For the information of future applicants:
The interview was non-technical and fairly casual. I come from a non-finance background (BS/MS in math) so he asked me "Why are you here?" once my motivations for entering the program were clear he said that I "made my case" and the conversation seemed to switch to chit-chat mode. I got the impression that once my motivations were established that I was deemed acceptable, and then he just wanted to give me information about the program. I left with the expectation that I would be accepted, but I can't be sure until the 31st!
