I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in Sep 2023
Interview
It was a zoom interview as the first round. Was given a probabilistical puzzle and the interviewer asked step-by-step questions as I solve the problem. The problem was tricky but interviewer kindly led me into a good direction of thinking.
Interview questions [1]
Question 1
Probability puzzle. It seemed like they have a long list of puzzles and randomly choose one of them for each interviewee
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.
