I applied through college or university. The process took 2 weeks. I interviewed at Capital One in Feb 2019
Interview
I submitted my application online and they got back to me via email within a month. They set up an in-person interview a week from sending me the email. The in-person interview includes 3 Interviews in one sitting, including a behavioral interview, a case interview, and a technical interview. The case interview was challenging but Capital One did offer all interviewees workshop and demo videos to help us study. Coding questions are fair. Need to know basic data structures.
Interview questions [1]
Question 1
Describe a situation you have to explain a technical concept to a non-technical person.
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.
