What is a case interview?
A case interview is a consulting interview format where the candidate works through a business problem, structures an approach, analyzes information, performs calculations, communicates reasoning, and makes a recommendation.
What do case interviews test?
Case interviews test structured problem-solving, business judgment, quantitative thinking, communication, creativity, synthesis, and the ability to lead a problem-solving conversation.
How should I start preparing for case interviews?
Start by learning how case interviews flow, then practice structuring, clarifying questions, mental math, exhibits, synthesis, and full cases out loud. The fastest prep is usually a mix of fundamentals, targeted drills, and realistic mock cases.
How can I practice case interviews alone?
Practice alone by reading a prompt, summarizing it out loud, asking clarifying questions, taking time to structure, presenting the structure, doing timed math or exhibit work, and recording yourself. CaseLab helps automate this with live voice cases and scored feedback.
How many case interviews should I practice?
There is no universal number. Candidates should practice enough to build fluency across case types and remove recurring weak spots. Quality, feedback, and targeted repetition matter more than raw case count.
How do I know if my case structure is good?
A good case structure is tailored to the objective, logically separated, practical to analyze, and clear enough for the interviewer to follow. It should show where you would start and why.
What are good clarifying questions in a case interview?
Good clarifying questions define the objective, scope, metric, constraints, business model, and any ambiguity that would change the analysis. They are not a long list of generic background questions.
How do I get better at case math?
Practice explaining your setup before calculating, keep units clear, sanity-check the answer, and connect the number back to the case decision. The goal is not only accuracy, but calm and useful quantitative reasoning.
How do I improve chart and exhibit interpretation?
Start by naming what the exhibit shows, identify the main trend or comparison, explain why it matters, and connect it to the case objective. Avoid reading every number without drawing an implication.
How do I give a strong final recommendation?
Lead with the answer, support it with two or three reasons, mention the most important risk or next step, and keep the recommendation tied to the original client question.
Should I memorize case frameworks?
Memorized frameworks can help beginners learn common business issues, but strong candidates tailor the structure to the specific case. The structure should sound like an action plan for solving that client's problem.
Is peer practice enough for case interviews?
Peer practice can be very useful, especially for live communication. Its weakness is inconsistent feedback quality. Candidates often need a mix of peer mocks, expert feedback, and targeted drills.
How do I know when I am interview-ready?
You are closer to interview-ready when you can lead cases out loud, structure unfamiliar problems, handle math and exhibits calmly, synthesize clearly, recover from pushback, and repeat that performance across multiple case types.
