Standard interview: spoke with recruiter who then passed me off to another individual who was in the same position I was applying for. He was very uninterested and asked behavioral questions. After he asked me the probability question, I answered wrong. He blew me off and asked if I had any questions for him.

3 interviews total. Pros -All interviewers very nice and intelligent. Asked more soft skill / fit questions than technical skills - team seemed to be very close knit - fast moving / a lot of responsibility - small finance group(10 - 15 ppl) for multi billion dollar company Cons - a bit unprofessional, scattered process. The interviewer missed my email twice and failed to notify me beforehand both times
