Capital One Senoir Software Engineer interview questions

Got a call from the recruiter then had to take a CodeSignal assessment the difficulty was medium. When I passed the interview they invited me for a power day. Power day was intense and very tiring starting with Systems Design (Banking App), Coding Round (OOD), Case Scenario (Budget reviewing on Testing), then a behavioral round. The case scenario was a bit tough and the behavioral round was total nonsense. Even after answering questions, the interviewer asked me if I would like to add more details (again and again). The very next day I got a call from the recruiter where he highlighted that I did good on the technical but not well on the behavioral and behavioral is as important as technical. Power day is very exhausting. I was very disappointed.
