Capital One interview questions

It was just a case interview, calculator provided, and it wasn't a difficult question. No behavioral question asked.

I applied for the teller position of the company's website. I was contacted later by a HR rep who scheduled a phone interview. After the phone screen, I was contacted by them again stating that I should go to the Branch to meet with the Branch Manager. I had an interview on the premises - which lasted about 45 minutes. I received an offer two hours later - which to me was very surprising because I thought I bombed the interview.
