immediately. 

Purple SAAS Business Case Study Template

You can use a large, bold, contrasting font to help this information stand out from the page and provide interest.

Learn  how to choose fonts  effectively with our Venngage guide and once you’ve done that.

Upload your fonts and  brand colors  to Venngage using the  My Brand Kit  tool and see them automatically applied to your designs.

The heading is the ideal place to put the most impactful information, as this is the first thing that people will read.

In this example, the stat of “Increase[d] lead quality by 90%” is used as the header. It makes customers want to read more to find out how exactly lead quality was increased by such a massive amount.

Purple SAAS Business Case Study Template Header

If you’re conducting an in-person interview, you could highlight a direct quote or insight provided by your interview subject.

Pick out a catchy sentence or phrase, or the key piece of information your interview subject provided and use that as a way to draw a potential customer in.

Use charts to visualize data in your business case studies

Charts are an excellent way to visualize data and to bring statistics and information to life. Charts make information easier to understand and to illustrate trends or patterns.

Making charts is even easier with Venngage.

In this consulting case study example, we can see that a chart has been used to demonstrate the difference in lead value within the Lead Elves case study.

Adding a chart here helps break up the information and add visual value to the case study. 

Red SAAS Business Case Study Template

Using charts in your case study can also be useful if you’re creating a project management case study.

You could use a Gantt chart or a project timeline to show how you have managed the project successfully.

Use direct quotes to build trust in your marketing case study

To add an extra layer of authenticity you can include a direct quote from your customer within your case study.

According to research from Nielsen , 92% of people will trust a recommendation from a peer and 70% trust recommendations even if they’re from somebody they don’t know.

Case study peer recommendation quote

So if you have a customer or client who can’t stop singing your praises, make sure you get a direct quote from them and include it in your case study.

You can either lift part of the conversation or interview, or you can specifically request a quote. Make sure to ask for permission before using the quote.

Contrast Lead Generation Business Case Study Template

This design uses a bright contrasting speech bubble to show that it includes a direct quote, and helps the quote stand out from the rest of the text.

This will help draw the customer’s attention directly to the quote, in turn influencing them to use your product or service.

Case Study Examples Summary

Once you have created your case study, it’s best practice to update your examples on a regular basis to include up-to-date statistics, data, and information.

You should update your business case study examples often if you are sharing them on your website.

It’s also important that your case study sits within your brand guidelines – find out how Venngage’s My Brand Kit tool can help you create consistently branded case study templates.

Case studies are important marketing tools – but they shouldn’t be the only tool in your toolbox. Content marketing is also a valuable way to earn consumer trust.

Case Study FAQ

Why should you write a case study.

Case studies are an effective marketing technique to engage potential customers and help build trust.

By producing case studies featuring your current clients or customers, you are showcasing how your tool or product can be used. You’re also showing that other people endorse your product.

In addition to being a good way to gather positive testimonials from existing customers , business case studies are good educational resources and can be shared amongst your company or team, and used as a reference for future projects.

How should you write a case study?

To create a great case study, you should think strategically. The first step, before starting your case study research, is to think about what you aim to learn or what you aim to prove.

You might be aiming to learn how a company makes sales or develops a new product. If this is the case, base your questions around this.

23 Case Study Questions Every Marketer Should Ask

Template: 23 Case Study Questions Every Marketer Should Ask

December 16, 2022

By Joe Gillespie

Case studies offer one of the most powerful types of content in the inbound marketer’s toolbox.

When done right—with descriptive storytelling and a powerful visual presentation—a case study can deliver a clinching message to leads in the decision stage of the buyer’s journey . Prospects who already know they need a solution to their problems read the case study and see how your company has helped others, which nudges them closer to becoming customers.

That said, case studies are a different animal from other inbound marketing content, such as blogs , e-books, pillar pages, and infographics. Most content in the awareness and consideration stages of the buyer’s journey doesn’t self-promote much but, instead, simply gives the reader information. The decision stage, however, is a chance to persuade leads that your solution is their best option. 

Shifting gears usually isn’t much of a problem for marketers, but switching to the case study format can be. The process is more journalistic—you conduct interviews, gather information, and weave a narrative—and that can be daunting for someone more accustomed to blogging than article writing.

Don’t stress out: Case studies aren’t difficult if you take your time, are diligent about gathering information and writing the content, and ask the right questions. And we can help with the questions! Below are 23 to ask when conducting the interviews.

Case Study Questions to Ask Your Project Manager

Usually, you will interview someone at your company—maybe a project manager, salesperson, client manager, customer liaison, or other colleague who deals with customers—who worked with the client you are profiling for the case study. 

Often, this interview will occur first and give you a good launching point for subsequent interviews with the customer’s representatives. You might already know the answers, but ask these questions anyway. You may get a deeper explanation from your interview subject and something quotable you can use in the case study.

(Note: I’m using product , solution , and service interchangeably throughout these case study questions; simply use the term that best applies to your company during the actual interviews.)

  • What initial challenges did you encounter with the client that could be overcome with our product? This question is good to establish what problem the customer was experiencing and how your organization was poised to help.
  • What process did you follow during implementation? Again, this may be obvious to you but is worth hearing from the PM. A little bit of process info in your case study can go a long way toward showing leads how you, step by step, can help solve their problem.
  • What roadblocks for implementation did you help the client overcome? Highlighting how you assisted shows that no matter how messy a customer’s status with its previous solution is, you are positioned to overcome the hurdles that get in the way.
  • How have we helped the client since implementation/introduction? Some customers are good to go after your solution is implemented, but others rely on additional support—be sure to find out what that support entails.
  • What kind of success did the client enjoy with our product? Results, results, results!
  • Did we go above and beyond with our service? If the answer to this is no, that’s OK, and perhaps you don’t want to set unreasonable expectations—even if you did go above and beyond—with the case study, which is also fine. That said, showing how you went the extra mile or were unusually innovative stands out to readers looking for a company that will take care of its customers.

Case Study Questions to Ask the Client

If a client has agreed to be the subject of a case study, they obviously are happy with the service you provided. Take advantage of this enthusiasm by asking open-ended questions and letting your interviewee gush about your organization and your solution.

Some of the case study questions listed here may seem redundant to the ones you asked internally, but ask them anyway. You want both perspectives, and often, the best quotes you hear and use will be from the client.

  • Can you give a brief description of your company? If you aren’t familiar with the client, ask for some basic background. Yes, you usually can find such information online, but this is a good icebreaker to get the interviewee talking.
  • How did you first hear about our service? If the client learned about you via other case studies or articles in outside publications or websites—or they simply knew about you by reputation or word of mouth—you definitely want to include that in the case study. For the reader, this info strengthens your industry presence and thought leadership. This question is also a good lead-in to learn about how the deal between the client and your company was finalized.
  • What challenges/problems necessitated a change? Listen carefully to the answer to this question. Ideally, the challenges and problems the client was facing are exactly what your organization’s product addresses.
  • What trends in your industry drove the need to use our product?
  • What were you looking for in a solution?
  • What made our solution stand out over others that you researched? Ideally, you want the interviewee to say how great your product is. This and other questions lead them to be your greatest advocate.
  • What feature of our product was most appealing?
  • How did you implement/introduce our solution? The rollout, and the steps taken to get to that point, can make or break the success of the solution. Ideally, the client will say the process was seamless and that your product and team were the reasons for such ease.
  • How did our team help with implementation?
  • What was the initial reaction to our product? In other words, how did the client’s users and customers accept and utilize the solution?
  • How has our solution helped since implementation? Dig into the success realized by your product. This is important because it provides the basis of the case study: “X Company Used Our Solution and Achieved X Hundred Percent Growth.”
  • Has this solution saved money and/or increased productivity?
  • Can you share any metrics/KPIs that show the success you have enjoyed with our service? The more hard numbers, the better.
  • What have you been most impressed with? Here’s another chance for the client to gush.
  • What surprised you about us? Hopefully, the customer will share the positive unexpected—things that make you stand out amid the competition.
  • What plans do you have to use our solution in the future? After initial success, many companies expand the use of a product, either to more people or additional applications. This info is also important to include in the case study because it shows that the client is not only sticking with your product but also using it to foster more growth and productivity.
  • Is there anything else we should know? If you’ve been thorough, the answer to this is likely no, but the question still offers a chance for the interviewee to conclude.

A case study is a wonderful inbound marketing opportunity for your organization. Ask these questions, and use the answers to write a case study that helps your product and your company shine in the eyes of leads.

20+ Data Science Case Study Interview Questions (with Solutions)

2023 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)

image

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

image

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:

image

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:

case studies questions and answers

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.

Case studies are among the simpler types of research, making them an excellent option for new researchers.

Explanation: Case studies are in-depth analyses of a single person, group, event, or time frame. They cover a variety of qualitative and quantitative research techniques to delve into the underlying ideas behind an event in a practical setting.

Case study research frequently necessitates a comprehensive interpretation.

Explanation: Numerous disciplines employ the case study approach as a "robust research tool, particularly when a comprehensive, in-depth analysis is required."

A case study is a type of research methodology that thoroughly analyzes all the factors that affect a situation.

Explanation: A case study is an in-depth examination of a particular subject, such as a person, group, location, occasion, business, or phenomena. In social, educational, clinical, and business research, case studies are frequently used. Although quantitative methods are occasionally utilized, qualitative methods are typically used in case study research designs.

A particular kind of case study is the critical instance.

Explanation: Case studies are utilized in critical cases to ascertain an event's source and effects. The primary goal of this kind of case study is to examine one or more sources with specialized interest, and occasionally with no interest at all. A critical case study might be employed to contest a generalization.

A thick description is one that covers every facet of the subject in great detail.

Explanation: Thick description is a qualitative research method used in the social sciences that provides in-depth descriptions and interpretations of circumstances that the researcher has observed. It is a qualitative and ethnographic research method. Gilbert Ryle and Clifford Geertz, two social anthropologists, coined the phrase.

Research questions for case studies typically start with HOW or WHY.

Explanation: The "why" or "how" in case study questions usually refers to the circumstances and occurrences in the case study. Because it may establish the prior research and generate questions by acquiring additional information, a literature review aids in the formulation of case study questions.

Typically, case studies collect quantitative data.

Explanation: The data gathered for case study research are often qualitative (words, meanings, and perspectives), but they can also be quantitative (descriptive numbers, tables). The creation and evaluation of theories may benefit from qualitative data analysis. The grounded theory method may be used while developing theories.

Case Study Analysis 

The London 2012 Olympic Games

1) What are the tradeoffs that Williamson faces?

2) How might his pricing strategy vary by sport? Please focus on three sports - swimming, indoor track cycling and table tennis. How should ticket prices and price ranges differ across these sports? 3) Does it matter that Olympics are a one-time event? Why or why not? 4) If you could, what would you recommend to Williamson and LOCOG?

Answer & Explanation

1) Williamson faces a delicate balancing act in the tradeoffs associated with ticket pricing for the London 2012 Olympic Games. On one hand, he must set prices at a level that maximizes revenue, considering factors like demand and market dynamics. On the other hand, he needs to ensure that ticket prices are accessible to a broad audience to uphold the inclusive spirit of the Olympic Games. Striking this balance is crucial for the overall success of the event, as excessively high prices may hinder attendance, while excessively low prices may compromise potential revenue.

2) The pricing strategy employed by Williamson should be tailored to the unique characteristics of each sport, with a focus on swimming, indoor track cycling, and table tennis. For high-profile sports like swimming, where demand is likely to be substantial, a premium pricing approach could be justified. Conversely, sports like table tennis, which may have a broader but potentially less fervent audience, might benefit from more affordable ticket options. Indoor track cycling could fall somewhere in between, with pricing reflecting a balance between demand and audience engagement.

3) The one-time nature of the Olympics introduces a distinctive set of challenges and opportunities for Williamson and LOCOG. While the scarcity of the event could theoretically allow for higher ticket prices due to heightened demand, it also necessitates a cautious approach. The ephemeral nature of the Olympics means that any missteps in pricing could lead to public backlash, potentially tarnishing the legacy and public perception of the Games. Therefore, it is crucial to consider the long-term impact of pricing decisions on the event's reputation and legacy.

4) A comprehensive recommendation for Williamson and LOCOG would involve a multifaceted approach. Firstly, conduct thorough market research to understand the nuanced demand patterns for each sport. Implement dynamic pricing strategies that allow for real-time adjustments based on demand fluctuations, ensuring optimal revenue generation. Introduce tiered pricing structures to cater to diverse audience segments, striking a balance between affordability and premium options. Consider creating bundled ticket packages for multiple events to encourage cross-sport attendance. Ultimately, the goal should be to enhance accessibility for a broad audience while maximizing the revenue potential of this unique one-time event.
