I applied through a staffing agency. I interviewed at Jane Street (New York, NY) in Feb 2026
Interview
Zoom interview, and onsite interviews.
Overall, interviewers are friendly. I did encounter one person from the equity quant research team who came across as somewhat arrogant—he had strong intuition but seemed to lack basic vocabulary knowledge. I’m not sure if that was intentional.
There were also some last rescheduling changes, without any notifications until onsite meetings.
Interview questions [1]
Question 1
Usual questions within my field. Nothing surprising.
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.
