This is the full case library — 73 technology consulting cases across 8 firms: McKinsey, BCG, Bain, EY, PwC, Deloitte, Accenture and Kearney. Each one is built from a real briefing, not a generic prompt, and runs live against an AI interviewer trained on that firm's actual style — McKinsey's hypothesis-first pyramid thinking, BCG's framework-anchored rigor, Bain's results-obsessed plain speech, and so on. You pick a firm or a technology topic (cloud, AI, cybersecurity, digital transformation), read the brief, and the interviewer takes it from there — pushing back when you hand-wave, scoring your structure, math, and recommendation at the end. Every case is free to browse; the free tier includes a full practice run, and paid access unlocks the complete library plus scored reports across every session. Start with whichever firm you're actually interviewing with, or browse by topic below if you're still deciding.
