Ho sostenuto un colloquio presso Jane Street (Londra, Inghilterra)
Colloquio
HackerRank typing challenge, basic probability. Video call with a Trader, lasting about 40'. Interviewer was nice, I think you are expected to get through the first interview without needing help until the very last question (I didn't).

Expected value of a game of coin tossing & strategy to optimise profit. 4 sub questions with scenarios becoming increasingly difficult. Very similar to Youtube mock interview question.
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

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.
