I applied through college or university. I interviewed at Capital One (Richmond, VA) in Oct 2015
Interview
I submitted my resume at a career fair, and then I got contacted to arrange for a day to fly me out to do an interview. They gave me a packet before hand about what to expect for the interview day (1 case, 1 behavorial/job fit, and 1 technical). The case interview was hard for me because I didnt understand what was given, and had to be lead throught the case. The behavorial is conversational, but they ask you like 3 big questions and jot down notes. The technical interview was about 3 problems, 1 design, and 2 other problems focused on using data structures. The whole day was very structured, and everything is well provided for you (hotel, lunch, reimbursement).
Interview questions [1]
Question 1
What was the most interesting project you worked on?
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.
