Ho sostenuto un colloquio presso Jane Street (Londra, Inghilterra)
Colloquio
Jane Street’s interview process is fast-paced, multi-round (But if you have a deadline they will react accordingly) , and deeply quantitative: mental math, probability puzzles, game theory..., and conversational talk just before you start doing the problems
Domande di colloquio [1]
Domanda 1
Some basic probability questions (more like brainteasers) involving expected values and markov chains. You should brush up on the greenbook and be comfortable with n-sided dice and strategies involving dice in general.

Colloquio
Interviewed for two rounds. I passed the first round last year so was able to continue immediately with the second this year. Probability/game theory questions. The interviewers are friendly and helpful.

Domanda 1
If you roll a dice and receive that amount in dollars but have the option of rerolling up to two times, how much would you like to pay to play this game?
I went through the first 2 rounds, they were mostly technical. Mostly dice game problems and basic-medium probability questions, nothing on market making. Heavy emphasis on expected value. Harder to get the interview than the interview itself.

Domanda 1
Rolling a 100-sided die, best rule to stop, $1 to play again.
