They asked probability questions and game theory questions, you had to solve them on the spot. There were about 3 different questions and they got progressively harder. There were no behavioural questions, just technical problem solving.
Questions d'entretien [1]
Question 1
You flip a coin against me and whoever gets more heads wins. If you can bet money after each coin flip, what is the optimal betting strategy
The process began with serveral online tests for maths and logic. They gave a personal interview to get to know the candidate better and evaluate fit for the company/role, then held a technical interview covering maths and logic problems.
J'ai passé un entretien chez Jane Street (Hong Kong)
Entretien
Fun and filled with unexpected questions. The questions rely on fast thinking and fast calculations, and sometimes intuition because there is no sufficient time for me to work through the whole problem.
We started with a bit of small talk, followed by some probability questions. Ended with some basic algebra questions, Make sure to ask questions if you have any. Good experience, feels like the interviewer was trading.
