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).
