I applied online. I interviewed at Capital One (McLean, VA) in Sep 2020
Interview
Three round process behavioral, case, technical. Each round lasts about 45 minutes. Behavioral is pretty standard. Case you may receive code and asked how to make it better. Technical are pretty standard problems that you can find on leetcode. The average difficulty is around easy to medium I dont think you will see any hard level questions.
HR phone screen, a hackerrank take-home, followed by a four-hour back-to-back virtual onsite (one technical, one case, one behavioral and one system design). The behavioral and the case questions are the same as the ones in other glassdoor reviews. The technical is a leetcode easy. The system design is the hardest but the interviewer was kind enough to allow any approach (front-end to back-end or vice versa, OOD, high-level, UI design, etc).
