I applied through a recruiter. I interviewed at Capital One in Sep 2014
Interview
I was interviewing for data scientist position at capital one labs (they started this project a couple years ago, based in NY, DC, SF). Initial chat with recruiter followed by a small online test (easy), a data mining coding challenge on a larger dataset (harder), 3 technical screen, 2 behavior, 2 job fit, 2 case interviews.
A couple of the interviewers told me they were still exploring the interview process for labs so... it seemed to me they currently threw a bunch of technical interview process on top of what they do with the business analysts. Recruiter is very nice and have good tech background.
The Richmond campus is very nice; new HQ at Tysons Corner looks impressive; lab try to imitate the startup environment, on the more relaxed side. (I went on-site to Richmond campus and DC lab, stayed one night at a hotel by the HQ).

Question 1
My favorite part is the coding challenge -- the right amount of richness in data & a peek at their credit card business... The process itself is grueling, way too long! They really should consider introducing some team-based match into the process.
I applied through college or university. The process took 2 weeks. I interviewed at Capital One (Toronto, ON) in Nov 2013
Interview
I applied to the position through on-campus recruiting at my university. They invited me to take several online tests (verbal, math and personality tests) which took about 2 hours in total. Afterwards, they invited me to interview for the position on campus. It was a 30min case interview and a 30min behavioural interview. The people were super friendly. I remember making a mistake during the case interview, but realising it and fixing it. HR called the next day to tell me that I made it to the final rounds, which was accompanied by a dinner the night before. We got to see their campus, which is really nice for a banking/financial industry company. We got to talk to people who are in similar roles at the company during the dinner. Next day, the final founds were 2 60min cases and 1 60min behavioural interviews. HR called the following day to give me an offer.

Question 1
Business cases are typically 30min long. I've never personally had any problems with doing cases, but these ones felt very intense because they were longer and involved more analytical skills. I barely finished the first case, with great difficulties. The interviewers were all very patient and nice.
