Colloquio
I went through a first round phone interview at JS. This was my first attempt at a quantitative trading interview so (not surprisingly) I failed it.
I set up the interview with one of their HR people. On the day that the interview was supposed to occur nobody called in. When I tried to check in with the HR person I learned that she had left the company! Scrambling, I contacted someone else, who set up an interview with someone later in the same day. During the interview itself I was constantly distracted by lunch chatter that was happening on the other end of the line. It would have been nice if the interviewer took the call in a quieter place. Maybe that's just how trading works and is an indication that I'm not fit to be a trader, which wouldn't be the worst thing ever.

Colloquio
The interviewer was very informative. The questions appeared basic initially, but they required deeper reasoning, strong fundamental knowledge, and careful problem-solving instead of simple, straightforward answers throughout the interview process.
The process was structured and intellectually challenging. It typically involves an initial recruiter screen, followed by probability, mental math, expected value, and game-style problem-solving interviews. Interviewers focus more on reasoning, communication, and adapting to feedback than memorized answers.

Domanda 1
You have two opaque boxes in front of you. At each turn, you may choose one of two actions:
Place: put one coin into one of the two boxes, chosen uniformly at random.
Take: choose one of the two boxes uniformly at random, take all the coins inside, and empty that box.
You play for exactly 100 turns. Your goal is to maximize the expected number of coins you collect.
What is your optimal strategy?

Several phone calls to go to the final round. The phone calls consists of mathematical, probabilistic brain teasers which was not that hard for a mathematics major. Final round was to harsh for me, strong mentality is required
