First-hand accounts from people who interviewed at Jane Street.
Summer Analyst
The whole interview was 2 math problems. It was a conversational problem-solving process. The first question is almost always a more calculational probability problem, and the second focuses more on game theory. There might not be a best answer - think heuristically to respond with at least something sensible.
- Mathematical problems, specifically probability and game theory.
Infrastructure Analyst
First, I dropped my resume on their website. Then there was an initial screen with an excel exercise. After that, I had a phone screen with someone on the team. They didn't ask any behavioral questions, but asked me to prepare some maths questions. The final round interview was in the office and lasted from 2-5 hours, with a 2 on 1 interview. The recruiting team was unbelievable, very efficient in scheduling interviews and letting me know the results quickly. The phone interview was pleasant and the interviewer was nice even though I didn't answer perfectly. The final round interviewers were interesting, though it wasn't the best final round experience I've had.
