Interview Tips

Preparing for case interviews

The final round for CCG involves three 10-minute interviews – a behavioral interview, a quantitative case, and a qualitative case. We encourage you to read the tips below and walk through the practice cases you can find under the recruitment tab.


What is a case interview?

In a case interview, the candidate is provided with a detailed situation, problem or challenge. The interviewee is asked to analyze the problem and to come up with a solution. It is a great way to give candidates an inside look into the type of work consultants do. It also allows employers to get a sense of a candidate’s problem solving and presentation skills. The case is a key factor in consulting interviews and is the cornerstone of the CCG recruiting process.


Here are some tips to keep in mind:

Ask Questions from the start:

  • In the beginning, you’ll be given important information about your case
  • Be sure to listen carefully to the prompt and take diligent notes
  • When the interviewer asks if you have any questions before proceeding – It’s time to ask clarifying questions

Take detailed notes:

  • During the interview, you’ll have to keep track of a lot of information and it’s helpful to have it laid out in front of you
  • Structure is an important part of the interview and notes will help you keep yourself organized

Get comfortable with numbers:

  • Mental Math, especially during the quantitative case, is key in going from the problem to your final recommendation
  • Make sure you are familiar with basic arithmetic, but you can skip the calculus for now – you won’t run into math that difficult
  • When in doubt, feel free to write out your problems. It’s better to take your time and get the problem right than to answer quickly but incorrectly

Finally, practice, practice, practice:

  • It’s important to get familiar with case interviews by working through as many of them as you can
  • For example cases, be sure to go through the ones included on the CCG website, they are final round questions that we have used in the past
