The response after application was quick. I have received an online coding test 1,5hrs long. I think I did it well enough. Then I was asked for a phone interview with manager. After that there will be an on site interview.
Interview questions [1]
Question 1
One of the questions was about checking if numbers from 1 to n divide 3 or 5 or both. Accordingly you are expected to write a string instead of the number itself.
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.
