Very enjoyable, problems mostly focused on probability, game theory, market making games. Got rejected third round on a difficult game theory question, speed and clarity of thought is key in these interviews.
I applied online. I interviewed at Jane Street (London, England) in Nov 2025
Interview
The interview went well and easily, but I was nervous, so I answered quickly and made small mistakes. They gave me a chance to correct myself. However, the interview ended quickly, and it seems that I am not a good fit for them.
