Ho sostenuto un colloquio presso Jane Street (New York, NY)
Colloquio
Very difficult, probability, brainteasers, game theory questions. Interviewer helps walk you through the problem but gives few hints. Set up of questions is sometimes very complex so make sure you understand the setup before starting to solve the problem.

Domanda 1
Question about dice rolls and the probability distribution of sum. Play a game with the interviewer and decide the optimal choice
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

Colloquio
I was qualified for the first round of the interview proccess. I was asked about the reasons why i want to become a Quant and why i applied in Jane street for this role. After I was asked two probability questions. The interviewer was ok but at some moments I wasn't sure if she was following my thoughts

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.
