Very friendly process. I had practically no finance experience and Piper was my first finance interview of the banking recruiting process. I learned a lot in their process, actually, since each interviewer asked similar questions to his or her predecessor. The advantage was that if I screwed up in one interview, I would know the right answer in the next. They're completely okay with you making mistakes so long as you're open to learning. Personality mattered a ton -- I really, really liked those folks.
