Jane Street Interview Questions

Application

I applied through a recruiter. I interviewed at Jane Street.

Interview

2x 1 hour phone calls and a 4hour Webex call
Low level technical questions for 1st line support.
Then higher level tech questions in next interview. A lot more getting to know about the company too.

Interview

Multiple rounds of brainteasers, probability questions, and game theory/strategy questions. All the interviewers were super friendly. First I was emailed by the recruiter, pretty quickly after applying, and then pretty quickly scheduled a first round. My entire process took about 6 weeks, and I got cut on the third round.

Interview

4+ phone screens, lots of probability and market making games, little to no behavioral beyond why trading/why JS. long final round, very hard, many rounds, not sure if they re-interview.

Interview

it was very short but good. asked many questions. I answered them all. overall a good interview. But wasn’t too fond of the place after the facts. Not too sad about not getting an offer.

I applied online. I interviewed at Jane Street.

Interview

Submitted resume and recruiter reached out for phone screen. First screen was pretty easy, all questions can be solved with basic probability knowledge combined with some clever thinking to "find the trick." Second round was much harder. I thought I did well but did no advance.

Interview

Couple phone calls with traders mainly technical stuff and basic resume walkthrough. Interviewers were friendly and really walk you through the problem rather than just expecting a question they look at your thinking which is nice.

Interview

Phone interview took 30 minutes. Interviewer was very friendly and walked me through a couple of steps where I got stuck. One logical question and one statistical question was asked.

Interview

I received a first round interview through phone call, and I was on the phone with a trader. I was asked 2 probability and statistics questions, and overall had a lot of fun!

Interview

They asked a range of questions about probability, chance, and light statistics. You do have a time limit to answer and it can be very nerve-wrecking. You should appear as confident as possible. I was asked some business questions as well - scenarios

Interview

Got a phone screen. Was asked a couple easy questions about basic probability/statistics. I got through those really quick. Then got a difficult question I spent a lot of time on.
