I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in May 2020
Interview
Scheduled a phone call with an engineer on the team. They were polite and asked relevant questions to the job role. Questions included personal, technical, and scenario. Usually it would be two phone interviews with different engineers on the team and then an interview at their office.

I applied online. The process took 1 day. I interviewed at Jane Street
Interview
Three mandatory phone screens, one or more in-person interviews.
The interview process is very extended. It could be weeks between phone screen sessions, they there are at least 3 phone screens.
I felt the interview process was more self-gratifying for the interviewer than anything else. He/she told me about the great advantages the company has to offer, the fact that this person has been there for more than a decade and that they would never leave.
They also spoke about how they use their own money for quantitative trades, and that they are a very "unique" and different "shop" than everyone else on the block.
