11 Interview Question Types and How to Prepare

9. Case / Problem-Solving Questions

Case or problem-solving questions are common in consulting, product, and certain business roles. Interviewers evaluate structured thinking, quantitative comfort, and clear communication. Start by clarifying the question and asking for missing data. Then outline a logical structure to explore the problem—segment the market, identify key drivers, or break the problem into manageable parts. Use rough math to check feasibility and state assumptions clearly. Practice with sample case prompts and get feedback from peers or career coaches. During the interview, narrate each step and keep the interviewer engaged with short summaries of your thinking. Avoid rushing to a solution without showing the steps that led there. Quick checklist: 1) Practice clarifying questions; 2) Use a consistent structure for problem breakdowns; 3) Practice light quantitative checks to support recommendations.
