I applied through college or university. The process took 2 weeks. I interviewed at Capital One (Plano, TX) in Oct 2014
Interview
3, 1-hour interviews, behavioral, business case analysis, and technical. The interview was very smooth, The technical interview asked me questions mostly about basic data structures and how to use them for simple tasks effectively. The behavioral interview asked me about how I had solved problems in the past in different ways, structured mostly in a "tell about a time when..." sort of way. The business case was more confusing, the interviewer expects you to ask questions to reveal the next part of the interview but they dont help you very much, and if the interviewer hasnt explained the problem clearly then you are stuck.

Question 1
What is the difference between an object and a class?
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.
