Case Interview Secrets: A Former McKinsey Interviewer Reveals How to Get Multiple Job Offers in Consulting

Read while preparing for a McKinsey case interview (the interview didn’t pan out), it still sharpened my hypothesis-driven thinking: MECE issue trees, answer-first structuring, 80/20 focus, and quick estimation. I’ve since applied those habits to research—breaking problems into testable drivers, separating hypotheses from execution details (e.g., site recruitment and stimulus-card design in the coffee-shop field study), and pressure-testing assumptions before data collection. Net effect: faster scoping, clearer models, and crisper synthesis for CB experiments and analytics.
