An AI interviewer runs a full case, reacts to your structure and your math, and grades how you did.
Interview Prep includes technical and behavioral rehearsal questions, as well as drills and lessons.
The interviewer opens a case and hands you the prompt. You lay out your structure and start working, the same as a real round.
You ask for data, size the market, and work the math. The interviewer reveals figures as you earn them and pushes when your logic slips.
Your structure, your math, and your recommendation are graded at the end. You see where the numbers held, where they broke, and what to tighten.
It stays in role the whole way through. It hands you the data when your structure has earned it, holds the line when you misread an exhibit, and keeps the clock on the math.
A sample moment from the room:
Interviewer: Take me through how you would size the market.
You: About 40 billion units a year, so roughly 40 billion in revenue.
Interviewer: Check your units. You counted households as people, and your revenue per session as revenue per attendee.
The interviewer hands you exhibits and holds you to the numbers. Here is one, from a real case in the app.
Northlake chain P&L, annual ($M)
| Last year | This year | |
|---|---|---|
| Ice revenue | $5.59M | $5.49M |
| Concession profit | $1.49M | $1.37M |
| Variable cost | $1.68M | $1.74M |
| Fixed cost | $2.80M | $3.20M |
| Profit | $2.60M | $1.92M |
Concession margin stable at 60%.
Profit fell 26 percent in a year. The interviewer wants the two dollar figures behind it, and grades each against a tolerance band, in the format the report returns:
Check 1: the mix shift
Your number: 290,000. Expected: 288,000, within 10 percent.
Check 2: the new site's drag
Your number: 400,000. Expected: 273,160, within 15 percent.
This matches a known wrong-method result.
Up to three a day. The AI interviewer runs a full case, reveals the exhibits as you work, and grades your math and your recommendation.
Rehearse structuring, sizing, and case math, and get graded against the key points.
Rehearse your fit answers for the personal experience interview and build a story bank you can re-aim per question.
