I attended a pre-college visit offered by the company and they maintained communication with all of the students who visited. I replied to one of their emails and they offered me an interview for a trading position. The interview lasted 20 minutes and the interviewer was very nice. All of the questions involved probability questions that were to be computed mentally.

Very smooth. Around 30mins first round 1hr for the second round. First round consisted of easier probability based questions. Second round was similar but harder and longer questions. The interview process if approached in a calm composed manner should be easier to analyse
multiple phone interviews and a full-day Zoom interview. Interviews got longer and longer over time, but every person was very kind and helpful with hints when I got stuck. The questions get harder as the rounds progress and generally don't have a closed form answer in the later rounds
