On Final round, there are live business cases led by an interviewer. I was given a business problem (e.g., increasing revenue for a retail bank product), and I had to walk through the problem structure, make assumptions, perform quick math, and propose recommendations. The interviewer provided data along the way.
Tip: Capital One's cases are not like consulting (McKinsey-style) but more conversational and practical, often with data interpretation and business sense.

Interview
1) CodeSignal proctored test. Tests analytical prowess and SQL. Time is tight, with increasingly difficult questions. You have to pass to move on.
2) Data Challenge. Python coding challenge to answer 5 questions. You need to merge/ clean your dataset and make a recommendation. You present it during power day.
3) Powerday. 4 interviews back to back. 2 case interviews, 1 behavioral interview, 1 data challenge interview.
Powerday 4 rounds back to back. One data challenge presentation , two cases and one behavior round. Overall easy and it was a nice experience. Interviewers responded the follow up questions detailedly.
