I applied online. I interviewed at Capital One (Chicago, IL) in Oct 2020
Interview
I applied online through Workday, and I received an invite to interview within a week on their "Power Day" (I think it just means that it's their final interview, I'm not really sure). The one final interview consisted of 3 interviews in a row: technical, behavioral, and case. Case is definitely the hardest one (because it requires background business and company knowledge), but I think they understand that many SWE interns never have had exposure to this so they must've went easy on me.
Interview questions [1]
Question 1
Technical: Two leetcode easys (you have to implement these) and one leetcode medium where you just explain what data structure(s) you would use to solve this.
Behavioral: Explaining technical thing to non-technical person, proudest project, one other I forgot. Generally really easy.
Case: Required a lot of background business knowledge, but at the end you had to reduce dead code in some if statements.
Power day (technical, behavioral, case study). Online assessment beforehand using code signal. Leetcode medium level questions for all (maybe 1 easy in the OA). Prepare for object oriented programming as well.
1 tech with easy leetcodes (4-5 subparts), 3 behavioral questions, and 1 case with information about understanding a C1 problem and applying the following provided information to create a solution.
