Capital One Project Manager interview questions

I applied online and the process took two weeks. I interviewed with HR then did the mini case. Honestly, I was really nervous about it because the reviews on here about that are so negative. I had a good experince with the interviewer. It was six parts and within each part a couple questions. I didnt think it was hard in-fact I thought I would move forward but I did not. I was really surprised to get an automated rejection email, as I thought I did fine and would move forward, but especially because I had been in communication with the recruiter prior. I will say that the recruiter did a poor job explaining the mini case but I felt prepared nonetheless. Ive never done this style of interview so I wonder if they wanted me to answer the qs differently. I wish I knew why they didnt move forward with me :( the next step woudlve been a power day. Ive read such negative things about power day on here.
