Five cases. One clear path.
Work through them in order. Each case builds on the last: harder problems, longer answers, less hand-holding. By the end you'll be structuring and writing like the real thing.
These are self-paced walkthroughs, not the AI. Every step comes with a written breakdown and a model answer to compare yours against — nothing you write here is graded. Free, unlimited, no account needed. For a live interview that reacts to what you say, that's Practice Mode — a separate library of 12 cases, capped at 5 sessions a week.
How the cases are structured.
Each case shifts the balance from multiple choice toward freewrite — so you build up to the real thing gradually.
Why we push you toward freewrite.
Early on, multiple choice lets you see what good answers look like — the structure, the vocabulary, the reasoning. You learn the shape of a strong response without having to produce one from scratch.
In an actual case interview, nobody gives you options. You have to structure your own answer, pick your own words, and defend your reasoning. That's what the later cases train you for.
Freewrite sections are just for you to structure your thoughts — there's no grading, no right or wrong. Write out your thinking the way you would in a real interview: break the problem down, lay out your logic, and commit to a direction.
Once you submit, you'll see your answer side by side with the recommended answer so you can compare your structure, reasoning, and depth against what a strong response looks like. Follow the recommended flow each case gives you — it mirrors how top candidates actually walk through these problems.
Hit a term you don't know? Look it up. Don't skip it. These cases use real consulting and business language on purpose — the more you Google unfamiliar terms now, the more fluent you'll be when it counts.
Start at the top. Work your way down.
Each case is harder than the last. Don't skip ahead — the early ones teach patterns you'll need later.
