Ho presentato la mia candidatura online. La procedura ha richiesto 3 mesi. Ho sostenuto un colloquio presso Jane Street nel mese di nov 2024
Colloquio
There two to three phone interviews before you get flown out for the final round in office. The questions are mostly probability games with a ton of follow ups. I would say they are basic math competition difficulty.

You have a drawer of infinite socks in a 1:1 ratio, what is the expected number of draws to get a pair?

The interview was very disappointing. This was my 3rd round with the firm, the interviewer barely cared about my solutoin, was yawning, disinterested for some reason. So, yeah it was a pretty bad experience and no!! I was not doing stupid stuff in the interview it was just a bad day i believe. The question that they asked was about 10 cards on a deck and by the end they were able to make it a multiplayer game where you had to think of a winning strategy with x red and 10-x blue cards.

They asked mostly probability and game theory questions. On-site consisted of a lot of betting games. Very collaborative experience when working on through questions. Overall I enjoyed the the interview experience.

First question was on dice rolling, you get one dollar if your roll is higher than your opponent then you win nothing otherwise.

For side bets, you can do on next card being red/black or higher/lower than 5.5 for 1:1 payout. (you need to figure out how to use this for arb)
