The drunk passenger

100 passengers board in order for 100 assigned seats. Passenger 1 lost their boarding pass and sits in a uniformly random seat. Each later passenger takes their own seat if it's free, otherwise a random free seat. What is the probability that passenger 100 ends up in their own seat?

Why it works

Interview-grade questions, by format
A large bank of probability, brainteaser, market-making and DSA questions, organised by the interview formats and roles they are modelled on.
Practice under pressure
Server-timed simulators modelled on commonly reported assessment formats - a penalty-scored probability OA, the mental-math blitz, sequences, number-box, an estimation sprint, a which-is-larger number-sense drill, and a flashing mental-ledger - with instant scoring and leaderboards.
Learn by doing
Drills, interactive skill games, and curated format tracks instead of passive reading. Every attempt is tracked, so you can see your progress by topic.
End to end
From skill-building to format-specific tracks to progress tracking, all in one place - built to take you from interested to offer.

951 curated probability, brainteaser, stats, market-making and DSA questions, each with progressive hints and a worked solution in clean LaTeX. All of them are free, with auto-checked answers.

Every track is free.

Interactive games

Five skill trainers for the quant interview - snap EV calls, calibration, edge detection, Kelly bet sizing, and make-a-market. Outcomes are random so nothing's memorisable; a skill rating climbs as you improve, with the optimal reasoning revealed after every play.
