The hiring process was exactly as described by Capital One and other reviews in Glassdoor. They first reached out after finding my information on Linkedin. A recruiter called me and touched on all the basics - here's a general idea of the position, a little back/forth on my background, what I did, etc. to assess a potential fit. That followed with a current salary question and then ended by saying they would follow up - check my email.
I then spoke for about 30 minutes with the hiring manager on the phone - no video call. This was what you would consider a typical phone interview. Hiring manager was positive on our call - so HR put me through a battery of tests which took about 4hrs on a Saturday morning for me to complete. There was an English and math "test" as well as a profile-type test. After completing those tests, I received a call stating I would be invited for an in-person interview.
I interviewed with 3 people for about 30-45 minutes each at Capital One. From the moment I stepped into the building, they are clearly set up to interview people. There was a separate interview section of the building complete with HR offices, break rooms, "greeter", etc. They did it right. Well done!
