The problem
The theory is long and inconsistent.Every source has its own framework, and few tell you what to actually do in the room.
Practice depends on a partner.Hard to arrange if you work, slow because you take turns, and only as good as their feedback.
Without a plan, practice is random.You cannot see which case types, industries or skills you have not covered yet.
A session, end to end
Case type, industry, difficulty, language — drawn fresh from the library, never one you have already practised.
Make a weak point and it challenges you, the way an MBB interviewer would. It won't hand you the answer.
The same kind of tables and charts you'll get in an interview. Find the insight and say what it means for the client.
After every completed case: what went well, where you lost points, what a strong answer looked like, and one thing to fix next time.
Your progress shows which case types, industries and levels you have covered, and points you to the next case, so your practice spreads across everything an interview can throw at you.
“I used InterviewLab almost every day in the weeks before my interviews. The cases felt close to the real thing, and the feedback showed me exactly what to fix. Simple, and it worked.”
The library
Quality, quality, and quality: 350+ cases across every case type and industry, from easy to hard.

Exhibits to read, an AI interviewer that pushes back, written feedback at the end.
Market sizing
market sizing cases across five structures, practised as a discipline of its own.
Interview in
1,000+ real coaching sessions behind the library. The cases are the kind interviewers actually give.

Everything around the interview
Business Case, Market Sizing and Behavioural: three guides written on one method, so what you read is what you practise.
Short videos beside the guide sections, each one solving a case step by step, so you see the method used before you use it.
Your coverage across case types, industries and levels, and a suggestion for the next business case to practise.
Weighted average, margin and markup, breakeven, payback, large numbers and percentage change. After each answer, the worked answer step by step.
Why practise here
A general AI chat can talk about cases; it does not run one.
| With a general AI chat | With InterviewLab | |
|---|---|---|
| Who runs the case | You do: you write the prompt and keep it on track. | An AI interviewer, through a real case structure and best-in-class voice capabilities. |
| The case | Made up as you go, so the numbers may not add up. | 350+ written cases (240+ business, 110+ market sizing), with exhibits to read. Never one you have already seen. |
| When you hesitate | It tends to solve the case for you. | It challenges the weak point and does not hand you the answer. |
| Feedback | General comments, if you ask for them. | A written feedback report, phase by phase, at the end of every completed case. |
| What next | Nothing tracks which case types you have covered. | Your progress page and a next-case suggestion (business cases). |

No. The interviewer is an AI. It runs the case like a real interviewer: it asks for your structure, shares exhibits and data, and pushes back when your reasoning has a gap.
No, and it shouldn’t. Use it for volume and to find your weak spots; use a partner for the pressure of a live round. Most candidates who get offers do both.
