Entrevista
Only made 2 rounds, pure problem-solving/ brainteaser interview. Very little / no behaviourals. Interviewer was friendly, but got straight into the brainteaser questions. Very quick to respond when passing to next round, slow response for rejection.

Ball game
3 buckets, each with one space. Every time you throw the ball, you are guaranteed to hit one bucket. (if it is filled, it bounces out). Every ball in - +1, every ball out, -1 You have 2 balls, what is the expected gain?

Easy first round, they time how many questions you can get right and move you through the stages based on that. I only got through the initial assessment, which was extremely hard but I managed to do well. My resume also passed through but I'm from UT Austin so they definitely recruit other than just Harvard and Stanford.

Statistics Questions and Probabilities. They build more questions on top of the previous questions by adding more caveats and details.

Very difficult, nice location in London, a good trip
People are very nice but demanding and the interview ended very briefly
After applying next year got immediately rejected on CV screening, so I think that the cooldown period is real
