Interview
Give one or two game theoretical problems to optimize my profit or minimize loss. As the round proceeds, the difficulties get harder. Interviewer gives you few clues when you are lost. Need to keep track on how you are approaching.
Very good interview process, interviewers are polite and engaged, and happy to help you get unstuck during the problem solving process. Problems are tough but reasonable, very interesting to do
I applied online. I interviewed at Jane Street (New York, NY) in Oct 2025
Interview
Round 1: Basic probability questions. Just EV stuff, find strats that maximize EV
Round 2: Same as Round 2, questions are a bit more challenging
Round 3: Harder than R2, this time expect some game theory too (knowing what the Nash equilibrium is, etc). The question will be more open-ended and challenging, so make sure you clarify what exactly the interviewer wants. The interviewer will work with you and guide you in the right direction.
I was rejected after Round 3 even though I solved the question with hints, but Round 4 is in-person and they make you fill out an immigration form if you're outside the US so make sure you can enter the states for R4.
