I applied online. The process took 1 week. I interviewed at Capital One (San Francisco, CA) in Sept 2023
Interview
Recruiter phone screen. Technical assessment on CodeSignal requires you to share your screen, microphone, and camera, verifies you pass the recording requirements and is pretty invasive. The assessment is 4 Leetcode medium questions for 70 minutes. The recruiter told me no one ever finishes the CodeSignal and the pass no pass doesn't have a pattern so is pretty arbitrary. I think you have to get at least 3 questions completely right. There are 10 visible and 10 hidden tests for each question, so you don't know which hidden tests you got wrong. I knew the second that CodeSignal was used with all these extra requirements that it would be a negative corporate environment or engineering culture or even worse.
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.
