Had a friend refer me in late August. Got a response exactly a month later asking to bring me in for a final onsite interview at their Richmond campus. Capital One does all of their final interviews onsite. They fed us a nice lunch, gave us a tour of the campus and then began interviews. Interviews consisted of 3 rounds of 45 min interviews. The three rounds are Case, Behavioral, Technical. Overall I found the interviews very easy. All of my interviewers were very helpful and I had a lot of left over time after completing my questions and was able to ask a lot of questions about the company.

Online Assessment -> Power Day Interview. Power Day was a total of 4 hrs, three one-hour interviews with a one hr break in between. Included Technical (coding from scratch), Behavioral, and Technical Case (answering questions and fixing code).
