Interview
Phone interview was called after being asked for a specific date that i was free, was told the interview would last 15-30 mins and no pen or paper. Was told i could ask questions after the interviewer was patient and willing to hint me in the right direction

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.
