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.
Interview questions [1]
Question 1
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
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.
