Most preparation fails in the same predictable way

Candidates spend months consuming material and almost no time being tested under conditions that resemble the real thing. PartnerRound inverts that.

How most people prepare
Reading case books until the frameworks blur together
Practising with a friend who cannot tell you what you missed
Guessing how McKinsey Solve is graded
Finding out you are slow at maths during the real interview
With PartnerRound
Live cases where an AI interviewer interrupts and challenges you
Scored feedback on structure, maths, judgement and communication
A working simulation with both product and process scoring
Timed drills that track your speed and accuracy over weeks
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.

Nordwind Airlines · 14:22 remaining
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?
Playable simulations

The assessment games, rebuilt so you can actually practise them

Not screenshots and not a description: working simulations with the real constraint logic, so a wrong answer is wrong for the same reason it would be on the day.

Ecosystem Building
McKinsey Solve

Choose a location, then assemble a food chain that is terrain-legal, connected and calorie-balanced. Every rule from the real task is enforced, so a wrong answer is wrong for the right reason.

Sea Wolf
McKinsey Solve

Screen eight strains against hard site tolerances, where one failed rule is enough, then build the strongest legal treatment from the ones you accepted. Reject a strain you needed and the best blend stops being reachable.

Red Rock Study
McKinsey Solve

A timed research case in three phases. Pull the evidence that bears on the objective into your journal and leave the rest, run the calculations, then defend a recommendation. Every note you are shown is true and half of them change nothing.

Sustainable Futures Lab
McKinsey Solve

Rank competing climate initiatives against the client's stated criteria, respect the dependencies between them, then handle a stakeholder who disagrees with your order. Positions are scored exactly, as the real task counts them.

BCG Online Case

A complete case through a chat interface: structuring, maths, exhibit reading, hypotheses and synthesis. Each answer is typed against its own clock and scored on its own rubric.
