Summer Analyst

HR contacted me and set up a phone interview for two weeks in the future. I was informed the process included a phone interview and then superdays. The interview was scheduled for a half hour and went the full time. It was extremely focused on health-care as I got asked questions about certain sub-industries I really didn't know anything about. I also was asked what about my personality suits me to banking. I responded I like working on long-term projects. He asked why. I responded I thought it would be exciting to work on something for so long and then see it through to completion. He asked why that was exciting. I thought that was kind of BS but didn't know if he was just giving me a hard time. I feel like he wasn't in a particulary good mood. I was later informed by HR that I originally was supposed to have a different interviewer so I think this guy might have just been pissed that he had to interview me to begin with.
