Why it works
Most preparation fails in the same predictable way
Candidates spend months reading and almost no time being tested under conditions like the real thing. PartnerRound flips that.

The AI interviewer
A case partner that has actually read the answer key
Every case in the library carries a private brief: the objective, the data, the intended structure, the maths with worked solutions, and the deliberate traps. The interviewer reasons from it, which is why it can tell you that your breakeven is wrong rather than nodding along.
Voice mode
Speak your structure out loud and hear the interviewer respond. The closest thing to the real room, in your browser.
It pushes back
The interviewer holds a private brief with the answer key, the data, and the traps, so it can challenge a wrong number instead of accepting it.
Scored on four dimensions
Structure, quantitative reasoning, business judgement and communication: graded separately, with the evidence quoted back to you.

Passenger numbers are up 18%, but operating profit has fallen 40%. How would you approach this?
I'd split profit into revenue and cost before exploring either. Revenue is volume times price; cost I'd split fixed versus variable, then convert everything to a per-flight basis. Given volume is up, I'd start on the cost side.
Good, start there. Ground handling cost per flight went from €940 to €1,610. What does that tell you?
That's €670 more per flight. Across 178,000 flights, roughly €119m of extra annual cost, which is more than the entire €61m profit decline.
Correct, and worth pausing on. If that single line exceeds the total decline, what must be true elsewhere?
