Very standard interview process, first round: phone screen with HR, then a phone case interview - pretty standard case, you can find case interview example on COF website; then I was invited to on campus interview - two cases and two behavioral - 4 interviews in the morning; then candidate who made it to the "final", will had a conversation - a mix of case and behavioral with a VP+ in the afternoon.
I applied through an employee referral. The process took 2 weeks. I interviewed at Capital One in Dec 2019
Interview
The whole interview process takes only 2 weeks.
After HR's screening, I was given one case study with profitability and breakeven calculations. The interview takes about 45 minutes and it is led by the interviewer.
I applied online. I interviewed at Capital One (McLean, VA) in Feb 2020
Interview
First HR screen, then one Phone Case, on-site Powerday with two cases one product interview. the on site interview will have cases with behavior questions. you may prepare the case by reviewing MBA case study book. the quantative calculation is fine, but the logic behind needs to be clear.
