I talked to Capital One at my college career fair, applied online, and got a final interview on campus. They were very fast throughout the whole process. The final interview had behavioral, case, and technical. During the technical interview, you're required to write code on paper, and if you get stuck the interviewer is pretty good about helping or leading you. They also had a design question. For the case interview, they just want to know how you think, and my interviewer was very relaxed, it felt like a sort of conversation rather than an interview. The behavioral just included some basic "tell me about a time when..." questions. They got back to me within two days. Overall was a very positive experience.
