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.
