Capital One Senior Software Engineer interview questions

Started with an online assessment, recruiter call, hiring manager, and then power day. The questions and format are the same as the other reviews on here. My interviewer during my system design interview had a heavy accent and I had a hard time understanding them, which led to frustrations on both ends. My interviewer during my case study was clearly focusing on something else while I was working on it. He also provided zero feedback during, which felt off-putting.

There was a power day with four interviews: two technicals, one behavior, one case interview. I did well in them, but I didn't receive any feedback. It's been almost three weeks since I completed all the interviews, and there's been no update from Cap1. The process seems unresponsive. They ghosted me.
