I applied through a recruiter. The process took 2 weeks. I interviewed at Capital One (New York, NY) in Mar 2018
Interview
A recruiter reached out to me on LinkedIn and sent me a coding evaluation that took about 4 hours (building an app).
The second interview was pretty unpleasant. It consisted of a phone interview with myself and three engineers but it really felt like they were teaming up and attempting to bully me? By bully I mean that they would continuously cut me off and have side conversation, but I didn't feel I was in a place to ask them to stop.
Finally, I was invited to an event Cap One was hosting in NYC, which was fun and I got to meet a lot of cool people.
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
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.
