Deloitte Case Interview Guide 2023: Criteria, Technique & Tips

Deloitte is one of the “ Big Four ” – the world's four largest accounting and consulting firms. Competitive recruitment processes aside, successful candidates must pass through challenging consulting interviews called “ Case Interviews ”.

In this article, you will be guided through the building blocks of Deloitte’s Case Interviews, with special tips, techniques, examples, and more!

Overview of Deloitte case interview

Deloitte case interviews are often candidate-led . The candidate will be leading or taking control of every step ahead to solve the case. This includes structuring the problem, drawing frameworks, asking for data, synthesizing findings, and proposing solutions. 

The Deloitte case interview occurs in the last stages of Deloitte’s recruitment process. Candidates will encounter two Deloitte case interview types: individual case interview and group case interview.

What does Deloitte look for in candidates?

During the Deloitte case interviews, candidates are expected to demonstrate three crucial traits of a consultant: problem-solving skills, analytical ability, and strategic and logical thinking. 

Problem-solving skills: The point of hiring consultants is that they can break down business problems better than anyone else. The entire consulting industry rests on consultants' unique analytical problem-solving abilities.

Analytical ability: Strong analytical ability enables consultants to analyze complex business problems and generate meaningful insights. They can apply these skills to break down problems by identifying patterns, trends, and root causes, making them more manageable and easier to tackle. 

Strategic and logical thinking: Strategic and logical thinking enables consultants to make informed decisions, anticipate future change, and navigate complex business landscapes to deliver optimal solutions for their clients.

Deloitte case interviews occur in the last stage of the recruitment process

Deloitte recruitment process consists of three main stages: (1) online application, (2) online tests, and (3) interviews .

The whole process can take up to 2-3 months, for a job starting 6-12 months after application. Newer offices can speed up the process to meet the demands.

Online Application: The most important thing in this first stage is to prepare an outstanding consulting-style resume. Our free consulting resume templates helped thousands of candidates reach their consultant dream.

Online Tests: As part of the online application, you will have to sit through five tests. These include: Cognitive Test, Verbal Reasoning Ability Test , Numerical Reasoning Ability Test , Logical Reasoning Ability Test , and Psychometric Questionnaire.

Interviews: The candidate will go through two interview rounds. The first round will generally be a phone screen/face-to-face initial interview with a Talent Acquisition team member. The second round will be individual and group case interviews. The number of interviews depends on the service line and position candidates apply for.

In Deloitte case interviews, candidates usually have to go through one or two 30-60 minute individual case interviews and one 1-hour group case interview.

Deloitte individual and group case interview

Deloitte individual case interview is the standard type of case interview. Candidates will receive the case from the interviewer, which they need to define the issue and give solutions. Usually, there will be two cases for a 45-60 minutes session.

Deloitte group case interview is similar to other group case interviews at BCG, Bain, and three other Big Four firms. A group case interview will usually go through five stages:

Stage 1: You will be assigned to a group of 3–6 applicants.

Stage 2: The group will be given a case and relevant information to solve.

Stage 3: You will be given 10 minutes to examine the case and prepare alone or in collaboration with another team member.

Stage 4: The group will discuss case questions for 20 minutes while the interviewers observe and take notes.

Stage 5: The interviewers will ask questions about the cases in the next 20 minutes.

Deloitte case interview format is candidate-led

The Deloitte case interview is often a candidate-led case interview . The interviewer will present the issue and require the applicant to lead and control every stage to solve the case: structure the problem, develop frameworks, request data, synthesize results, and provide solutions.

Candidate-led cases focus on one big problem

In candidate-led cases, you have to figure out how to solve a big case . This is opposed to interviewer-led cases , where the interviewer presents smaller questions about the case to the candidate.

You should take a top-down approach - break the problem into small parts of the issue tree and tackle each one at a time. 

Candidate-led cases are flexible

In a candidate-led interview, the candidate can choose their own suitable approach.

The interviewer usually forms a “universe” of data on the client and their problems for you to explore. If your issue trees and solutions seem to go beyond the given information (in a good direction), the interviewer can “make up” new information on the spot to help you solve the case in your way.

Candidate-led cases focus less on being right

In a candidate-led interview, you put less emphasis on giving a definite “correct” answer and focus more on creating a structured, reasonable approach .

An “acceptable” margin of error is allowed in the candidate-led interview since you must break down the problems by yourself without much assistance from the interviewer.

Fundamental framework to solve Deloitte case interview

To solve the Deloitte case interview, you need to develop an issue tree to break down your case. To create a suitable issue tree, you can use common frameworks for case interviews: Profitability framework, Business situation framework, McKinsey M&A framework, 4P/7P marketing mix, and Porter’s five forces model. 

To further enhance your case interview performance, you can apply five effective tools (or mini-frameworks): External vs. Internal, Quantitative vs. Qualitative, Costs vs. Benefits, 2x2 Matrix, and SWOT analysis. 

Five common frameworks for case interview

Profitability framework is mostly used to mathematically break down problems before switching to the qualitative framework for solutions. To use the profitability framework, candidates will split profits into revenues and costs.

Business situation framework is used to analyze a company situation in four areas - Company, Competitor, Customer, and Products (3C-1P). This 3C-1P framework is flexible for many purposes; however, it may be too generic and need customization depending on the situation. 

McKinsey M&A framework is used to assess a proposed merger and/or acquisition on three aspects: standalone values of each involved company, their synergy, and other factors. This framework is MECE and promotes customizations, and is one of the best M&A frameworks. 

4P/7P marketing mix in marketing for tangible work analyzes the 4P - Product, Price, Place, and Promotion; while in service marketing, three other Ps will be added in - People, Process, and Physical evidence. This framework focuses on the marketing aspect, hence unsuitable for multi-function strategies. 

Porter’s five forces model analyzes the industry surrounding a business in five aspects - Suppliers, Customers, Competitors, New entrants, and Substitutes. This framework is used to get an industry overview and understand the client’s context.

Five effective tools for case interview

External vs. Internal method is quick and easy to segment information about a particular entity. The internal branch concerns what is inside or intrinsic to the entity, and the external branch concerns outside factors. 

Qualitative vs. Quantitative mini-framework is used for evaluations. Dividing items into two MECE groups reduces confusion and minimizes the risk of missing an essential item. 

Cost vs. Benefit in the decision-making process is very straightforward - if the benefits of an option outweigh its costs, that option can be chosen.

2x2 Matrix is a decision-making tool where options are examined using two criteria, each forming an axis of the matrix. 

SWOT analysis mini-framework is seldom used in case interviews for being too generic. However, it can be used to evaluate a company’s positioning within the industry context quickly. 

You can check our free article on Case Interview Framework to understand the common framework used in the case interview.

How to Prepare for Deloitte Case Interviews

Step 1: Familiarize with interviewer-led case examples

Deloitte has several sample cases on its website with guides and tips. You can also examine examples of similar candidate-led case interviews from BCG and Bain to familiarize yourself with the case flow and how to interact with the interviewer.

Step 2: Practice consulting math

Consultants work with quantitative data dozens of times a day. Pulling out a calculator every time they need to calculate something takes too long, and doing so in negotiations looks terrible.

This is why interviewers place such high emphasis on the mental math skills of prospective consultants.

In the beginning, consulting math can be difficult for some; nonetheless, I have a few tips for you to ease the process and still practice effectively:

Use Your Head: Do all your daily calculations mentally unless an EXACT answer is required.

Flatten the Learning Curve: At the start, scratch paper and a 5% margin of error help; once you are confident, discard the paper and narrow down the margin.

Establish a routine: Allocate some time for daily practice. This may seem hard at first, but you can feel the improvement once you’ve overcome the inertia.

Step 3: Develop Business Intuition

Having business intuition significantly sharpens your performance in case interviews.

Working on intuition is a gradual process that takes practice every day. You can improve your business intuition in two ways:

Written Sources: I suggest reading business papers daily; you can also visit McKinsey, Bain, and BCG websites for their excellent articles. Beware though – it’s not the pages you read that count, but the insights you draw from them.

First-hand Experience and Observations: Don’t just come to your workplace to work; examine what senior managers are doing – what’s the rationale for their decision, and how has it impacted the organization?

Step 4: Learn the fundamentals and frameworks

Practice using hypotheses and issue trees , the MECE principle , and the frameworks until you are comfortable using them– they are the backbone of candidate-led case interviews.

It might be tempting at first to go straight for the frameworks – if you make this common mistake, prepare for some unpleasant surprises in the interview. Frameworks need a lot of customizations to fit with real cases, and to customize effectively, you need that fundamental knowledge.

Of course, don’t draw an issue tree for all your daily problems – that’s just overkill, but remember to take a structured approach and picture an issue tree in your head while searching for your keys.

Step 5: Perform mock interviews

The best way to get good at something is to do it.

Best to find yourself a former consultant to help you practice; they’ve been through countless case interviews, both real and mock, and they know what’s required of a candidate, so they’re the best people to run your simulations with.

Study your cases down to the smallest details. Replay them repeatedly, take notes of the interviewer’s feedback, and look for other areas you can improve.

Tips for the perfect Deloitte case interview

Nine tips for the perfect deloitte individual case interview.

Tip #1: Understand the procedure of a candidate-led case interview

There is a five-step procedure to approach the PwC candidate-led case interview. 

Taking the case: You need to take notes on all information regarding the clients and the case situation. Keep your notes organized to refer back to them easier.

Clarifying: You will have time to gain more information and/or clarify the points you haven’t fully understood about the cases.

Structuring: You will need to break down the case business problem into smaller components to create the issue tree , allowing you to solve it in an effective and cohesive manner.

Hypothesizing: You must develop the hypothesis based on evidence and available data about the problems and find the root cause. If the initial hypothesis in a branch of the issue tree no longer makes sense, go to the next branch. If the hypothesis matches, stick to it to find the root causes and solutions.

Pitching: The pitch is your case interview's final product, where you summarize all findings and recommendations to solve the case. You need to deliver the pitch in a structured, top-down manner.

Tip #2: Have a perfect case opening

There are four reasons to make a good case opening while you deliver your case interview:

First, it shows you have complete control of the upcoming problem-solving process, which is critical in candidate-led cases.

Second, you can demonstrate your whole leadership and relationships with proactiveness - aligning yourself with PwC's five qualities mentioned above.

Third, a good case opening creates a great first impression. Consultants are expected to perfect everything from the beginning to the end, so this could make a good head start for a 30-minute interview.

Finally, this is an opportunity to align during the interview. After the interviewer has outlined the case details, explain the case to the interviewer in your own words to ensure you grasp the issue and align with the interviewer.

Tip #3: Map your next moves

Pause occasionally to summarize where you are and where you’re going next. It gives you a sense of direction and authority; additionally, you get plus points in the interview for an organized approach. 

This also gives your interviewer a chance to help you with your mistake. If your interviewer gives you advice, take it – assume it’s intended to be helpful.

Tip #4: Be consistent with your intended hypotheses

Always speak with the current hypothesis in mind, and that hypothesis must be in the issue tree. The sole purpose of the hypothesis-driven approach is to have your efforts and problem-solving steps guided and structured. 

Therefore, to avoid being overwhelmed by piles of data in your case interview, do a sanity check by returning to your issue tree. If your action does not correspond to your present place on it, go back immediately!

Tip #5: Deliver your pitch in one structured manner

This is the most important tip because you need to show that you own the consultant qualities - being structured and straight to the point. Present your analyses in a perfect, insightful, top-down, concise, and captivating final pitch.

Find a way to structure the problem; this will guide your discussion with the interviewer. Briefly explain the framework you plan to use, allowing the interviewer to comment. In general, the simpler the framework, the better. Once the interviewer endorses your framework, stick to it.

To structure your speech:

Begin with a summary line that states the key takeaway/intention.

Separate what you want to say into distinct sections. As much as possible, avoid jumping back and forth between items.

Number your items so you and your interviewer can keep track of them. It's even better to specify how many things you'll be discussing beforehand.

Make your recommendation based on the conclusions you reached from your discussion, even if you are unsure with so little data and time to discuss all the issues.

Tip #6: Make a personalized script

Make a script of what you will say and rehearse it a hundred times. Practice all of the formulaic phrases, such as the opening or data request. With enough practice, those lines will become second nature to you.

The secret to seeming professional in a case interview is to talk in a systematic and formal manner. Using scripts also saves brainpower, which you will undoubtedly want in case interviews.

Tip #7: Keep your notes organized

Neat note-taking greatly assists with your train of thought, making storing and organizing information easier. You're also demonstrating to the interviewer that you're well-organized and meticulous.

Divide your notes into three categories to make them easier to read and interpret: data, presentation, and scratch paper. When the interview begins, take three pieces of paper and name them appropriately. Here is the content that should be on each type of note:

Datasheet: note down and process any data the interviewer gives you and your calculations.

Presentation sheets: draft things you’ll say to the interviewer.

Scratch paper: anything else you need to write, such as brainstorming ideas.

Tip #8: Avoid long pauses

Take a minute to think; don't be afraid of the silence. If you need silence to think, ask for a timeout or announce think-out-loud mode.

However, taking it too long will backfire, especially if you can’t come up with something worthy of the long wait. Use the pause prudently, and always try to think as fast as possible while still being “correct”. 

Tip #9: Find and ask for more insights

Try your best to be in-depth and comprehensive with your analysis. Always ask yourself, “Am I overlooking something?” and “Can I drill down further?”. 

This is also helpful when you are stuck in your analysis. You can try asking for insights from the interviewer (remember to state your purpose clearly) like this:

If you have a piece of data and don’t know what to make of it, ask for benchmarks to put the data into perspective.

If you are unsure which framework to employ, consider "segmentation" - look at how the customer or the industry often segments that item. If you need to know how they do it, ask the interviewer.

When you cannot see the problems in the case (probably resulting from the “MECE” of your issue tree), ask the interviewer nicely for a way out.

However, remember to manage your time well. If you take too long, the interviewer might force you to move on, and you will lose the time to solve the case holistically.

Four tips for the perfect Deloitte group case interview

You are being evaluated with many other candidates in group case interviews. So, how can you make yourself stand out? Here are six helpful recommendations to ace a group case interview.

Tip #1: Manage your ideas

Take your time processing the question and developing an orderly and structured response. If you allow yourself time to analyze, your answer will be more robust.

Ask the interviewer for a few minutes to organize your thoughts, but avoid excessive silence when necessary.

Try not to intervene forcefully while others are speaking in group interviews. If you have a brilliant idea, write it down. That way, the flash of brightness won't fade from your memory.

Tip #2: Decide whether your role is a leader or team member.

This is the decision that needs to be made on the spot - other candidates are going for the “leadership role” of the discussion. If you want to lead, go right at it. However, you can still demonstrate desirable consultant qualities even as a team member.

If you decide to be the team leader, emphasize your facilitator role.

It’s a good idea to be proactive in proposing what topics to discuss, in what order they should be addressed, and how much time should be allocated to each issue. You can bring the group’s focus back together if the group gets off track.

By the end of the group discussion, make a point to compile people's different points. This puts you in a position to bring everyone together and ensure all candidates are on the same page.

If you decide to be a team member, speak to add value.

Candidates will take turns presenting answers to the interviewer. Before it’s your turn, listen carefully to other people’s answers and the interviewer’s feedback.

This way, you can add valuable and helpful insights to the discussion. Remember, good points go to the quality of what you say, not the number of times you speak up.

Tip #3: Ask good questions

Asking outstanding questions will set you apart. It demonstrates that you are attentive and willing to learn more. Great questions often target one or more objectives: explaining an unfamiliar term, clarifying the issue's purpose, or expanding the team's understanding of the setting or business.

Tip #4: View others as teammates

Seeing people as colleagues puts you in a collaborative attitude, which allows you to work successfully with others. You look to be both a helpful leader and a team player in this manner.

You can be the first to answer your interviewer's question to avoid seeming timid. You can encourage co-interviewees by emphasizing their excellent ideas, adding what you believe is lacking, and explaining your reasoning.

1. deloitte consulting is bigger than mckinsey + bcg.

Deloitte is a force to reckon with in consulting. In 2022, it generated ~$26bn in revenue from its consulting business line. This makes it about as big as McKinsey, Bain and BCG combined.

Deloitte Consulting grew through a series of acquisitions. As a result, it's a collection of relatively independent firms operating under the Deloitte Consulting umbrella. Each member firm is managed by local partners who are responsible for their P&L. This is why you get more variation across different offices and regions than you do at a firm such as McKinsey.

Deloitte Consulting has three main practice groups you need to be aware of when applying:

1. Strategy and Operations (S&O) focuses on topics such as corporate strategy, supply-chain improvement, business model transformation, process improvements, etc.

2. Technology consulting focuses on digital strategy, delivery of IT programmes, cyber risks management, designing and building tech-based solutions for clients, etc.

3. Human capital focuses on topics such as organisation transformation, change management, corporate learning and development, diversity and inclusion, etc. See Also Working at Deloitte: Job Opportunities and Application Tips Unlocking Success at Deloitte: A Deep Dive into the Hiring Process

In 2013, Deloitte acquired Monitor which was initially founded by Michael Porter, the father of Porter's five forces . Monitor is now part of Deloitte S&O and that brand is particularly strong in North America.

The type of work Deloitte S&O does is very similar to what you would do at McKinsey , BCG or Bain . If you'd like to learn more about how Deloitte (and the other Big 4 firms) compares to the MBB firms, check out our MBB vs. Big 4 guide .

2. Deloitte interview process

Your interview process with Deloitte will depend on whether you're applying as an experienced or early career candidate. There is also some variation by country, so we recommend that you ask your local HR contact at Deloitte for more details.

Below is an outline of the most common interview process and will be correct for the majority of candidates.

2.1 Early career candidates

As an early career candidate you can apply online. You'll need your educational qualifications to hand, and you'll need to meet the minimum requirements.

The next step is an "immersive online assessment". Here you'll be asked to look at work scenarios and answer how you would respond.

Once you've completed it, you'll receive a "bespoke feedback report about your strengths and abilities".

If you fail the assessment, you'll hear back within a couple of days, but if you pass it may take a week or two before Deloitte contacts you - so in this case, no news is good news!

If you pass, you'll go onto the next assessment step: the "job simulation". You’ll answer questions across formats that include writing, video, multiple choice and ranking. Make sure you're dressed correctly and are in a quiet place before starting the simulation.

After you’ve completed the simulation, you'll get an email letting you know how you did within four weeks.

If successful you would then have a "Final stage assessment", which is a video interview with a senior consultant or an online group exercise. This would be the last step in your interview process.

Click here for more information on the interview process for early career applicants.

2.2 Non-early career candidates

If you're an experienced candidate, or at least not an undergraduate or recent graduate, the interview process will probably consist of three steps:

• Resume and cover letter screening
• First round interviews
• Second round interviews

2.2.1 Resume and cover letter screening

First, recruiters will look at your resume and assess if your experience matches the open position. This is the most competitive step in the process—we’ve found that 90% of candidates don’t make it past this stage.

You can use this free resume guide and this free cover letter guide to help tailor yourapplication to the position you’re targeting.

And if you’re looking for expert feedback, you can also get input from our team of ex-MBB recruiters , who will cover what achievements to focus on (or ignore), how to fine tune your bullet points, and more.

2.2.2 First round interviews

Your interviewers at Deloitte will consist of a mix of senior consultants, managers and partners. First round interviews may be done in person or via video or phone call. They usually consist of:

• one behavioural interview (30 to 45mins)
• one or two case interviews (30 to 45mins each).

This is quite similar to what you could expect at other consulting firms.

2.2.3 Second round interviews

Second round interviews are similar to first round interviews, though the line of questioning can be a bit tougher. Your final interview is usually with a hiring partner, and before that you may face a group case interview.

• One behavioral interview (30 to 45mins)
• One case interview (30 to 45mins)
• One group case interview (45mins - 1hr)

Now you've seen an overview of the interview process, let's take a detailed look at regular case interviews and group case interviews at Deloitte, and how you should prepare for them.

3. Deloitte case interview questions

Case interviews at Deloitte are candidate-led. The style is therefore similar to what you will experience in a BCG case interview or a Bain case interview . Our research and experience tells us that there 7 types of questions you need to prepare for in candidate-led case interviews:

• Framework development
• Framework exploration
• Quant question – Data provided
• Quant question – No data provided
• Creativity question
• Recommendation

You can learn more about case interviews and how to prepare in our free case interview guide . One unique thing about Deloitte case interviews is that they will occasionally (but not always) give candidates written materials and a few minutes to review before they start the interview. This type of scenario requires the kind of skills you could learn in our free written case interview guide .

Deloitte has produced some very useful material to help candidates prepare. Take a good look through this practice case .

Deloitte has also shared some example case studies that you can work through interactively:

• Deloitte case study 1: Federal health agency needs to respond to Ebola epidemic (Advanced)
• Deloitte case study 2: Talent management for the Civil Cargo Protection Bureau (Advanced)
• Deloitte case study 3: Engagement strategy for a huge federal agency (Undergraduate)
• Deloitte case study 4: Recreation Unlimited, a global apparel and sportswear company, must reverse declining market share (Undergraduate)
• Deloitte case study 5: Federal benefits provider needs to formulate its 10-year vision (Undergraduate)

All these strategy cases can all be found on Deloitte's case interview prep tool, along with some Application Program Analyst cases and Business Technology Solution cases.

4. Deloitte group case interview

As mentioned above, Deloitte also uses group case interviews in its final round. Here is the key information you need to be aware of for this interview format:

• Candidates get divided into groups of 4 to 6
• Each group is given information about a case (i.e. a client facing a problem)
• You are given 10mins to review the materials by yourself or with another person in your group
• You are then asked to discuss a few questions about the case for 20mins with the rest of your group in front of your interviewers
• The interviewers will ask a few questions to the group for 15 to 20mins

This type of case mainly tests your ability to work with others. Interviewers won't intervene during the group discussion. They will just observe the group dynamics and mark each participant based on how they are contributing to the discussion.

Here are the top 3 things you should aim to do in your Deloitte group interview:

• Speak with a purpose. At the beginning of a group discussion, a lot of candidates will want to speak their mind as they know participating is important. But participating is not enough. The QUALITY of your input is crucial. Sometimes, it's better to let two or three people get the discussion started. And to then make a very thoughtful point based on how they started the discussion. Focus on the quality of your input, not the quantity.
• Involve everyone. Another tip that's easy to apply is to keep an eye on who's participating in the conversation and who's not. If you identify a member of the group who's struggling to make themselves heard, you should not hesitate to help them be heard by saying something like: "We haven't heard everyone's opinion on this yet. John, Rebecca what do you think?"
• Summarise. Finally, at the end of the 20 minutes group discussion it's a good idea to summarise the different points people have made. This will position you as the person bringing everyone together and making sure all candidates are on the same page. It is something some partners in consulting like doing with clients in real life and will therefore reflect positively on you.

And the top 3 things you should really avoid doing :

• Looking nervous. Group interviews is the time to put your poker face on. Everyone is stressed in a group interview. But you need to try your best to come across as confident. A good way to do this is to focus on basic body language: look at people in the eye, sit confidently, don't cross your arms, etc.
• Interrupting others. Consultants need to be client-friendly, and interrupting someone in a discussion is not client-friendly at all. You should listen carefully to what others are saying. Try to have a genuine interest in what they think. Before making your point, summarise their point to show that you understand what they mean.
• Dominating the conversation. Finally, some candidates are so eager to participate in the conversation that they end up completely dominating the rest of the group without realising it. A good tip to avoid this is to keep an eye on how much time you talk. If you are in a 5-person group you should aim to speak 20% (1/5th) of the time and really no more than 25%.

Your performance in regular and group case interviews will play a big role in Deloitte's decision to give you an offer. If you'd like to learn more how to approach group interviews, check-out our separate detailed guide to group case interviews.

5. Deloitte behavioral questions

Behavioural interview questions asked at Deloitte fall into two categories:

• Fitquestions. These are generic questions such as “ Why consulting? ” or “ Why Deloitte? ”.
• Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you led a team through a difficult situation.” Or “Tell me about a time where you had to manage a team conflict”

Here are the top 5 fit and PEI questions you should prepare for at Deloitte and other consulting firms.

Top 5 fit questions:

• Why Deloitte?
• Why consulting?
• Walk me through your resume
• Tell me about something not on your resume
• Tell me about your greatest accomplishment

Top 5 PEI questions. Tell me about a time when ...

• You led a team through a difficult situation
• You worked in a team and had to manage a conflict
• You had a disagreement with a colleague / boss
• You had to change someone's / a group's mind
• You overcame a really difficult challenge

Don't fall into the trap of under-preparing for these types of questions. While they may seem easier than the case interviews, they are extremely important to get right.

You’ll need to prepare several ”stories” or “examples” from your personal and professional experience to demonstrate that you have the traits that Deloitte is looking for.

To learn more, check out our guide to consulting fit / PEI questions .

6. Deloitte case interview preparation plan

Now that you know what to expect in Deloitte interviews, let's discuss thesteps you should take to prepare.

6.1 Learn the case interview essentials

The best starting point for your case interview prep is our case interview prep guide . It'll take you through all the different types of questions you may be asked in your case interview, show you how to draw from different frameworks to structure your answer, and give you example cases to practise with.

6.2 Become really confident at maths

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. However, during your Deloitte interviews, you will be expected to quickly perform accurate mental maths.

In order to do this, it’s essential to know the formulas for common metrics, like return on investment or breakeven point. And it’s also helpful to know a few maths shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths .

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

6.3 Research the company

Deloitte interviewers want to hire candidates who are deeply motivated to work for their firm. Make sure you're up to date in the latest developments in the area of the company you're applying to join. Here are some useful links to get you started:

• Deloitte's insights page
• Deloitte's selection of business podcasts
• Financial Times' news articles on Deloitte

In addition, do some networking so that you can show you've made the effort to reach out to current staff.

6.4 Do mock interviews

How you solve each case is important, but your interviewers will also be evaluating how you COMMUNICATE your answers. It's important to speak in a structured way that makes it easy to clearly understand your points.

The best way to hone your communication skills is to practise interviewing out loud, and you can do that in three main ways:

• Interview yourself (out loud)
• Practise interviewing with friends or family
• Practise interviewing with ex-interviewers

To help you with this process, here is a broad list of consulting interview questions you can practice with. Practising by yourself is a great way to get started, and can help you get more comfortable with the flow of a case interview. However, this type of practice won’t prepare you for realistic interview conditions.

After getting some practice on your own, you should find someone who can do a mock interview with you, like a friend or family member.

We’d also recommend that you practise 1-1 with ex-interviewers from Deloitte . This is the best way to replicate the conditions of a real case interview, and to get feedback from someone who understands the process extremely well. Meet our Deloitte ex-interviewers who’d love to work with you.

Deloitte Case Interview Prep: Everything You Need to Know (2023)

Deloitte interviews are comprised of case interviews, a group case interview, and behavioral or fit interview questions. In this article, we’ll cover exactly what to expect in your upcoming Deloitte interview and how to best answer all of the different types of questions you may be asked.

Although most case interviews follow a similar structure, each consulting firm runs their interviews in a slightly different way.

We’ll cover in detail:

• The Deloitte interview process
• The 5 steps to solving Deloitte case interviews or case study interviews
• The 3 types of Deloitte case interviews
• 6 examples of Deloitte cases
• 8 Deloitte case interview tips
• How to ace the Deloitte group case interview
• The 10 most common Deloitte behavioral and fit interview questions

Deloitte Interview Process

Deloitte is a massive company with over $46B in annual revenue, with about 40% of that coming from their consulting practice. They are the largest and arguably most prestigious firm of the Big Four. Some consider Deloitte to be the next best consulting firm after McKinsey, BCG, and Bain.

Given its size, Deloitte interviews may vary depending on the country of the office that you are interviewing for. However, the most common interview process consists of two rounds of interviews.

In the first round of interviews, you will have one 30 to 45-minute behavioral interview and one or two 30 to 45-minute case interviews.

In the second or final round of interviews, you will have a 30 to 45-minute behavioral interview, a 30 to 45-minute case interview, and a one hour group case interview.

We’ll cover exactly how to answer each of these types of interview questions in the following sections.

Deloitte Case interview

Deloitte case interviews are candidate-led. You will be in the driver’s seat of the case interview and will be expected to ask the right questions, probe for data, and propose each next step to solve the case.

In a Deloitte case interview, you are not assessed on whether or not you have the correct answer. Instead, Deloitte uses case interviews to assess six different qualities:

• Problem solving : Can you decompose a problem into smaller, more manageable questions?
• Analytical ability : Can you draw the right insights from data and information?
• Strategic thinking : Do you have a sharp business acumen and practical business judgment?
• Logical thinking : Are you structured, organized, and rational in the way that you think?
• Creativity : Can you generate interesting or unique ideas and solutions?
• Professional demeanor : Are you calm, confident, and articulate?

The Five Steps to Solve a Deloitte Case Interview

Deloitte recommends taking these five steps to solve a case interview:

1. Understand the issue and ask clarifying questions

The most important part of the case interview is to make sure you understand the business issue and the objective of the case. The quickest way to fail a case interview is to answer or address the wrong business problem.

Therefore, if either the business issue or objective of the case is unclear, make sure to ask clarifying questions.

2. Identify the underlying assumptions

Next, you’ll need to decompose the overall business problem into smaller, more manageable issues. Identify what would need to be true in order for you to recommend a particular course of action.

To do this, it will be helpful to put together a framework, which is a tool that helps you organize your ideas and thoughts into different categories. To learn how to create outstanding frameworks, review this comprehensive case interview framework guide .

3. Summarize specific issues and findings

Afterwards, you’ll begin investigating different issues or areas of your framework. After investigating each one, it is important that you summarize the key takeaways or insights that you uncovered.

Connect these findings back to the overall business problem and explain how your findings impact your potential recommendation.

4. State your recommendations

Once you have gathered enough evidence and support for your recommendation, you will need to present your recommendation in a clear and concise way.

Start by giving a firm recommendation. Then, provide the three major reasons that support your recommendation. This should summarize most of the important findings from the case.

5. Outline next steps and the expected results or impact

After delivering a recommendation, you should propose potential next steps that you would take if you had more time or data. What would you need to know to further strengthen your recommendation or make you more confident in your answer?

You can also talk about the expected results or impact of your recommendation. This may also have implications on potential next steps, such as analyzing the risks or quantifying the financial benefits.

Types of Deloitte Cases

Deloitte consulting is broken down into three groups:

• Strategy & Operations : primarily focused on corporate strategy, supply-chain improvement, business model transformation, and process improvements. The work that this group does is most similar to the work that McKinsey, BCG, and Bain do
• Technology : primarily focused on digital strategy, delivery of information technology programs, and building tech-based solutions for clients
• Human Capital : primarily focused on organization transformation, change management, corporate learning and development, and diversity and inclusion

The type of case that you get depends on what group you are interviewing with.

For example, If you are interviewing with the Strategy & Operations group, you’ll get a strategy or operations case. If you are interviewing with the Technology group, you’ll get a technology or IT case.

Deloitte Practice Cases

Below are practice cases created by Deloitte. We recommend working through these so that you know exactly what to expect in your Deloitte case interview.

Strategy & Operations cases:

• Retail strategy practice case : Business strategy case focused on helping a warehouse club retailer decide between two different business models. This case provides great practice for interpreting charts and graphs and practicing case math.
• Finance strategy practice case : Non-profit case focused on helping a Federal Health Agency manage the financial activities related to eliminating Ebola.
• Extreme Athletes World Games practice case : General business strategy case focused on helping an Organizing Board develop a strategic plan for hosting the Extreme Athlete World Summer Games.
• Footloose practice case : Strategy case focused on helping a footwear company decide whether to focus on growing in the work boot sector of the market or the casual boot sector of the market. This case provides great practice for interpreting multiple different pieces of data simultaneously.

Technology cases:

• Green Apron practice case : Operations case focused on helping a grocery chain redesign and implement a new e-commerce platform

Human capital cases:

• Technology Institute of the West practice case : Post-merger integration case focused on helping an educational institution realign employee and leadership roles after merging six sister institutions.

Deloitte Case Interview Tips

Deloitte provides the eight tips below to help you improve your case interview performance.

Tip #1: Take notes

While the interviewer is providing you with the case background information, take notes on the most important pieces of information. Pay particularly close attention to the context, company, and case objective.

Tip #2: Make sure you understand the case question

Answering or addressing the wrong business problem is the quickest way to fail a case interview. The most important thing is understanding what the business issue is and what overall question you’ll be expected to answer at the end of the case.

Tip #3: Ask questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case.

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the context or company.

Tip #4: After you develop a framework, develop an initial hypothesis

A hypothesis is an educated guess on the answer based on the data and information that you have so far. It helps guide your analysis and keeps you on the right track.

After developing a framework, try to develop a hypothesis to help you decide what area of your framework you should explore first.

Tip #5: Take time to structure your thoughts

When asked a question in a case interview, don’t always start answering immediately. Instead, take the time to process the question and develop an organized and structured way to answer it. It is acceptable to ask the interview for a brief moment to collect your thoughts.

Your answer will likely be much stronger if you give yourself time to think.

Tip #6: Present a clear, logical story for your recommendation

Remember that consultants need to convince clients to follow their proposed recommendations. Being articulate and persuasive are necessary skills for consultants.

When you deliver your recommendation, try to make it a coherent story. This will make your recommendation easier to follow and more compelling.

Tip #7: Walk the interviewer through your thinking and explain assumptions

You do not get any points for the ideas and thinking that you do not communicate. Therefore, you should make every effort to talk through your thoughts out loud.

Walk the interviewer through what you are thinking. Explain why you have made particular decisions. State your assumptions. This makes it easier for the interviewer to provide feedback or hints to help you out.

Tip #8: Engage the interviewer in a business conversation

Remember that a case interview is a collaborative exercise. You should not be dismissing the feedback and suggestions that the interviewer provides you. They may be trying to help steer the case in the right direction or provide you with hints when you get stuck.

Treat the interviewer as your teammate and turn the case interview into a business conversation.

Deloitte Group Case Interview

Deloitte is one of the few consulting firms that uses group case interviews in their final round of interviews. They conduct group case interviews because Deloitte’s work culture has a huge emphasis on teamwork and culture fit.

Here’s what to expect:

• You’ll be put into a group with 3 to 5 other candidates
• The interviewer will hand out case materials
• You’ll be given 10 minutes to review the case materials and prepare
• The group will have a discussion for 20 minutes
• During this discussion, interviewers will be observing candidates and will not interfere
• Afterwards, the interviewer will ask the group specific questions for another 20 minutes

Group case interviews can be challenging to prepare for because it is difficult to replicate the exact conditions to practice them. However, if you prepare for case interviews well, you will be in a great position to succeed in group case interviews.

Your goal in a group case interview is to add value to the group. There are six different ways that you can add value:

• Lead or facilitate the discussion : You can propose what topics to discuss, the order they should be discussed in, and how much time should be allocated towards each topic. If the group gets off track, you can bring the group’s focus back together.
• Expand upon other people’s ideas : If a group member suggests a great idea or raises a good point, build upon it and make it even better.
• Synthesize information : You can summarize information that other people have said and reconcile different viewpoints and ideas together.
• Keep track of time : You can volunteer to keep track of time and make sure that the group is on track.
• Play devil’s advocate : You can help your group develop strong ideas by testing the team’s thinking by considering potential risks or downsides of their ideas.
• Take notes: You can keep track of what other people are saying so that you can recall what has been discussed if any group members have questions.

Deloitte Group Case Interview Tips

Follow these five tips to shine during your Deloitte group case interview.

Tip #1: Treat your group members as teammates, not competition

The group case interview is not an exercise in which you are competing with others. Interviewers are trying to assess whether you would be a great teammate. Multiple people or even all people in your group can receive job offers.

Therefore, focus on adding value to the group rather than making yourself look better than your teammates.

Tip #2: Don’t speak too much, but don’t speak too little

If you speak too much, this may be seen as being too aggressive or controlling. If you speak too little, you may come off as shy or timid.

If you were to rank all of the members in your group by how much each person spoke, you would want to be roughly in the middle. This would be the perfect balance of speaking and listening.

Tip #3: Don’t interrupt or talk over your group members

Interrupting others when they are speaking is rude and disrespectful. You do not want to be inconsiderate or a jerk. Be nice and respectful to your group members.

Tip #4: Involve other people

If you observe that someone has not spoken much, ask them for their thoughts or opinions. If you notice that someone has been cut off when they were speaking, ask them to finish their thoughts after the person interrupting them has finished what they have to say.

These are easy ways to show interviewers that you are a considerate and helpful teammate.

Tip #5: Speak only if you are adding value to the group

Just because you are speaking a lot during the group case interview does not mean that you are doing well. Interviewers are not assessing you purely on the quantity of what you say. They care more about the quality.

Great teammates know when to speak and when to listen. Therefore, you should speak only if you are adding some kind of value to the group. Interviewers can tell when people are speaking for the sake of getting air time.

Deloitte Behavioral and Fit Interview Questions

In addition to case interviews, you will likely be asked a few behavioral or fit interview questions. There are ten questions that are most commonly asked.

1. Why Deloitte?

How to answer: Provide your three biggest reasons why you’re interested in working at Deloitte. You could mention that you loved the people that you have met from Deloitte so far. You can talk about Deloitte’s massive global presence, their expertise in nearly any industry or function, or their professional development opportunities.

2. Why consulting?

How to answer: Again, provide three reasons for why you’re interested in consulting. You could mention the fast career progression opportunities, the learning opportunities to develop soft and hard skills, or the level of impact that you can make right away in consulting.

3. Walk me through your resume.

How to answer: Provide a concise summary of your work experience, starting with the most recent. Focus on emphasizing your most impressive and unique accomplishments. At the end, tie your experiences to why you are interested in consulting and why you would be a great fit for Deloitte.

4. What accomplishment are you most proud of?

How to answer: Choose your most impressive, unique, or memorable accomplishment. Structure your answer by providing information on the situation, the task, the actions you took, and the results of your work. Explain why the accomplishment is so meaningful to you and what qualities that reveals about you as a person.

5. Tell me about something that is not on your resume.

How to answer: This is a great opportunity to highlight an accomplishment that is not related to your professional work experience. Perhaps there is a non-profit that you volunteer at, a side project or business that you work on, or a hobby that you have won awards or recognition for. Select an accomplishment that is impressive and interesting.

6. Tell me about a time when you had to lead a team.

How to answer: If possible, choose a time when you directly managed a person or a team. For this question and the following similar questions, make sure that you structure your answer. Provide information on the situation, the task, the actions you took, and the results of your work. This is known as the STAR method and is the most common way of answering behavioral or fit interview questions.

7. Describe a time when you faced conflict or disagreement.

How to answer: When answering this question, focus on emphasizing the steps you took to resolve the conflict or disagreement. Speak about the interpersonal skills you had to use in order to mediate the situation. Interviewers want to know that you can handle conflict in a constructive way.

8. Give an example of a time when you successfully persuaded someone.

How to answer: Choose a time when you were able to change someone’s mind who originally disagreed with you. Focus on emphasizing the steps that you took to persuade that person and what impact this had on the organization. Interviewers want to know that you are a great communicator and have strong people skills.

9. Tell me about a time when you failed.

How to answer: Choose a time when you failed to meet a deadline or did not meet expectations. You do not want to pick a failure that is too big or embarrassing. Focus on emphasizing what you learned from the experience and how you used that experience to deliver even better results in the next opportunity that you got. Interviewers want to see that you strive to learn from your past failures and are always working to get better.

10. Are there any questions that you have for me?

How to answer: This is a fantastic opportunity to get to know the interviewer on a more personal level. Ask them questions about their experience in consulting. Ask what their favorite case was or what they are looking to do next in their career. The more you can get the interviewer talking about themself, the more likely they will be to have a positive impression of you. People love talking about themselves, so make sure to listen attentively and ask follow-up questions.

The Deloitte Government & Public Services Interview Process

3 Tips For Passing The Deloitte Government & Public Services Interviews

Brief history of deloitte and what the company does.

Deloitte Touche Tohmatsu Limited, commonly referred to as Deloitte, is a multinational professional services network. The firm was founded by William Welch Deloitte in London, England in 1845 and expanded into the United States in 1890. Today, Deloitte continues to be headquartered in London but has offices that span over 150 countries and territories around the world.

Deloitte employs 345,000 professionals providing audit and assurance, tax and legal, consulting, financial advisory, and risk advisory services to nearly 90% of the Fortune Global 500 and thousands of private companies. Despite the continuously challenging global environment brought on by the pandemic, Deloitte’s 2021 revenues grew by 5.5% to reach $50.2 billion – making it the largest of the Big Four accounting and consulting firms by revenue.

Deloitte Government & Public Services (GPS) helps U.S. government leaders shape how they engage with their communities, nonprofits, and institutions. It was the company’s fastest-growing practice in 2021. (GPS works only with the U.S. government, but similar practices exist in other countries such as the Government & Infrastructure group in the U.K.)

Deloitte’s Government & Public Sector practice covers public sector clients in various American government agencies, including:

• Civil Government
• State, Local, and Higher Education
• Departments of Defense, Security and Justice
• Federal Health

The GPS practice focuses on technology-oriented solutions for government agencies and higher education clients, including cyber risk, cloud technologies, artificial intelligence, data science, and software engineering.    

On one hand, there are similarities between Deloitte’s Government & Public Service practice and its Commercial Consulting practice. Their market offerings are similar. Also, project resourcing for GPS and Commercial Consulting is from a shared pool of entry-level analysts and consultants in the Cross Consulting Group. Typically, Deloitte consultants align to a specific offering when they make senior consultant.

On the other hand, the GPS and Commercial Consulting practices also have some key differences. The GPS practice typically requires consultants staffed on the projects to be American citizens and to obtain a security clearance (which can be a long process). GPS engagements are also typically longer than the Commercial Consulting practice. They span anywhere between 6 months to a couple of years. However, given the length of the contracts, GPS practitioners often bill fewer hours and have less travel. This often leads to a better work-life balance for GPS consultants.

Similar to other management consulting firms and Deloitte’s Commercial Consulting practice, Deloitte’s GPS practice also looks for people who are able to demonstrate a mix of competencies such as problem-solving, creative thinking, and strong communication skills to help design and implement solutions for their clients. As Deloitte’s GPS practice also focuses on technology-oriented solutions, they also look for people with technical skills to provide a variety of expertise to their clients, which includes:

Artificial Intelligence – applies AI and machine learning techniques to accelerate and improve decision-making.    

They look for people who are:

• familiar with a variety of analytics and data tools,
• at ease with new technologies, algorithms, and technology concepts,
• experienced with AI solutions and technologies, and
• conversant in AI languages and programming.

Cloud  –  builds cloud solutions that transform data into actionable intelligence.

Deloitte looks for people who:

• enjoy troubleshooting tough problems and finding ways to simplify processes through the cloud,
• thrive in a highly collaborative, diverse team environment,
• want to build innovative solutions with experimentation and learning, and
• know how to leverage cloud capacities for government agencies and public institutions.

Cyber – combats the growing challenges of cyber threats.

Here, they look for people:

• with an interest in designing solutions that address technology risk challenges,
• who want to put their technology experience to work combatting critical security threats, and
• who have practical project or work experience in the areas of IT infrastructure, systems architecture, and security safeguards.

Data Science –  gather and analyze large sets of structured and unstructured data to help clients make smart decisions by applying statistics, AI, analytics, machine learning, and other tools and techniques.     

People who thrive have:

• strong critical thinking skills and passion for exploring deep into data,
• practical project or work experience managing data sets and providing insights derived from the data, and
• interest in expanding their repertoire and know-how of AI and machine learning models, COTS tools, programming and query languages, and visualization technologies.

S alesforce – implements the Salesforce platform.

They are looking for people who can:

• help tackle hard problems with smart engineering and creativity,
• creatively use technology to help enhance digital customer and employee experiences, and
• help their clients use Salesforce in innovative ways.

Software Engineering – designs, develops, and implements large-scale software applications and integrated systems including application architecture design and optimization, application modernization, business process management, and solution integration, custom application design and development, and large-scale technology delivery program efforts.

Deloitte looks for people who  are:

• energized by solving business challenges through the design and development of tech solutions and have a solid understanding of the software development lifecycle,
• passionate problem-solvers with an innate curiosity about technology, and
• experienced in coding and application design and development and can speak the language of both technology and business.

The Deloitte Federal Government and Government & Public Services Interview Process

Deloitte typically has a recruiter round of interviews followed by two consultant rounds. Broadly, each interview runs for an hour and has a behavioral section and a case interview. The breakdown of each round is:

Screening Round – Recruiter interview

Some candidates have a phone interview with the recruiter before proceeding to the next round. This round often covers some behavioral questions or technical questions for the recruiter to gauge the candidate’s fit for the role.

Round #1 – Behavioral Interview

The first round of interviews is often a phone interview with a senior consultant or principal and primarily covers behavioral / culture fit questions.

Round #2 – Technical / Case Study Interview

Second round interviews are often with principals or partners. They cover behavioral questions, cases, and a technical interview. Case study questions usually reflect the role you are applying for. For example, if you are applying for a GPS Strategy and Analytics position, you may expect the case to be about strategy and analytics for a government agency. Alternatively, if you’re applying for human capital analyst role, you may receive a question about implementing solutions based on employee feedback but will not have quantitative questions.

Key note! The interview processes differ by role and office location. Some offices have behavioral and case study interviews in both rounds 1 and 2. In addition, a technical role will include more technical interview rounds while the consulting roles will be more focused on case study interviews. Ask your recruiter for more details about your interviews.

See our articles on Recruiter Interviews , Case Interviews , and Behavioral Interviews for more information on how to prepare for these different types of interviews.

Deloitte’s GPS case interviews are often the second part that follows the behavioral section. The interviewer usually leaves about 30 minutes for this section. Similar to case interviews at BCG and Bain, Deloitte GPS case interviews are interviewee-led , where the interviewee is expected to walk the interviewer through their thought process in getting to a recommendation.

If you’re new to case interviews, our Guide to Case Interviews Prep will help you understand what case interviews are and the 4-step approach to answering them. These 4 steps include:

• The opening – This is an important step to make sure you understand and are clear on the client’s problem.
• The structure – This is where you think through the factors relevant to the problem and organize them so that you address them in a logical manner. You may use an issue tree to organize the factors at this stage.
• The analysis – This is where you gather relevant data to identify the factors most relevant to the client’s problem and develop recommendations.
• The conclusion – In this step, you present your recommendation to the “client” (the interviewer) in a well-structured and persuasive manner.

In addition to our guide, Deloitte also offers a Case Interview Prep tool where you can find case examples that match the role you’re applying for and your educational background (for example, undergraduate or advanced degree backgrounds). With Deloitte’s interview prep tool, applicants can also compare their answers with Deloitte’s sample answers to identify areas for improvement.

Some sample case questions include:

• How would you implement an application across a government agency (for example, Enterprise Resource Management tools) and how would it likely impact the agency’s employees?
• Propose a new architectural plan and discuss how you’d go about analyzing the current systems and interviewing stakeholders.
• Develop an application to transmit personalized safety messages to drivers to encourage safe driving in order to reduce accidents, lower fuel costs, and optimize delivery schedules.

What Do the Deloitte Behavioral Interviews Look Like?

Deloitte asks behavioral questions throughout the interview process – from recruiter interviews through second round interviews with principals and partners. Deloitte interviewers often allocate 20 to 30 minutes in their rounds for the behavioral interview.

The behavioral interview is designed to assess if the candidate is the right “fit” for the company and its culture, as most of its work will require the candidates to work cohesively as part of the team. The behavioral interview is an opportunity for the candidate to demonstrate their “softer” skillsets and provides an opportunity for them to understand more about Deloitte and its values and culture.               

Pro Tip! Answer the behavioral interview by sharing compelling stories! Tell stories from your personal experience and the impact you drove. We suggest you use the A STAR(E) structure to help you tell a more compelling story.

A STAR(E) stands for:

A – Answer – Start with a 1-sentence answer to the interviewer’s question.

S – Situation – Describe the situation. When and where did the events in the story happen? Who was involved?

T – Tension – What was the conflict?

A – Action – What actions did you take to resolve the tension?

R – Result – What were the results of your action?

(E) – Effect – What did you learn from the situation and the events that followed it? However, this is optional as it may not be essential in every story.

Deloitte Government & Public Service asks more leadership-related questions during their behavioral interviews, so be sure to have some answers prepared. Common questions include:

• Tell me about a time when you found it difficult to work with someone.
• Tell me about a time you faced a difficult employee.
• Have you led a team? Tell me about that experience.
• Describe a time when you had to use ethics to handle a difficult situation in the workplace.
• What is your leadership style?

1. Practice Cases with a Case Partner

Leverage the tips and the tools provided in this post to improve your ability to work through case studies. Casing does not come naturally to most people, so practice answering different case study examples with a case prep partner so you can improve.

2. Be Structured and Consistent

Deloitte requires candidates to go through 3 rounds of interviews, which can be stressful. Developing a consistent approach to answering the behavioral interview and case interviews (for example, the A STAR(E) structure and the 4-step case interview approach), will help keep your answers concise and impactful.

3. Be Intellectually Curious

Demonstrate your interest in Deloitte Government & Public Sector’s work and the impact you want to deliver through your answers and questions throughout the interview. Ask questions that will help you get to the second- or third-order insights and “so-what” to show the interviewer that you are interested to know more and learn more about the industry or client.

Top 25 Deloitte Interview Questions (With Sample Answers)

Mike Simpson 0 Comments

By Mike Simpson

Deloitte is part of the Big Four , boasting more than 330,000 employees worldwide. With that high of a head count, you might think that getting a job at Deloitte isn’t overly difficult. However, the company receives more than 500,000 applicants annually, so you really need to nail those Deloitte interview questions if you want to secure an offer.

Luckily, with the right strategy, impressing is much easier. Here’s a look at what you need to do.

How to Answer Deloitte Interview Questions

Alright, before we hop into the interview questions themselves, let’s take a moment to talk about how to answer Deloitte interview questions. The hiring landscape at Deloitte is incredibly competitive, mainly because the company has a stellar reputation in its industry. As a result, you need a winning strategy if you’re going to stand out.

First, it’s important to understand that most – if not all – jobs at Deloitte will have a multi-round hiring process. Primarily, this is because the company has to sift through a stunning number of applicants, particularly for accounting positions.

Since that’s the case, you can expect some tough questions that will test your knowledge about the industry. Plus, you’ll see plenty focused on your experience and skills, coupled with questions that help the hiring manager gauge your personality.

Alright, but how do you answer the questions? Well, that depends on the type of question asked, which we’ll cover shortly. What you need to worry about first is gathering information, and that means research.

Start by reviewing the job description. Look at the skills and experience Deloitte wants to find, as well as for words that give you insights about traits. Terms like “dedicate” and “focused” are clues about the type of person the hiring manager wants to find, so make a note of them if you see them.

Next, take a trip to the company’s website and read its mission and values statements. Look at the career page and Deloitte’s social media profiles for insights into the culture. Finally, read reviews written by employees on career sites. By doing so, you can get a solid idea of what Deloitte wants.

Now, you can use that information to prepare answers for your interview. Traditional Deloitte interview questions focus on your knowledge and skills, often feeling a bit like a pop quiz you’d tackle in college.

With behavioral and situational questions, the vibe is different. Here, you need to tell compelling stories that outline your past experience or cover how you’d handle hypothetical situations. For those, a mix of the STAR Method and the Tailoring Method will typically do the trick.

Top 3 Deloitte Interview Questions

Saying that Deloitte is massive feels like an understatement. The company is a giant in the accounting industry, providing a range of services in areas like risk assessment, auditing, and financial advising.

However, like most firms of this size, the company hires professionals in several niches. For example, along with its accounting-related teams, it needs everything from tech professionals to cleaning crews.

When you come into a Deloitte job interview, the questions you’ll get asked focus on your field. Since that’s the case, not all candidates face the same ones.

However, as one of the Big Four accounting firms, we’re going to focus on financial questions. With that in mind, here are the top three Deloitte interview questions.

1. Why did you choose accounting as your field?

As a Big Four account firm, the hiring manager will likely ask about what drew you to the field. It’s a way for them to gauge your passion, ensuring that accounting has some kind of special meaning to you and that you’re intrinsically motivated. In your answer, highlight something that made accounting feel like the perfect fit.

SAMPLE ANSWER:

“When I was in grade school, math was easily my favorite subject. I loved the concrete nature of it. As long as you followed the correct process, you can find the right answer, and that was very fulfilling to me. As I got older, I also saw the value in accounting. Whether it was my parents reviewing a budget, me planning to cover the cost of college, or my first steps into the working world, calculations were the path to answers. Since many people struggled with handling those calculations – effectively making it harder for them to critical answers – I realized that my passion could become their solution. I entered college majoring in accounting with the goal of benefitting people and businesses, allowing me to use my hard-earned skills for the betterment of others.”

2. How do you handle multiple, potentially conflicting deadlines?

Deloitte is a fast-paced workplace, and missed deadlines can wreak havoc. This is particularly true if you work with highly regulated clients with strict reporting requirements, as being late is incredibly costly to them.

Here, you want to outline the steps you take to ensure you can handle a challenging workload, particularly when deadlines that apply to multiple clients are approaching. Ideally, you want to outline a clear, proven strategy.

“When I have multiple high-priority assignments with similar deadlines, I embrace organization and schedule. I’ve learned that my calendar is my ally. In it, I can block out time for various tasks and set up notifications that let me know when to transition. By doing so, not a moment is wasted, and I remain focused. Plus, I don’t get lost in one project, as my notifications serve as critical reminders. Finally, it alerts others with calendar viewing privileges about my availability, limiting interruptions. As a result, I’ve found my approach is highly effective at keeping me on target, even when dealing with multiple, potentially conflicting deadlines.”

3. What steps do you take to ensure the accuracy of your work?

If one thing is true about accounting, it’s that accuracy isn’t just important; it’s critical. Since that’s the case, there’s a good chance you’ll be asked a question like this one.

The hiring manager wants to know that you have a strategy for checking your work and ensuring accuracy. Outline any processes you use to make sure your entries, data, and calculations are correct.

“When it comes to ensuring accuracy, I use a two-fold approach. First, I believe adamantly in checking my work as I go. It only takes a moment to double-check an entry or calculation, so I make sure to do that every few entries or lines as confirmation. Second, I take advantage of any built-in tools designed to check or confirm entries, calculations, or data. Many software programs have features that can perform those tasks, so I make sure to learn how to use them to my advantage. Generally, I’ve found this process is highly effective. However, if I ever have any doubts, I’ll go the extra mile and request a review from a colleague, and I offer to do the same for them. Sometimes, a second set of eyes is the key, and by doing it in kind, everyone excels.”

22 More Deloitte Interview Questions

Here are 22 more Deloitte interview questions you might be asked:

• Why do you want to work for Deloitte?
• Why would you choose Deloitte over a competitor?
• Tell me about a time when you used persuasion to change an outcome.
• How do you remain focused while handling audits?
• What’s something unique that you can bring to Deloitte?
• How does Deloitte stand out from the other companies in the Big Four?
• What’s the difference between private equity and hedge funds?
• Tell me about a time you had a conflict with a team member.
• If you felt overwhelmed by your workload, what would you do?
• Which languages are you fluent in?
• What accounting function do you enjoy most? Which do you enjoy least?
• Which of your traits helps you thrive in the accounting field?
• Can you give me an example of a time when you built a positive client relationship?
• If a client is unhappy, how do you remedy the issue?
• How do you approach a client if you won’t be able to meet a deadline?
• What compliance-related accounting requirements are you familiar with?
• Tell me about a time when you acted ethically even though it was hard.
• If you found out that a coworker complied with an unethical request from a client, what would you do?
• What’s the most valuable thing you learned in college? What about in your previous roles?
• How do you calculate free cash flow?
• If you need to deliver bad news to a client, how do you go about it?
• What accounting platforms are you familiar with?

5 Good Questions to Ask at the End of a Deloitte Interview

When your interview is coming to a close, a magical moment happens; you’ll get a chance to flip the script and ask the hiring manager a few of your own questions. This is a major opportunity, and you don’t want to let it pass you by.

Why? Because it’s a chance to find out more about the company, its culture, and the job. Plus, it helps you seem engaged and enthusiastic, both of which can make you a more attractive candidate.

As you proceed through the interview, make a mental note if any questions come to mind. That way, you can bring them up when you’re given a chance to ask questions. However, you also want to make sure you have a few questions in your back pocket. Then, if nothing comes up during the interview, you’ll have a few things to ask.

If you don’t know where to begin, here are five good questions to ask at the end of a Deloitte interview:

• What attracted you to Deloitte, and has the company met that expectation?
• How is success measured in this position?
• How does Deloitte help its accounting teams remain current on regulatory changes or relevant laws?
• Along with accounting expertise, what skills or traits do you feel a candidate needs to thrive in this role?
• How has this position changed over the past five years, and how do you envision it evolving over the next five years?

Putting It All Together

At this point, you should have a pretty good idea about how to tackle a Deloitte job interview. Use every tip above to your advantage, and practice those Deloitte interview questions so that your response flow naturally. That way, you can showcase yourself as the exceptional candidate that you are, increasing your odds of landing an offer.

Here are some essential differences between triggers and SQL-stored procedures:

• When you make a trigger, you must choose an event and an action that will happen when the trigger is run. Stored procedures are just SQL statements that don't need an event or action. Stored procedures can be called directly from an application, SQL commands, or stored procedures.
• When the event happens, the trigger runs on its own. A stored procedure can be run by hand or by an application that calls it.
• You can call a stored procedure from inside a trigger, but you can't call a trigger from inside a stored procedure.
• A trigger runs automatically, while a stored procedure runs when another block makes a procedure call.
• The front end can invoke a stored procedure but not a trigger.
• An input parameter can be given to a stored procedure but can't be given to a trigger.

2. What is backpropagation?

Backpropagation is a common way for an artificial neural network to figure out the gradient of the loss function for the weights. It is often used as part of algorithms that change the consequences to improve the performance of a network.

3. What is the difference between a crossover and a straight-through?

Straight through:

• Between a modem and a computer, switch, or router
• Connecting a computer to a switch
• Connecting a router to a hub
• CAT6/CAT5 peripheral extenders

Cross over:

• Between two networking devices
• Between two PCs
• The connection between hubs
• The connection between switches
• Connecting a router to a computer

4. What is SMTP?

SMTP (Simple Mail Transfer Protocol) deals with internet mail and offers important mail delivery services on the IP/TCP protocol stack. Most email solutions which send emails on the internet use SMTP to send messages from one server to another. The messages can be retrieved with an email client through IMAP or POP.

5. What is clustering support?

As the first step in machine learning, we often group examples to learn about a subject (a data set). Clustering is the process of grouping examples without labels.

6. What is the role of IEEE in computer networking?

The IEEE standards for computer networks ensure that different devices can talk to each other and work well together. They also ensure that the network service, such as the Internet and related technologies, follows a set of rules and best practices so that all the networking devices can talk to each other and work well together.

Since different kinds of companies make computer systems, the IEEE's computer society started Project 802 in 1985 to make it easier for different devices to talk to each other.

Common Deloitte Interview Questions

We've compiled a list of the seven most frequent Deloitte interview questions, sample responses and precise advice on how to put your best foot forward and showcase your most desirable talents and abilities to help you move one step closer to landing your ideal job at Deloitte. Reviewing some of the most popular interview questions asked by Deloitte hiring managers can help you prepare and enter the interview with a clear head and a well-thought-out plan of what to say. Setting yourself up for success and getting ready for your job interview may be as simple as conducting a practice interview with these commonly asked questions before the big day.

The following are the seven most commonly asked Deloitte interview questions and answers:

1. What made you apply for a position at Deloitte?

Hiring managers across every organization ask this question to measure your interest and learn more about the organization you're applying to. Deloitte is no exception.

How to Answer: Prepare for this question by researching Deloitte ahead of time and becoming familiar with its culture, mission, as well as professional principles. Try to highlight your expertise and at least one factor that drew you to the company in your response.

Example Answer: As an experienced financial analyst, I'm dedicated to providing the best possible service to my clients and the knowledge they need to make informed financial decisions. I've been looking for a way to make a bigger difference in my community, and this position appealed to me because your company is known for its apparent market success, rapid expansion, and inclusive work atmosphere.

2. What do you know about Deloitte?

This question, or something similar, will very certainly be asked throughout the interview process at Deloitte, regardless of the position you're looking for.

How to Answer: Prepare for your interview by researching and having a few significant and relevant facts about Deloitte on hand. As a general rule, know everything there is to know about the company, including what they specialize in, where they are headquartered, and when they were created.

Example Answer: Throughout my undergraduate education, I constantly followed Deloitte's work and was intrigued by the firm's recent development, particularly the acquisition of Terbium Labs. Since its founding in London in 1845, Deloitte has developed tremendously. One of the Big Four, Deloitte is regarded as one of the largest privately held professional services firms.

I am confident in my ability to assist Deloitte in continuing to expand and better the lives of millions of people around the world.

3. How did you get into the field of accounting?

If you're interviewing with Deloitte, you're probably in the accounting sector. This is a common question asked by Deloitte hiring managers to determine your professional interests.

How to Answer: This popular Deloitte interview question can be answered by recalling the specific aspects of accounting that drew you to the area and highlighting your devotion to the job.

Example Answer: Accounting gives me enormous pleasure. I enjoy my job because it both challenges and fulfills me while also allowing me to serve individuals from all walks of life. My early interest in financial data analysis and calculating metrics drove me to the field.

4. Tell me about a point in your career where you used negotiation skills to change the outcome of something.

During Deloitte job interviews, this is one of the most often asked questions. If you want to work for Deloitte, you'll require exceptional negotiation and communication abilities, regardless of department or function.

How to Answer: Try to recall a time when you utilized your negotiating abilities to close a sale, explain a complex concept to a client, or influence the outcome of a team meeting. You should attempt to demonstrate excellent communication and interpersonal skills in your response.

Example Answer: At Ernst & Young, I used my negotiating talents to persuade a customer not to seek financial assistance from a competitive firm. After listening to the customers' concerns, I addressed them directly. I met with their Chief Financial Officer extensively, resulting in negotiating a new consulting agreement that was more suited to the company's needs. In my experience, clear and powerful communication is crucial in each negotiation.

5. How do you manage multiple deadlines and tasks?

Working quickly and achieving deadlines are critical to employee success at Deloitte. Passionate, focused, and efficient employees are significantly more appealing to hiring managers.

How to Answer: You should emphasize your time management and organization skills in this response.

Example Answer: With more than three years of professional auditing experience, I've honed my time management skills and can easily stay on target while managing many assignments and deadlines on any given day. To meet deadlines and accomplish all activities promptly, I prioritize and plan tasks, set goals, delegate when appropriate, and keep clear communication with my team.

6. How do you stay focused when performing audits and other tax and legal services? 

Working with numbers might become tedious at times, but remaining focused is crucial if you want to work with Deloitte. Hiring managers frequently ask this question to assess your ability to complete tasks and remain focused on the job.

How to Answer: When providing audits and legal services, expressing your capacity to be methodical and paying close attention to detail is a wonderful approach to responding.

Example Answer: Auditing and reviewing figures are two things I enjoy doing. I am hyper-aware of the task at hand at all times, paying close attention to detail and scrutinizing data for any fraud, infractions, or abnormalities. I tackle all audits and financial assessments analytically and rigorously to keep focused.

7. What can you bring to Deloitte?

During job interviews, Deloitte recruiting managers frequently ask this question to further analyze potential workers' talents and competencies.

How to Answer: This is an excellent opportunity to showcase your finest abilities. Answer this question by mentioning any relevant work experience you have and emphasizing your best professional qualities.

Example Answer: I am convinced that with over five years of auditing and tax experience, I can help Deloitte expand and broaden its client base while continuing to provide the high-quality financial services that Deloitte customers expect. 

When auditing limited companies, huge organizations, and small firms, I have a keen eye for detail, a vested interest in the financial system, and a demonstrated track record of providing remarkable outcomes.

Deloitte Technical Interview Questions

1. what do you mean by tunnel mode.

Tunnel Mode Tunnel Mode is a way to send encrypted data over the Internet. Both the data and the original IP address are encrypted. The Encapsulating Security Payload (ESP) works in both Tunnel Mode and Transport Mode.

2. What is C programming language?

C is a popular, easy-to-use, and flexible programming language that can be used for many different things. It is a structured, machine-independent programming language used extensively to write applications, operating systems like Windows, and other complex programmes like the Oracle database, Git, Python interpreter, and more.

People say that "C" is the programming language of gods. C is the foundation of programming. If you know "C," it's easy to learn other programming languages that use the same ideas as "C."

3. What is the difference between C and Java?

C is an Object-Oriented Programming Language, while Java is a Procedural Programming Language. Java is a high-level language, and C is a middle-level language.

4. What is polymorphism in programming?

In programming languages and type theory, polymorphism is when things of different types share a single interface, or a single symbol can stand for more than one type.

Object-oriented programming can't work without polymorphism (OOP). Classes describe what an object is. They have the potential to get new properties and methods. We could, for example, make an object with the class Car. This car might have been:

• Things like colour, make, model, and speed at the moment
• Methods are functions that the class calls, like "go," "park," "stop," "turn right," "turn left," and so on.

5. How can you create and use threads in Java?

One way to describe thread is as a light process. Thread uses fewer resources to create itself and stay alive because it shares the process's resources. Java's main thread is the one that starts when the programme does. Because of the main thread, the slave thread is made. This is the last thread that needs to finish running.

6. What is the difference between char and varchar in DBMS?

Even though both char and varchar are character data fields, char is a data field with a fixed length, and varchar is a data field with a variable size.

• Char can only store non-Unicode strings of a fixed size, but varchar can store strings of different sizes.
• For data that changes a lot, Char is better than varchar. This is because a row of data with a fixed length doesn't tend to break up.
• Char will only take up the fixed amount of space set when the variable is declared. But varchar will take up as much space as the data it contains, plus 1 or 2 bytes for the length prefix.
• If the data is less than 255 characters, only one byte is set aside, but if it is more than 255 characters, two bytes are set aside. If we use a char to store a 'Y' or 'N' flag, it will take one byte, but if we use varchar, it will take two bytes, plus an extra byte for the length prefix, to store the flag.

7. What is an implicit cursor?

The implicit cursor is a cursor that the Oracle server has made and is in charge of. The implicit cursor is always used to process the selected statements internally. The implicit internal cursor runs in the background when you run a select statement.

8. What is a proxy server?

A proxy server is a computer system or router lets users connect to the internet. So, it makes it harder for hackers to get into a private network. It is a server called an "intermediary" because it sits between end users and the websites they visit online.

A computer uses an IP address to connect to the internet. This is like the street address of your home. It tells incoming data where to go and gives outgoing data a return address so other devices can verify it. A proxy server is a computer connected to the internet and has its IP address.

9. What do you know about machine learning?

Machine learning is a branch of artificial intelligence (AI) and computer science that tries to mimic how humans learn using data and algorithms. Over time, it gets better and better at doing this.

Machine learning is an integral part of data science, which is constantly growing. Statistical methods teach algorithms to classify or make predictions and find critical insights in data mining projects. From then, applications and organisations may use these data to inform decisions that should have a positive impact on key growth indicators. As big data keeps growing and getting bigger, the market will need more data scientists. They will have to help figure out the most important business questions and what data is required to answer them.

Your AI/ML Career is Just Around The Corner!

10. Can you explain function overloading?

Object-oriented programming lets two or more functions with the same name, but different parameters work together. This is called function overloading. Function Overloading is when a function name is used for too many other tasks. In Function Overloading, the "Function" name should be the same, but the arguments should differ.

11. What do you know about the Python language?

Python is a high-level programming language that is interpreted, object-oriented, and has dynamic semantics. Its high-level data structures and dynamic typing and binding make it a good choice for Rapid Application Development and for use as a scripting or glue language to connect existing components. Python's syntax is simple and easy to learn. It emphasises being easy to read, which lowers the cost of maintaining programmes. Python supports modules and packages, which makes it easier to break up programmes into smaller parts and reuse code. Free source and binary distributions of the Python interpreter and the entire standard library are available for all popular platforms. They can also be shared freely.

12. What do you understand about tunnelling protocol in Computer Networks?

Tunnelling is a way to connect networks of the same type from the source to the destination through a network of a different kind.

In this case, the packet from one network gets to the other through a different type of network that links the two.

13. What are the pros and cons of star topology in Computer Networks?

Advantages of Star Topology is:

• Adding more computers to a star topology network doesn't cause any problems.
• In a star topology, it's easy to find and fix broken parts.
• In a star topology, if a cable breaks, it will only affect one workstation.
• Star topology is more accessible than bus topology or ring topology.
• In a star topology, if one node has a problem, it won't affect the other nodes.
• It can grow and change more than a peer-to-peer or ring network.
• In star topology, adding or removing nodes from the central hub is easy without affecting the other nodes.
• It's easy to set up and keep up.

Cons of Star Topology: 

• More cables are needed to connect networks.
• In a star topology, the cost of concentrators or hubs is very high.
• There aren't many routes in the star topology.
• If the hub breaks, the whole network falls apart.
• The star topology cost is higher than other topologies because it needs more network.

14. Discuss the physical layer of the OSI (Open Systems Interconnection) Model in the context of Computer Networks.

The Open System Interconnection (OSI) Model, a physical and electrical representation of the system, start with the Physical Layer. It is made up of different network parts like power plugs, connectors, receivers, different types of cables, and so on. The Physical Layer moves bits of information from one device (like a computer) to another (s).

15. Differentiate between hierarchical database models and networks in DBMS.

Hierarchical Data Model:

This type of data model has been around for the longest. In 1968, IBM came up with it. It puts data into a structure that looks like a tree. The following are parts of the hierarchical model:

• It has nodes and branches that connect them.
• The root node is the node at the very top.
• If there is more than one node at the top level, they are called root segments.
• There is only one parent for each node. 
• A parent can have many children.

The Network Data Model is the next step from the Hierarchical Data Model. Instead of a tree structure, it uses directed graphs to organise data. A child can have more than one parent in this situation. It uses the idea of Records and Sets, two data structures.

16. Explain the DDL (Data Definition Language), DML (Data Manipulation Language) and DCL (Data Control Language) statements in SQL.

• Code the data structures using the Data Definition Language (DDL).
• Data Manipulation Language (DML): Use these structures to store and play with data.
• Data Control Language (DCL): Choose who can change the structure and the data.

17. What is a Kernel in OS?

Kernel is the central part of an operating system that controls how the computer and its hardware work. It contains how memory and CPU time is used. It is an essential part of an operating system. The kernel acts as a link between programmes and the data processing that happens at the hardware level. This is done through inter-process communication and system calls.

Kernel is the first part of an operating system to load into memory. It stays there until the operating system is shut down. It is in charge of managing discs, tasks, and memory.

It decides which process should be given to the processor and which should stay in the main memory. It acts as a bridge between the user's programmes and the hardware. Kernel's main job is to manage how software (like user-level apps) and hardware (like the CPU and disc memory) talk to each other.

18. What are the advantages and disadvantages of using threads in context to the OS?

Threads have these benefits:

• Running input, calculations, and output as three separate threads may improve the performance of an app that does all three. One of the other threads can do calculations while the input or output thread waits for a connection. A multithreaded programme is also a good choice for a server app that handles multiple network connections.
• Now that most desktop and laptop computers have CPUs with multiple cores, using multiple threads within a process can help a single process make better use of the hardware resources available if the application is correct.

In general, switching between threads is much less work for the operating system than switching between processes. So, multiple threads use fewer resources than various processes, and it is easier to run programmes that logically need to run on many threads on systems with only one processor. Still, it's important to remember that writing a multithreaded programme is problematic because it takes time to design.

Bad things about Threads:

• Designing programmes with multiple threads take a lot of care. In a multithreaded programme, it is easy for minor timing errors or errors caused by the unintentional sharing of variables to happen. Alan Cox, a well-known Linux expert, has said that threads are also known as "how to shoot yourself in both feet at the same time."
• Debugging a programme with multiple threads is a lot harder than debugging a programme with only one thread because it's hard to track how the threads interact.

19. How does reference counting deal with objects that are memory allocated in context to OS? When doesn't it get things back?

Reference counting is also one of the simplest ways to eliminate garbage. It also lets you take care of resources that aren't in memory, like operating system objects, which are often much more challenging to find than memory.

Why is it that a single serial port is controlled by a single interrupt-driven I/O (input/ output), but a front-end processor, such as a terminal concentrator, is managed by a polling I/O? Answer this question in light of OS.

Polling can be faster than I/O, which is driven by interrupts. When the I/O is short and happens often, this is the case. Even though a single serial port doesn't do I/O very often and should therefore use interrupts, a group of serial ports, like those in a terminal concentrator, can do a lot of short I/O operations, and interrupting for each one would put a lot of stress on the system. The load could be reduced with a well-timed polling loop that does not waste resources by repeatedly iterating when no I/O is required.

19. Explain transaction atomicity in context to OS

What makes a transaction atomic is determined by its context or the environment in which it is being used. For example, in an online airline booking system, a booking may be made up of two separate actions that make a transaction: paying for the seat and reserving the seat for the customer who just paid. Business logic says that these two actions, even though they are different, must happen at the same time. Having one without the other can cause problems. For example, the system might let two different people reserve the same seat.

20. What is the difference between a declaration and a definition for a variable or a function in C?

When you declare a variable, you tell the compiler its name, what kind of value it holds, and, if it has one, its initial value. In other words, the declaration gives information about how a variable works. Whereas "Definition of a variable" says where the variable is stored. In other words, when the variable is defined, space is set aside for it. In the C programming language, defining and declaring a variable happens at the same time. In other words, there's no difference between saying something and defining it.

21. What are the different storage classes in C?

Auto: This is the default storage class for all variables declared inside a function or block. So, the word "auto" is rarely used when writing C language programmes. Auto variables can only be used inside the block or function where they have been declared (which defines their scope).

Extern: Extern storage class tells us that the variable is defined somewhere else and not in the same block where it is used. The value is given to it in a different block, and that block can also change or overwrite it.

Static: This storage class is used to declare static variables, often used when writing C language programmes. Static variables keep their value even after they are no longer in use.

Register: This storage class sets up variables called register that work the same way as auto variables. The only difference is that if a free registration is available, the compiler tries to store these variables in the microprocessor's register.

22. What is generational garbage collection in the context of Java? What makes it so popular?

Java's automatic memory management is done through "garbage collection." Java programmes are turned into bytecode, which can be run on a Java Virtual Machine (JVM). When Java programmes run on the JVM, objects are made on the heap, a section of memory set aside for the programme. Some things will become useless in the long run. The garbage collector looks for these objects that aren't being used and delete them to make room in memory.

23. What are access specifiers in C++?

Access modifiers, another name for access specifiers, are used to implement essential parts of object-oriented programming called "Data Hiding."

They are used in a class to set how class members can be accessed. But it limits the class members, so they can't be directly accessed outside the class.

Interview Process at Deloitte

It takes professionalism, precision, and tremendous competence to get a job at Deloitte. Knowing what to expect and thoroughly preparing for your job interview will help you come across as a knowledgeable, composed, and capable candidate and prepare you how to give your best in an interview with globally reputed organizations. 

The following is a general outline of what to expect at your Deloitte job interview:

Submit an Application

The most critical aspect of the hiring process is submitting a polished job application. The fastest way to get an interview and eventually be employed by Deloitte is to submit a detailed, edited, and well-constructed job application. Even though job applications can be filed online, many Deloitte workers first apply via college career fairs or through employee referrals.

Having a personal link within the organization, whether through a professional connection or a connection with a hiring manager, will greatly increase your chances of being called in for an interview.

First Interview

You will be contacted for an interview if the hiring managers at Deloitte are impressed with your application. Within one to three months, you should receive an email or phone call from them. The initial round of interviews may be held in person, over the phone, or over Skype or video conference, depending on the position you're looking for and the location of the employment. The initial interview for a position at Deloitte is usually conducted by a human resources professional and comprises basic interview questions, such as critical thinking and resume-based questions, regardless of the role.

A short JAM, or Just A Minute round, is sometimes included in Deloitte's first round of interviews, where a job applicant is assigned subjects to speak on for one minute.

Second Interview

If you aced your first Deloitte interview, your work isn't done yet. Deloitte requires most new workers to go through two to three rounds of interviews before getting hired. If your first interview was conducted in person, the second interview can be completed shortly after the first. Deloitte is recognized for conducting in-depth interviews with job seekers, frequently asking applicants to go to one of their over 700 global offices for a full day of interviews.

Deloitte's second job interview usually lasts about 30 minutes and includes behavioral and situational interview questions. In case you're seeking a job for a highly specialized or technical position, such as an engineer or programmer, the interview is frequently conducted by a senior manager and contains a slew of situational interview questions.

Third Interview

Finally, if you're seeking a senior or highly technical position inside the company, you'll very certainly be forced to go through another round of questioning with senior management, partner, department director, or possibly a panel of interviewers after the second interview.

Only the most eligible individuals are invited to the third interview. During the third interview, it's very important to put your best foot forward because every word will be scrutinized and evaluated. The third interview, like the second, usually includes additional situational and job-specific interview questions.

Pre-Employment Aptitude Testing

You may be requested to do an aptitude test to further analyze your skills to perform the work, depending on the exact post you're applying for, your skill level, and your professional experience. A quantitative, logical, and verbal reasoning section is usually included in the Deloitte pre-employment aptitude test to assess your talents.

The test may be more involved for specific professions, such as audit associate or computer programmer, requiring applicants to complete a mock audit, answer more math questions, or build a java algorithm .

Orientation and Training

Only orientation and training remain in the onboarding process once you've received a formal employment offer. You'll probably be required to fill out paperwork, consent to a background check and fingerprints, and take an employee drug test during this stage.

Every Deloitte employee, regardless of rank, is expected to attend new employee orientation, which includes a thorough review of corporate policies and procedures. Following orientation, you'll start your new job, with the first few months usually being spent in training or probation. Depending on the role or your degree of competence, you may be required to undergo significant one-on-one training or hardly any at all.

Frequently Asked Questions

1. are deloitte interviews hard.

It makes no difference if the Deloitte interview is difficult or simple. The truth is that the more you prepare for the interview, the more likely you are to succeed. Study rounds, questions, stages, etc. Understand the role completely, including what they expect from you, the skill sets you'll require, and the credentials you'll need.

2. Where do you see yourself in 5 years?

Tell them you want to learn and master a particular technology. You must persuade them that you intend to stay with the company for a longer period. You can say you want to improve your skills, gain more confidence, and keep your job in their company, and within the next five years, you want to be acknowledged as an authority in that field. You can become a seasoned specialist if given the opportunity. The recruiter is just interested in finding out how long you plan to stay with the company and how satisfied you are with your current position.

3. What is your salary expectation?

This is a challenging one. You can choose to quote the exact amount or not, but you must advise them of the percentage increase you are considering. Instead of requesting a certain wage, demonstrate your commitment to the position.

4. What is the starting salary for a fresher in Deloitte?

Deloitte's starting salary for freshers is roughly 4.5 lakhs per year.

5. Why should we hire you?

The interviewer is working to identify whether you would be a good fit for their organization. As a result, you will need to persuade them. You can say something like, "I can grab information quickly". You can discuss your abilities, skills, and past experiences in this section, as well as how you can bring something fresh to the role.

6. What are your strengths and weaknesses?

You can address your strengths by elaborating on the following points:

• Goal-oriented and versatile
• Ability to handle pressure
• Strong communication skills

The following are the weaknesses which you can address:

• Self-critical
• Multi-tasker

7. How do you handle stress or tight deadlines?

Deloitte Case Interview (questions, process, prep)

Deloitte interviews are pretty challenging compared to regular interviews at large companies. The questions are difficult and the interview format is specific to Deloitte.

But the good news is that with the right preparation it can actually become relatively straightforward to succeed at a Deloitte interview. We've put together this ultimate guide to maximise your chances of success.

Here's an overview of what we'll cover.

• Introduction to Deloitte
• Interview process
• Regular case interviews
• Group case interviews
• Fit and PEI questions
• Preparation plan

1. deloitte consulting is bigger than mckinsey + bcg.

Deloitte is a force to reckon with in consulting. In 2022, it generated ~$26bn in revenue from its consulting business line. This makes it about as big as McKinsey, Bain and BCG combined.

Deloitte Consulting grew through a series of acquisitions. As a result, it's a collection of relatively independent firms operating under the Deloitte Consulting umbrella. Each member firm is managed by local partners who are responsible for their P&L. This is why you get more variation across different offices and regions than you do at a firm such as McKinsey.

Deloitte Consulting has three main practice groups you need to be aware of when applying:

1. Strategy and Operations (S&O) focuses on topics such as corporate strategy, supply-chain improvement, business model transformation, process improvements, etc.

2. Technology consulting focuses on digital strategy, delivery of IT programmes, cyber risks management, designing and building tech-based solutions for clients, etc.

3. Human capital focuses on topics such as organisation transformation, change management, corporate learning and development, diversity and inclusion, etc.

In 2013, Deloitte acquired Monitor which was initially founded by Michael Porter, the father of Porter's five forces . Monitor is now part of Deloitte S&O and that brand is particularly strong in North America.

The type of work Deloitte S&O does is very similar to what you would do at McKinsey , BCG or Bain . If you'd like to learn more about how Deloitte (and the other Big 4 firms) compares to the MBB firms, check out our MBB vs. Big 4 guide . 

2. Deloitte interview process

Your interview process with Deloitte will depend on whether you're applying as an experienced or early career candidate. There is also some variation by country, so we recommend that you ask your local HR contact at Deloitte for more details.

Below is an outline of the most common interview process and will be correct for the majority of candidates.

2.1 Early career candidates 

As an early career candidate you can apply online. You'll need your educational qualifications to hand, and you'll need to meet the minimum requirements.

The next step is an "immersive online assessment". Here you'll be asked to look at work scenarios and answer how you would respond.

Once you've completed it, you'll receive a "bespoke feedback report about your strengths and abilities".

If you fail the assessment, you'll hear back within a couple of days, but if you pass it may take a week or two before Deloitte contacts you - so in this case, no news is good news!

If you pass, you'll go onto the next assessment step: the "job simulation". You’ll answer questions across formats that include writing, video, multiple choice and ranking. Make sure you're dressed correctly and are in a quiet place before starting the simulation.

After you’ve completed the simulation, you'll get an email letting you know how you did within four weeks.

If successful you would then have a "Final stage assessment", which is a video interview with a senior consultant or an online group exercise. This would be the last step in your interview process.

Click here for more information on the interview process for early career applicants.

2.2 Non-early career candidates

If you're an experienced candidate, or at least not an undergraduate or recent graduate, the interview process will probably consist of three steps:

• Resume and cover letter screening
• First round interviews
• Second round interviews

2.2.1 Resume and cover letter screening

First, recruiters will look at your resume and assess if your experience matches the open position. This is the most competitive step in the process—we’ve found that 90% of candidates don’t make it past this stage.

You can use  this free resume guide  and this  free cover letter guide  to help tailor your application to the position you’re targeting. 

And if you’re looking for expert feedback, you can also get input from our  team of  ex-MBB recruiters , who will  cover what achievements to focus on (or ignore), how to fine tune your bullet points, and more.

2.2.2 First round interviews

Your interviewers at Deloitte will consist of a mix of senior consultants, managers and partners. First round interviews may be done in person or via video or phone call. They usually consist of:

• one behavioural interview (30 to 45mins)
• one or two case interviews (30 to 45mins each).

This is quite similar to what you could expect at other consulting firms.

2.2.3 Second round interviews

Second round interviews are similar to first round interviews, though the line of questioning can be a bit tougher. Your final interview is usually with a hiring partner, and before that you may face a group case interview.

• One behavioral interview (30 to 45mins)
• One case interview (30 to 45mins)
• One group case interview (45mins - 1hr)

Now you've seen an overview of the interview process, let's take a detailed look at regular case interviews and group case interviews at Deloitte, and how you should prepare for them.

3. Deloitte case interview questions

Case interviews at Deloitte are candidate-led. The style is therefore similar to what you will experience in a BCG case interview or a Bain case interview . Our research and experience tells us that there 7 types of questions you need to prepare for in candidate-led case interviews:

• Framework development
• Framework exploration
• Quant question – Data provided
• Quant question – No data provided
• Creativity question
• Recommendation

You can learn more about case interviews and how to prepare in our free case interview guide . One unique thing about Deloitte case interviews is that they will occasionally (but not always) give candidates written materials and a few minutes to review before they start the interview. This type of scenario requires the kind of skills you could learn in our free written case interview guide .

Deloitte has produced some very useful material to help candidates prepare. Take a good look through this practice case .

Deloitte has also shared some example case studies that you can work through interactively:

• Deloitte case study 1: Federal health agency needs to respond to Ebola epidemic (Advanced)
• Deloitte case study 2: Talent management for the Civil Cargo Protection Bureau (Advanced)
• Deloitte case study 3: Engagement strategy for a huge federal agency (Undergraduate)
• Deloitte case study 4: Recreation Unlimited, a global apparel and sportswear company, must reverse declining market share (Undergraduate)
• Deloitte case study 5: Federal benefits provider needs to formulate its 10-year vision (Undergraduate)

All these strategy cases can all be found on Deloitte's case interview prep tool, along with some Application Program Analyst cases and Business Technology Solution cases.

4. Deloitte group case interview

As mentioned above, Deloitte also uses group case interviews in its final round. Here is the key information you need to be aware of for this interview format:

• Candidates get divided into groups of 4 to 6
• Each group is given information about a case (i.e. a client facing a problem)
• You are given 10mins to review the materials by yourself or with another person in your group
• You are then asked to discuss a few questions about the case for 20mins with the rest of your group in front of your interviewers
• The interviewers will ask a few questions to the group for 15 to 20mins

This type of case mainly tests your ability to work with others. Interviewers won't intervene during the group discussion. They will just observe the group dynamics and mark each participant based on how they are contributing to the discussion.

Here are the top 3 things you should aim to do in your Deloitte group interview:

• Speak with a purpose. At the beginning of a group discussion, a lot of candidates will want to speak their mind as they know participating is important. But participating is not enough. The QUALITY of your input is crucial. Sometimes, it's better to let two or three people get the discussion started. And to then make a very thoughtful point based on how they started the discussion. Focus on the quality of your input, not the quantity.
• Involve everyone. Another tip that's easy to apply is to keep an eye on who's participating in the conversation and who's not. If you identify a member of the group who's struggling to make themselves heard, you should not hesitate to help them be heard by saying something like: "We haven't heard everyone's opinion on this yet. John, Rebecca what do you think?"
• Summarise. Finally, at the end of the 20 minutes group discussion it's a good idea to summarise the different points people have made. This will position you as the person bringing everyone together and making sure all candidates are on the same page. It is something some partners in consulting like doing with clients in real life and will therefore reflect positively on you.

And the top 3 things you should really avoid doing :

• Looking nervous. Group interviews is the time to put your poker face on. Everyone is stressed in a group interview. But you need to try your best to come across as confident. A good way to do this is to focus on basic body language: look at people in the eye, sit confidently, don't cross your arms, etc.
• Interrupting others. Consultants need to be client-friendly, and interrupting someone in a discussion is not client-friendly at all. You should listen carefully to what others are saying. Try to have a genuine interest in what they think. Before making your point, summarise their point to show that you understand what they mean.
• Dominating the conversation. Finally, some candidates are so eager to participate in the conversation that they end up completely dominating the rest of the group without realising it. A good tip to avoid this is to keep an eye on how much time you talk. If you are in a 5-person group you should aim to speak 20% (1/5th) of the time and really no more than 25%.

Your performance in regular and group case interviews will play a big role in Deloitte's decision to give you an offer. If you'd like to learn more how to approach group interviews, check-out our  separate detailed  guide to group case interviews.

5. Deloitte behavioral questions

Behavioural interview questions asked at Deloitte fall into two categories:

• Fit questions. These are generic questions such as “ Why consulting? ” or “ Why Deloitte? ”.
• Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you led a team through a difficult situation.” Or “Tell me about a time where you had to manage a team conflict”

Here are the top 5 fit and PEI questions you should prepare for at Deloitte and other consulting firms.

Top 5 fit questions:

• Why Deloitte?
• Why consulting?
• Walk me through your resume
• Tell me about something not on your resume
• Tell me about your greatest accomplishment

Top 5 PEI questions. Tell me about a time when ...

• You led a team through a difficult situation
• You worked in a team and had to manage a conflict
• You had a disagreement with a colleague / boss
• You had to change someone's / a group's mind
• You overcame a really difficult challenge

Don't fall into the trap of under-preparing for these types of questions. While they may seem easier than the case interviews, they are extremely important to get right.

You’ll need to prepare several ”stories” or “examples” from your personal and professional experience to demonstrate that you have the traits that Deloitte is looking for.

6. Deloitte case interview preparation plan

Now that you know what to expect in Deloitte interviews, let's discuss the steps you should take to prepare.

6.1 Learn the case interview essentials

The best starting point for your case interview prep is our case interview prep guide . It'll take you through all the different types of questions you may be asked in your case interview, show you how to draw from different frameworks to structure your answer, and give you example cases to practise with.

6.2 Become really confident at maths

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. However, during your Deloitte  interviews, you will be expected to quickly perform accurate mental maths. 

In order to do this, it’s essential to know the formulas for common metrics, like return on investment or breakeven point. And it’s also helpful to know a few maths shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths . 

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

6.3 Research the company

Deloitte interviewers want to hire candidates who are deeply motivated to work for their firm. Make sure you're up to date in the latest developments in the area of the company you're applying to join. Here are some useful links to get you started:

• Deloitte's insights page
• Deloitte's selection of business podcasts
• Financial Times' news articles on Deloitte

In addition, do some networking so that you can show you've made the effort to reach out to current staff.

6.4 Do mock interviews

How you solve each case is important, but your interviewers will also be evaluating how you COMMUNICATE your answers. It's important to speak in a structured way that makes it easy to clearly understand your points.

The best way to hone your communication skills is to practise interviewing out loud, and you can do that in three main ways:

• Interview yourself (out loud)
• Practise interviewing with friends or family
• Practise interviewing with ex-interviewers

To help you with this process, here is a  broad  list   of consulting interview questions  you can practice with.  Practising by yourself is a great way to get started, and can help you get more comfortable with the flow of a case interview. However, this type of practice won’t prepare you for realistic interview conditions.

After getting some practice on your own, you should find someone who can do a mock interview with you, like a friend or family member.

We’d also recommend that you practise 1-1 with ex-interviewers from Deloitte . This is the best way to replicate the conditions of a real case interview, and to get feedback from someone who understands the process extremely well. Meet our Deloitte ex-interviewers who’d love to work with you.
