I applied through a recruiter. I interviewed at Capital One in Sep 2020
Interview
1st round wasn't bad, just a simple case over Zoom.
2nd round had 3 interviews with a break in between. Cases were a lot harder with more calculations. The interviews included a product review (talk about an app you use and how you would improve it) and also designing a new water bottle.
Interview questions [1]
Question 1
When have you gone above and beyond for a team member?
Not too bad, final round interview had 3 interviewers. the product one was more informal just wanting to know your thinking process and the others had a good amount of math that wasn't too hard.
One preliminary case study in the first round followed by three case studies three to four weeks later. The first round case was exceptionally easy, but I screwed up the second one on the super day over zoom.
