Questions d'entretien chez Jane Street

went fast. the interviewer asked typical interview questions such as where you see yourself in five years and whatnot. not as scary as you would think. also asked me about projects that i have listed in my resume and also asked me about the skills that I have listed in my resume

Conversation about background + brain teasers + a lot of follow up questions. The interview is really intellectually stimulating and the problem-solving is very intense and gets harder with each round.

Did not get an interview with Jane Street. Was contacted to thank me for my interest and denied. My application was strong and yet I still did not make it past the first round

Technical combinatorial and probability questions first. Further in the process, from 3rd interview on, game theory. Most of it is thinking out loud with the interviewer to deduce possible answers.

it wasn't too bad, typical dice and card games. know easy game theory. I think you should be good, don't need to be genius. Additionally, the work environment wasn't too bad pretty prompt.

I reached a phone interview. I got a single, fairly non-leetcode question, but harder than most leetcode hard questions. Then three followups to it. I completed two, but could not complete the third one so I did not make it and did not get an invitation to the final. Kind and supportive interviewer.

They are all new questions from the previous and I did not prepare any of them and they are more difficult. The hr is very mean and has bad attidutde and i do not like her.

3 Rounds of telephone interviews focussed on probability and games. In particular, games involving coin flips were popular and having to come up with the optimal strategy for the game. They became progressively harder. I did not progress further than this.

First round: self-paced analysis using excel, simple write up. Second round: audio call, asking about your problem solving analysis. Much more difficult, could be asked anything, seemingly. They don’t expect a correct answer, just how you get to your answer.

One phone call maths interview (fairly basic maths problems) One video call interview about markets and trading One video call interview about building a trading platform (using pseudocode/flowchart to show how it would work)
