Applied online and got contacted by HR to schedule a phone interview with a trader. It lasted about 30 mins and the guy was pretty nice. The interview itself was purely technical and focused on probability and game theory.
If you go through the reviews here you will probably not get any unexpected types of questions.
Interview questions [1]
Question 1
Nothing unexpected. Dice probability questions and some brainteasers.
- What is expected value of two dice
- If I offered you a game where i get X dollars for outcome set A and you get Y dollars for outcome set B would you play?
I interviewed at Jane Street (London, England) in Jan 2026

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
