I applied through college or university. The process took 2 weeks. I interviewed at Capital One (Richmond, VA) in Sep 2015
Interview
First I interviewed on campus in Nashville, TN. Then I was invited to the main office in Richmond, VA. Everyone was friendly but it was one of my most intense interviews ever, of course besides google interview. The interview was divided into 3 sections. Technical, Case studies and behavioral.
The most excruciating was technical, I was given four programming problems to solve in 45 min. The first one was to implement binary search tree, the second was about linkedlist, the third was about implementing an algorithm to manage students resumes using java, and finally the fourth was sorting.
The interviewers were nice, but that is deceptive as it will make you feel like you are doing well when in the end they already know they are not giving you an offer.
I was contacted my my campus recruiter a week later and left a voice message saying I was not extended an offer with no explanation. I never got an official letter from them. Every attempt to speak with my recruiter afterwards were ignored.

Question 1
Implement binary search tree to return the rightmost child node
Reverse a linked List
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.

Question 1
Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
