I applied online. The process took 1 week. I interviewed at Jane Street
Interview
Applied online, heard back a few days later to schedule a video interview. The first round was some puzzles on probability and dice rolling. Interviewer was kind and answered clarifying questions. Did not make it past the first round.
Interview questions [1]
Question 1
Compare expected value of median and mean of two dice rolls, decision-making dice rolling game
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.
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.
