I started off as a Financial Analyst Asc. I only interviewed with the hiring manager although many people have told me that they interviewed with more than one person. The interview process was pretty simple and straight forward. The manager mainly asked me about my experience, previous workplaces, etc. If I could recommend something, it would be that try to be more personable with the interviewer(s). Remember that they look for people with soft skills too. Because of the method of finance that they use, most people need training on that anyway. So your former financial analyst skills may not matter all that much.
