I applied online. The process took 1 week. I interviewed at Capital One
Interview
Applied Online. Initial Phone interview had basic math questions related to profit-loss, breakeven and weighted averages. Second round in person interview..2 case studies and 2 behavior rounds.
First Case was on credit cards, the common on found on glassdoor.
I blew up the second case, so will try to re-create as much as possible. Cap One wants to run a campaign for 4 months, what will be profit before and after. How can you determine if the profit is because of the campaign. Internal team came up with some numbers : 8$ profit per person before 4 months and 9 $ after, and my original calculations were 10$ profit before and 12$ after..so basically calculate relative profit.. basic concept was incremental profit..so read up on that
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
Interview questions [1]
Question 1
In one of the rounds I was a given a question related to debit/credit card
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.
