A case interview is a job interview in which the applicant is given a question, situation, problem or challenge and asked to resolve the situation. The case problem is often a business situation or a business case that the interviewer has worked on in real life.
After the applicant is given information about the case, the applicant is expected to ask the interviewer logical and sequential questions that will enable the applicant to understand the situation, probe deeper into relevant areas, gather pertinent information and arrive at a solution or recommendation for the question or situation at hand.
Case interviews are mostly used in hiring for management consulting and investment banking jobs. Firms use case interviews to evaluate analytical ability and problem-solving skills; they are looking not for a "correct" answer but for an understanding of how the applicant thinks and how the applicant approaches problems.[1]
During case interviews, interviewers are generally looking for the following skills:[2]
Candidates are often asked to estimate a specific number, often a commercial figure (such as market size or profitability). Candidates are expected to demonstrate reasoning rather than to produce the exact answer.[3]
A case interview can also be conducted as a group exercise. Here several candidates are given some briefing materials on a business problem and asked to discuss and agree upon a solution. The interviewers normally sit around the exterior of the room as silent observers. They assess candidates' communication and interaction as well as analytical thinking and commercial awareness. Interviewers "red flag" candidates who try to dominate the conversation; consultants work in teams so it's important to be a team player.[4]
