Capital One interview questions

Had an on campus case study interview. Got a call back a few days later and was flown out to Virginia for more interviews. The day consisted of 3 interviews, 2 case study interviews and 1 behavioral/job fit interview.

I was e-mailed to let me know I had made it through to the first round of interviews and that it would be a 30 minute case interview. The date of the case interview I received a call right on time and was asked a few simple breakeven and profit calculation questions. I know I answered them all correctly, however I did stumble while I was verbally walking through my calculation; I had to backtrack and I think that's what ultimately killed me. You need to be able to walk through the problem casually and easily, but without hesitation. I was not invited for the final round and I can't say I was too surprised.
