Capital One Senior Software Engineer interview questions

Besides of proctored CodeSignal online assessment, interview consists of the most important thing called "The Power Day". It is typically four 1-hour interviews in a row with 30 mins break. For me it was coding, system design, case study and behavioral. I finished coding and system design in 55 minutes. Case study in ~25 mins and behavioral in ~15 minutes. Even though those inteviews were ok and I completed all the tasks (as I assume), I've been ghosted by a recruiter without any feedback after the power day. In a week I got the basic workday rejection letter "Unfortunately we proceed with another candidates etc". No feedback was provided, no reason why I was rejected. Another recruiter contacted me next day to assign one more interview, he told me my background and experience is really fit to theirs role, but "unfortunately, you can't interview after rejection in a 6 months, even for a different position". I would say that interview process is generally neutral, but recruitment process is a mess. If you are little bit lucky probably you will pass it all. Btw only one of the interviewer on the power day was respectful in any way.
