I applied through an employee referral. I interviewed at Capital One
Interview
The first round was an on-campus behavioral interview which consisted of four questions. After the first round was the final on-site interview which included a behavioral, case, and job-fit (technical) interview one hour each.
The interviews were not too stressful and they asked very simple questions for the technical interview. I'm not entirely sure what they're looking for in a candidate since there's no way that their technical interview can screen out a lot of people. I had no idea if I made a mistake on the technical, case, or behavioral interviews, but it was probably behavioral since that's pretty subjective (if you fit the culture or if they want to work with you).
From the on-site interview to the tour it was pretty obvious that Capital One takes care of their employees; they give you snacks and a one hour break randomly scheduled in your onsite interviews.
Interview questions [1]
Question 1
Given a string, return the first NON-repeating character that occurs in the string.
EX: "adzbdcab" returns 'z'.
4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.
