A live mock interview with an AI that stays in character, calls out weak answers, and shows you exactly where you lost points.
Interviewer: Senior Partner · Difficulty: Hard
Practice Mode is the live mock interview, capped at 5 sessions a week. Guided Cases are self-paced walkthroughs with written answers — no AI, no cap. Use them for different things.
The AI plays the client, not a coach. It won't open with "great question," won't narrate your technique, and won't warn you when you're walking into the case's trap. Give it a vague answer and it pushes back like a real interviewer would.
When the case closes, the Coach scores what you actually said against the points a strong candidate would have surfaced — and won't give you credit for a recommendation you never quantified. Then it drafts a report and deck from your own answers.
Separate from Practice Mode, and not AI-driven: five cases with pre-written answer breakdowns, a model answer at every step, and a finished report and deck at the end. Free, unlimited, no sign-in. Do these before you burn a mock interview.
Five steps, in order. Start knowing nothing, finish walking into the room confident.
Learn what a case interview actually is, what interviewers are looking for, and how CaseKit is structured. No prior knowledge needed.

A real Practice-Mode session on Brightline Outfitters, a Beginner-tier profitability case. Both artifacts below are what the system generated from this specific candidate's transcript — not a polished model answer. The gaps this candidate left are called out on both, exactly how they'd hit a partner's desk.
Both are generated from the candidate's actual transcript, the case's canonical facts, and the verified must-surface state — not a template. Gaps in the work show up as gaps here, not as a polished model answer.
The candidate diagnosed Brightline's margin compression as driven by two coincident cost-side moves — the warehouse lease renegotiation and the 18-month-old loyalty program — and recommended capping the loyalty reward rate while flagging the lease as a next-cycle renegotiation target. The diagnosis was structurally correct but under-quantified: both drivers were treated as roughly equal, when the underlying data puts loyalty discounting at ~70% of the decline versus lease at ~30%.
Brightline Outfitters is a 42-store outdoor apparel retailer with a growing e-commerce site. Total revenue has held roughly flat over the past two fiscal years ($182M → $185M → $184M) while operating profit has fallen by nearly 30%. Two operational changes coincide with the compression: a warehouse lease renegotiated for a longer term at a higher fixed annual rate, and a loyalty program that launched 18 months ago. The CEO's initial framing treated both as unrelated to the profit move.
Cap or tier the loyalty reward rate below the current 8%, and shift a portion of member value toward non-discount perks (early access, member-only events). Treat the warehouse lease as locked in for the current term; raise it as a renegotiation point at the next lease cycle.
