It was a pretty grueling interview process. I was a there from 8am to 5pm in a conference room with different interviewers coming in every hour. The only breaks I had were between interviews if one ended early or the next person was late. An admin brought me lunch but there was no break to eat. Naturally the toughest interviewer was at the end, grilling me when I was exhausted and hungry. I suppose that may have been a tactic to see how I handle stress.
I was offered the job but for a regulatory associate, not Sr. Associate as I had applied for. I considered not taking it because the interview process gave a bad impression.
