How it works

Three steps to interview-ready

01

Pick your target

Choose BCG, Bain, or McKinsey. Each path is built for that firm’s specific interview format.

02

Practice with AI

Solve cases with an AI that pushes back, drill math until it’s automatic, and build confidence under pressure.

03

Ace the interview

Walk in having already handled every type of pushback. Interview day is just another rep.

“I did 30+ cases with friends. None of them ever told me my structure was weak. The AI did — on turn 2.”

Questions candidates ask us

Which product should I start with?+
If you’re targeting BCG, start with BCG Prep ($99) — it’s live now with 10 AI chatbot cases. If you’re targeting Bain, the aptitude test bank launches in ~3 weeks. For McKinsey or general MBB prep, the AI Voice Simulator is coming in ~16 weeks. Math Drill is free for everyone — start there if you want a taste.
What if I’m targeting multiple firms?+
Products are independent — buy what you need. BCG Prep covers BCG-style cases, Bain Prep covers aptitude tests, McKinsey Prep covers PST-style cases. The Math Drill and AI Simulator work across all firms.
How is this different from casebooks or YouTube?+
Casebooks are static — you read a case and check the answer. CaseDrill’s AI pushes back on your structure in real time, catches gaps a casebook can’t, and debriefs you with specific feedback. YouTube shows you someone else solving a case; this makes you solve it.
What’s live now vs. coming soon?+
BCG Prep (Basic, $99/year) and Math Drill (free) are live today. Bain Verbal module launches in ~3 weeks. BCG VIP, Bain Comprehensive, and McKinsey + AI Sim are in development — see the roadmap above for ETAs.
Is there a refund policy?+
Lifetime tiers (BCG VIP, AI Sim Lifetime) come with a 7-day money-back guarantee. Monthly subscriptions can be cancelled anytime. Per-module and annual purchases are non-refundable. Full details on our Terms page.
