I applied online. The process took 2 months. I interviewed at Capital One (Richmond, VA) in Jan 2022
Interview
The interview has 2 technical rounds and 1 loop.
First-round: Proctored Codesignal test which includes SQL + 14 data manipulation questions that can be answered as per your convenience (using excel or python).
Second - round: Data challenge ( airline dataset). You will be given 14 days to answer.
Final Loop- contains 4 rounds.
1- Technical involves Data challenge presentation and technical discussion
2- Case study One
3- Behavioral
4- Case study Two
More emphasis is put on the case studies than on the rest two rounds. Interviewers are good at giving positive impressions, so it wouldn't help you assess if your interview is going well. Even if you successfully answer your case studies, the chances are you might not be offered the position. I think they put more emphasis on how you present yourself, like maintaining your professionality even if they seemed friendly and do not get too comfortable.
Remember that the loop lasts 5 hrs long, so make sure that you are energetic.

Question 1
Airline dataset.
Case studies are already mentioned here.
Started with an OA, and then proceeded to data challenge, and afterwards it was Power Day which had 4 rounds of interview. 2 of them were more problem-solving, and one of them was walking through the data challenge

I applied through university. I interviewed at Capital One (Plano, TX)
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.
