In this comprehensive guide, we’ll dive into the world of EY case interviews, equipping you with insider strategies, example questions, and proven tips to help you stand out from the crowd.

Understanding the EY Case Interview Process

Before we delve into the specifics, let’s first understand the typical EY case interview process. The process usually consists of the following rounds:

  • First Round: A 30-minute phone interview with a recruiter focused on behavioral or fit interview questions.
  • Second Round: Two 30-minute interviews conducted by Consultants or Managers. One interview is focused on behavioral or fit interview questions, and the other is focused on a case interview.
  • Third Round: Three 30 to 45-minute interviews conducted by Managers or Partners. One interview is focused on behavioral or fit interview questions, one is focused on a case interview, and one is focused on a group case interview.

It’s worth noting that the specifics of the interview process may vary slightly depending on the office or group you’re applying for.

Mastering the EY Case Interview

EY case interviews are candidate-led, meaning you’ll be in the driver’s seat, responsible for asking the right questions, probing for data, and proposing each next step to solve the case. Here’s a six-step approach to tackle any EY case interview:

  1. Understand the Case: Listen carefully to the case information provided by the interviewer, taking meticulous notes. Focus on understanding the context, the company, and the objective of the case.

  2. Verify the Objective: Ask clarifying questions to better grasp the business situation and problem. Confirm that you understand the case objective with the interviewer to ensure you’re on the right track.

  3. Create a Framework: Develop a framework to break down the complex problem into smaller, manageable components. A well-structured framework will help you organize your ideas and analysis.

  4. Develop a Hypothesis: Based on the information you have so far, formulate an educated guess (hypothesis) about the answer. This will guide your analysis and ensure you’re spending time answering the right questions.

  5. Test Your Hypothesis: Lead the direction of the case by asking for data, exploring qualitative questions, and continuously refining or adjusting your hypothesis as new information emerges.

  6. Deliver a Recommendation: Present your final recommendation, supporting it with the most important facts and reasoning. Consider including potential next steps or areas that require further exploration.

Example EY Case Interview Questions

To help you prepare, here are some example case interview questions that previous candidates have encountered at EY:

Preparing for the EY Group Case Interview

In addition to individual case interviews, EY incorporates a group case interview in the final round. This unique format assesses your collaboration and teamwork skills. Here’s what to expect:
