Case Interview Guide: Consulting and Analytical Interview Preparation
Introduction
Case interviews are used primarily by management consulting firms and increasingly by other analytical roles. Candidates are presented with business problems and evaluated on their problem-solving approach rather than the specific answer.
Case interviews test structured thinking, quantitative analysis, business acumen, and communication skills. Success requires understanding frameworks, practicing quantitative analysis, and maintaining composure under pressure.
