Jane Street Quantitative Trader interview experience

The whole conversation felt friendly and pretty low-pressure, and most of what I was asked was probability. The interviewers pushed me to explain my reasoning clearly, step by step, and they seemed genuinely interested in how I thought rather than just whether I could produce the final answer instantly.

It ended at the first stage for me, so I didn’t make it to later rounds. Even though I didn’t progress, the experience itself was positive because the atmosphere stayed supportive and it felt like they were evaluating both my technical thinking and my communication.
