I applied through a recruiter. The process took 5 weeks. I interviewed at Capital One (Nottingham, England) in Nov 2018
Interview
There was a screening code test on HackerRank, which failed to work multiple times, but was progressed onto next stage anyway. so cant say much about that, from what i could see looked like basic array manipulation
Phone interview with hiring manager, just general questions about experience and more detail about the job and job fit.
Then face to face interview which contained 4 parts
- Job fit
- White board system design
- behavioral
- paired programming
All of which were in a somewhat relaxed atmosphere.
Feedback I received was interesting, apparently they felt I was somewhat "bluffing" which was slightly offensive, not sure how this was founded as any question they asked to dig deeper was answered. They were critical having to probe for more information despite following the suggested STAR method and not knowing what was on their structured answer sheet.
Felt like hacker rank failing to work, worked against me as the exposure they had to my development skills was limited to a 1 hour of paired programming, I had offered up code from some published apps I had written which would have shown 100's/1000's of hours of my coding effort instead, but they didn't really seem interested which I found weird.
In the end there was a stronger candidate, so although I had "passed the interviews" the position was taken.
Everyone I met through the day was super nice and welcoming, a somewhat enjoyable day really just a shame they felt like I was bluffing.
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.
