I applied online. The process took 2 months. I interviewed at Jane Street (New York, NY) in Oct 2023
Interview
The first round interview was a technical interview. The interview consisted of two main probability questions, in specific dice games. After finishing the questions, the interviewer let me ask questions about the company.

Question 1
The interview question is about a dice game. There are variations of the game, and we need to compare their expected values and variances, and choose which one should we participate in.
Went through 3 rounds of interview, all of which were focused on math. they started with basic questions and built up to harder ones. Also some behavioral questioins at the start of each round
Applied online and passed the resume screen, got invited to a first round, didn't pass, was my first time interviewing for quant and nerves made me answer not quite at the best of my ability

Question 1
Mainly I failied since I tried to give them a strict answer to one of the problems(which was impossible to calculate in this time) and the wanted to hear some intuitive approach which leads to approximately correct answer.
