Capital One interview questions

First round on campus. Basic Capital One type case study on a gym at the Capital One office and how much money should be charged to use it. Final Round at Capital One's office. Three interviews, 1 behavioral, 2 cases. The cases were similar to the first round interview case question.

I saw the posting on my University's Career site, I then sent a follow up email to the recruiter. She then let me know in that she wanted to have a phone case style interview. (about a week) I had the phone case style interview. The interviewer was very nice and reassuring over the phone. He asked me about paperless banking. First he asked how we would get more customers to join paperless billing. We then talked about incentives. If we send out 100,000 emails. two plans 1. 50,000 20% response rate and $4 credit and 2. 50,000 30% $10 credit. we save lifetime $12 on people the switch how much do we make. I was then asked to calculate the break even response rate for the $10 credit email.
