Questions d'entretien chez Jane Street

Phone interview for two rounds then rejected. Asked Probability questions and Maths teasers. Very difficult but the overall experience is encouraging. Would love to apply to them again. Many options and freedom in choosing offices and teams.

interview process involves multiple rounds of phone interviews with questions centered around probability. after phone interviews there is a final assessment day on site. The questions become progressively more difficult as the rounds progress and it is definitely worth studying for them.

Lots of mental probability and testing of your sense of how probabilities move around when factors are changing rapidly. Exact answers are not always expected but estimations should be pretty accurate.

Haven't done any interviews yet, but this website forces you to fill a review out to continue using it. The process has several rounds, I think a few consist of probability questions, and the final round is several hours long and held in person.

Preparing for the second round. The first round is a 30min phone interview. Very basic probability questions. Phone connections on their side was not very good, so I asked the interviewer many times to repeat what he just said. The interviewer is a quant trader himself. He was very nice.

I applied online and just a week later I received an automated email from the "Recruitment team" saying exactly this "We are unable to find a good match for your skills and credentials at this time". When I read this reply it immediately became crystal clear that my CV had not even been read let alone consider it. My CV matched perfectly well the requirements of the job advertised, not only the mandatory ones but also the desirable ones in addition to my credentials that also matched their requirements so I was not sure what they were not able to match there so based on my experience, my conclusion was that either an incompetent member of the recruitment team had dealt with my application or their recruitment process lacks transparency or most likely, a combination of both. If they had other candidates that had more experience which of course can happen, they should reply and say that they have identified other candidates more experienced instead of saying an automated reply that do not conform with reality like it is my case. Although, this experience put me off completely and I lost interest in the company, I felt strong to reply to their automated response and their reply was even more disappointing not only they did not address my questions but also said that providing feedback was not part of their process which confirms the lack of transparency. I never asked for feedback in my email, all I said is that if they have other candidates that are more experienced then they should say so in their reply instead of saying that they cannot find a good match for my skills and experience when my CV matched perfectly the requirements of the job, basically, be honest. Based on this experience, it was good that my application did not advanced any further as If this is how they deal with candidates at this point I prefer not to imagine what will be like once you are in.

I think the interview is hard for someone with less technical background. Even though they said that candidates with different disciplines are welcome, I do not think it is the case.
