I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in Apr 2024
Interview
Jane Street’s interview process for a quant research role is rigorous and intellectually demanding. Applicants typically face multiple phone screens, focusing on mathematics, probability, and logical reasoning. Successful candidates proceed to onsite interviews, featuring in-depth technical and problem-solving challenges, culminating in collaborative discussions and culture fit assessments for final consideration.
Interview questions [1]
Question 1
probability questions like “You’re given a biased coin with a known probability 𝑝 of landing heads. How would you determine the expected number of flips until it shows heads twice in a row?”
The process began with serveral online tests for maths and logic. They gave a personal interview to get to know the candidate better and evaluate fit for the company/role, then held a technical interview covering maths and logic problems.
Fun and filled with unexpected questions. The questions rely on fast thinking and fast calculations, and sometimes intuition because there is no sufficient time for me to work through the whole problem.
We started with a bit of small talk, followed by some probability questions. Ended with some basic algebra questions, Make sure to ask questions if you have any. Good experience, feels like the interviewer was trading.
