Capital One interview questions

I had a recruiter screen followed by a hiring manager interview. After the hiring manager interview, they made me take a ridiculous personality test, and the recruiter said I had failed with no explanation or insight into what they were screening for and why I specifically failed. Overall this was a pretty bad process with limited insight or accountability from HR.

I applied in February. Took an online technical assessment that comprised of four leetcode like problems. I wasn't able to finish them all, but somehow managed to pass. Some Capital One recruiter reached out to me, but for a different position. She told me that I passed the test. Okay that's nice, but what's next? Four months later and now in June, suddenly I have a Capitol One recruiter reach out to me about the position I applied to. She wants to schedule a Power Day interview with me. The Power Day interview consists of a technical coding challenge, system design, behavioral, and a case study, four hours in total. Recruiter arranged a call with me to discuss what I should do to prepare; it's like you're basically studying for a final exam except you haven't spent a semester learning the material and need to spend a or two trying to study or learn system design especially if you have never done it like me. On the actual Power Day, two of the interviewers seem nice and were more conversational. The other two technical interviewers feel like they were making jabs at my technical ability so I knew then that I wouldn't be getting the job. Nevertheless, a few days after the interview. My recruiter reached out and asked me when was a good time to talk about the results. She called me and told me I did not pass and if I wanted to, I could try again in six months for other Capital One jobs. Okay? Why didn't you just email this rejection notice instead of needing to tell about this through a call? Capital One thinks they're a FAANG company with the way they're conducting their interviews, but the salary you can potentially earn is nowhere near the FAANG companies.
