J'ai postulé en ligne. J'ai passé un entretien chez Jane Street
Entretien
Applying for winter internship. Had one interview thus far over phone, spoke with Tim who was nice and patient when I took a while to answer a question. Was somewhat friendly but mainly was professional and to the point. Interview questions were mental math and logic, received a second interview for later.
Questions d'entretien [1]
Question 1
There are infinite cards numbered 1-5. You construct a deck. Someone guesses a value and draws a card. If they guessed correctly, they get the value. What composition of the deck minimizes their expected value?

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
