I applied online. The process took 2 weeks. I interviewed at Jane Street (Cambridge, England) in Oct 2025
Interview
I had a phone interview where we went over a technical problem. The interviewer described the problem in a very clear and well-defined way. I was allowed to code in any language I wanted to (ended up going with python). The response times are good, this company will not ghost you.
Self introduction. Describe past experience with skills relevant to the job. Live coding of several algorithms as part of one combined software system in a remote call with a full-time engineer
Interview questions [1]
Question 1
Have you had experience with functional programming?
had a video call with a recruiter, was able to provide times and they chose one. The recruiter was very nice and helped when I got stuck on the problem
