I applied through an employee referral. The process took 3 months. I interviewed at Capital One (San Francisco, CA) in Aug 2017
Interview
1. Phone screen with engineer
2. Phone screen with engineer manager
3. Remote technical with engineer manager (video chat)
4. On-site half-day interview. 60% technical questions / 40% behavior questions.
They were a little disorganized because I got an automated email from their recruiting system that the position had been closed. I thought it was a rejection letter and didn't check back with them for a month. Then they told me I just needed to reapply.

Question 1
Write a function to return the nth number in the fibonacci sequence.
Scheduled a call with recruiter. Recruiter didnt show up for the screening call and cancelled it 5 mins after the scheduled time. Dropped a follow up email and got no response. After a week, I got an email from the recruiter stating I am selected for the next round i.e Assessment. Sent me an email with the assessment description but no link. When I sent a follow up email asking for the link, I got ghosted again. It was a bad experience. Felt like she is toying with me. Why ghost an applicant repetitively? Unprofessional recruiter who doesn't respect an applicant's time or efforts!
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.
