Started with a quick 30 minute phone screening. I was asked a few behavioral questions, and was given a short case interview. A couple of weeks later, I was flown out by Capital One to Plano, Texas. There, I was given two hour-long case interviews, and one hour-long product interview. The Case interviews were a little tricky, and more mathematically oriented. The product interview was a straight forward discussion of a simple product that the interviewer chooses, and then a product that you get to choose.
