Interview questions [1]
Question 1
On power day, 2 case study rounds where the interviewer will provide case details and ask series of questions about the problem and data (give accurate answers and reasoning for your answer). In Data challenge round you have to explain the process and idea behind how you solved the challenge, then you will have series of questions based on your approach and explanation (e.g. why PCA ?, difference in weights obtained in manual and PCA?). Last is behavioral round.
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 college or 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.
