I applied through college or university. The process took 1+ week. I interviewed at Capital One (Atlanta, GA) in Feb 2015
Interview
There was a behavioral, Technical and Case Interview. Each interview lasted approximately 45 minutes. The interviewers were all very personable and helped me reason towards good answers. Everyone was very nice and a pleasure to talk to. Overall, I enjoyed this interview despite it's length of 3 hours total. The interviewers were understanding and it was easy to get my point across and have general discussion with them.
Interview questions [1]
Question 1
You have a tree of accounts. Write a program to sum any sub-account passed in.
Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.
Interview questions [3]
Question 1
Merge overlapping intervals from a list of time ranges
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
