How is the voice case different from a generic AI chatbot?

You speak, it listens. It probes weak structure with follow-ups, shares a P&L exhibit mid-answer, and grades you on what MBB interviewers actually score, calibrated turn-by-turn with active McKinsey, BCG and Bain consultants.

Why do the cognitive tests matter so much?

Solve, Casey and SOVA decide who even gets an interview. Fail a test and you never meet a partner, yet most prep tools ignore them entirely. We rebuilt each one to mirror the real format and timing.

What's inside a lesson?

A short video explaining the concept, the idea, an example, the traps, then a worked example annotated line by line, then a timed drill. 82 lessons across three learning paths.

Can I try it before paying?

Yes, the diagnostic and one full lesson are free, no credit card. Full AI interviews run on a one-time plan (no subscription and no auto-renewal): you pay once and get access for a fixed window.

CasingLab | Realistic Case Interview Practice for MBB

“I used the AI case interviews almost every day before my interviews. What impressed me most was how natural they felt. The interviewer challenged my reasoning, asked follow-up questions when my answers weren’t clear, and adapted the discussion just like a real interviewer. The feedback after each case was incredibly detailed and gave me very concrete points to work on. It became the most valuable part of my preparation.”

“I had practiced with friends before, but I improved much faster once I started using the AI cases on CasingLab. Being able to jump into a case whenever I had 30 minutes made a huge difference. The feedback wasn’t generic — it highlighted the small things I would never have noticed on my own. By the time I interviewed, I felt much more comfortable handling unexpected questions.”

“What I liked most was that I could prepare for both the online assessments and the case interviews on the same platform. The assessment practice felt very realistic, and the AI interviewer helped me stay consistent between live mock interviews. Having detailed feedback after every session made my preparation much more structured.”

“I was mostly worried about the BCG online assessment because it’s difficult to find realistic practice material. CasingLab gave me a much better idea of what to expect, and I kept using the AI case interviews afterwards. The combination of realistic assessments and detailed feedback made me feel much more confident throughout the recruitment process.”

“The McKinsey Solve Game was one of the reasons I signed up, but I ended up using the AI case interviews even more. After each session I received detailed feedback on my structure, communication and overall approach, which helped me improve much faster than I expected. By the time I reached my interviews, everything felt familiar.”
