Jane Street Quantitative Analyst interview: probability rounds and nerves

After applying online, I had a resume screen and a first technical round. It was my first quant interview, and I was nervous enough that I did not answer as smoothly as I wanted. I did not move past that round.

I later entered through a program that sent me directly to interviews. There were two 45-minute Zoom technical rounds. The first was clearly easier than the second, and the interviewers were considerate about whether I could recover when I hesitated. The questions centered on probability. I could usually reach the right answer, but pacing and confidence mattered, and I again did not progress or receive an offer.

Location: Sydney. Overall feedback: positive. Offer status: no offer.
