Case interviews are structured problem-solving exercises where candidates analyse a business situation, e.g. 'How would you double this company's revenue?' They are primarily used in: strategy consulting (McKinsey, BCG, Bain), management consulting, investment banking, venture capital, and tech product management. Formats include: Market Sizing (estimating market size), Profitability (analysing profit decline), M&A (evaluating acquisitions), and Growth (developing growth strategies). According to IAB and LinkedIn: Case interviews are less common in Germany than in the US/UK but are standard in consulting. Preparation resources: Victor Cheng, Case in Point, BCG Practice Cases (all freely available). ISO 10667 on validity: Case interviews have higher predictive validity than pure knowledge tests when they are job-related.
