BMO US Personal Banker interview questions

Had a phone interview through HR, in which I assume they want to know what the branch managers are looking for. Then I was called in for a branch interview in which consisted of two branch managers which they both asked questions. Two were there because they were both trying to see which branch I would fit.

attended a job fair at BMO's new building in Naperville, IL off of I-88. After talking with several hiring managers in various departments, I finally talked to someone in Collections who wanted me to schedule a formal interview for the position of Loan Collector. I met with someone from HR who scheduled me to meet with the hiring managers in the office in Rolling Meadows. I interviewed with 2 managers who were both asking me questions. Their questions were fine--nothing you wouldn't expect in an interview. Soon, we came to "So what questions do you have for us?" That's when I started to doubt that this was a good fit for me. I asked them "What is the culture like? Is it a fun place to work?" The answer I got was not convincing. It was almost like they were trying too hard like, "It's REALLY fun. No, I swear. People LOVE it here." I'm not buying it. When I asked if I could spend a few moments out on the sales floor to see what the work environment is like, they politely declined, saying that my request wouldn't be possible. Well now I'm definitely uncomfortable. It's like they didn't want me to know what I'd be doing. Sorry, I'm not going to leave my current full-time job unless I know what I'm getting myself into.
