J'ai postulé en ligne. J'ai passé un entretien chez Jane Street en févr. 2022
Entretien
After applying they emailed back very quickly to set up an interview on the phone with one of their traders. It is a short interview for only about 30 minutes where they ask mainly probability questions about dice and cards.

Entretien
I had to do a problem as I applied (blotto) and I passed that first stage. Next stage was a phone interview, in which we first discussed a problem I was asked to do prior to the interview, and a new problem in probability.

Question 1
We first talked about the blotto problem. Then did a classic probability question, with Markov chains. Had to make realisation about each step being independent and then turn part of the question into a geometric sum. He led me through quite smoothly.
