I applied online. The process took 3 weeks. I interviewed at Jane Street (New York, NY) in Jul 2025
Interview
After I submitted the initial application and my resume was reviewed, they got back to me to schedule a live call interview some time in the following two weeks.
The first interview was a call with a current software engineer, and we went through a single programming problem together in around an hour. He didn't run my code at all, but suggested possible refinements or flagged issues where applicable.
I was able to come up with the correct solution during the interview, but did not progress to the next round.

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.
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
