I applied online. The process took 2 weeks. I interviewed at Capital One (Plano, TX) in Apr 2019
Interview
3-4 rounds. Mostly technical. Expect some white boarding and typical STAR questions. I had two phone calls, then an onsite. But this seems to vary from team to team. Example question below
Interview questions [1]
Question 1
Given a string and a substring of that string, find out how many times the substring repeats in the parent string
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.

Question 1
Merge overlapping intervals from a list of time ranges
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.
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
