Deloitte Case Interview

The largest and arguably most prestigious of the Big 4 Accounting firms, Deloitte also generates billions of dollars in revenue from its consulting services. Many consider Deloitte to be a leader in the second tier of consulting firms right after McKinsey, Boston Consulting Group, and Bain. If you have any desire to join the firm, you will of course have to pass the Deloitte case interview.

Though case interviews broadly follow similar structures, each consulting firm does things a little differently. In this article, we’ll be going over the unique aspects of the Deloitte case interview. In addition we’ll give Deloitte interview case study examples for continued learning.

Deloitte Case Interview

The 3 Consulting Groups at Deloitte

First of all, it’s important to know that Deloitte’s consulting practice is broadly broken down into three groups: Strategy & Operations, Technology, and Human Capital. Depending on the group you are going for, your case study interview will vary drastically.

Here is some information about each group:

Strategy and Operations (S&O)

Focuses on topics such as corporate strategy, supply-chain improvement, business model transformation, and process improvements

Technology

Focuses on digital strategy, delivery of IT programs, cyber risks management, and designing and building tech-based solutions for clients.

Human Capital

Focuses on topics such as organization transformation, change management, corporate learning and development, and diversity and inclusion

The Deloitte Recruiting Process

Your Deloitte case study interview will also depend on the part of the recruiting process you are in. The process typically involves 3 steps:

  1. Resume / Cover Letter Screening
  2. 1st Round Interviews
  3. 2nd Round Interviews

The 1st round of interviews usually involves one 30-45 minute behavioral interview and one or two 30-45 minute case interviews. Your interviewer will be a consultant or lower level manager.

The 2nd round of interviews is notably different at Deloitte compared to other consulting firms. Typically, candidates will go through one behavioral interview, one case interview, and a group case interview.

The One-on-One Deloitte Case Interview

The most important thing to know about the individual, one-on-one case interview for Deloitte is that it is candidate-led, similar to BCG and Bain. This means that you will be in the driver’s seat throughout the case and should be constantly asking questions, probing for data, and summarizing your findings with as little direction as possible. Don’t expect a bunch of Deloitte case study interview questions teed up for you. Rather, take charge and show initiative in asking the case study interview questions to the Deloitte personnel.

Your case interview will be based on the group you are recruiting for. As a result, you can expect the case study to be based on a real previous project the group has worked on. During your preparations, it is important that you practice cases relevant to the respective group you are interviewing for, as each type vastly differ from one another.

Besides that, the case interview will be pretty standard. Here are some of the pieces of advice from Deloitte’s website:

  • Understand the issue
  • Ask clarifying questions as needed
  • Identify the underlying assumptions
  • Summarize specific issues and findings
  • State your recommendations
  • Outline next steps and expected results/impacts

The Deloitte Group Case Interview

The group case interview at Deloitte is the part of the recruiting process that is most challenging to prepare for. This is simply because it’s difficult to simulate a group interview, while of course practicing mock one-on-one case interviews requires just one other person.

During the group case interview, you and 3-5 other candidates will be given a case study to examine. You are given 10 minutes to review the materials and then asked to discuss questions about the case for 20 minutes with the rest of your group. Interviewers from Deloitte will be watching the whole time and will conclude the interview by asking the group questions for another 20 minutes.

This part of the interview is markedly different from other consulting firms. Your goal should not be to outshine or dominate the conversation – instead, do your best to show a collaborative spirit while speaking with a purpose when it’s your turn to talk. Deloitte places a high emphasis on teamwork and culture fit, so it’s important to show that you can be a great colleague.

Deloitte Interview Case Study Examples

Deloitte provides a handful of practice cases that are helpful depending on the consulting division you are interested in. These are actual Deloitte interview case study examples, and are provided through the Deloitte or third party websites.

Deloitte Behavioral Questions

Beyond the Deloitte case study interview, you must also be prepared for behavioral questions. Here are the most common ones to prepare for:

  • Why Deloitte?
  • Why consulting?
  • Walk me through your resume
  • Tell me about something not on your resume
  • Tell me about your greatest accomplishment
  • Tell me about a time when you had a disagreement with a colleague / boss
  • Tell me about a time when you overcame a really difficult challenge
  • Tell me about a time when you worked in a team and had to manage a conflict
  • Tell me about a time when you had to change someone’s / a group’s mind
  • Tell me about a time when you led a team through a difficult situation

Concluding Thoughts

The Deloitte recruiting process is no cakewalk. The firm spends an enormous amount of money recruiting top candidates around the world in order to maintain its culture of excellence. However, with the right preparation and knowledge about the process, you can give yourself a leg up versus other candidates. To that end, we hope you found this article helpful!
