Met them on campus and applied online. I was contacted over email asking if I could come down to the Richmond location from Maryland. The follow up email contained a lot of prep material and details about the day. Capital One put me in a hotel and paid for my expenses for the whole trip. After arriving at the campus, we were split into groups of ~4 and taken on a tour by current employees. Thiis part was informal and my guide was very easy going and answered a lot of our questions about the work environment and how the rotations work. The formal part of the interview had 3 parts, behavioral (pretty standard), technical, and case. The technical part was a few coding questions on the whiteboard. While not terribly difficult, it is hard to think of all the different input cases so make sure to consider all possibilities when coding. The case interview for the technical position was not like the prep (business) video they sent. It was basically a coding problem in a business setting. The coding part was pretty easy but for this part they care more about your problem solving and analytical skills.
