Phone call with some maths questions. Cannot use a calculator or paper and pen to write and solve the questions. Be well prepared to do mental exercises for the interview and review probability theory and combinatorics.

Question 1
How many people in a group so that at least two of them have a birthday on the same month?
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.
