Interview with the recruiter
I was sent to their interview funnel through CodeSignal.
I declined their code signal assignment (Their funnel) There are some companies making a living out these interview processes (Codesignal, Triplebyte, Hackerrank, etc)
Hiring companies (including Capital One) just send you to their standardized test and make you go through their 'funnel' (you are just another unit in their whole statistic).
To me I don't think companies are not doing a a good job assessing your real skills for the specific job. For example, the job that I applied for had little to do with the sample test that I saw on codesignal.
Additionally, because companies like Google, and Microsoft were successful early on by hiring 'solve the algorithm' type of engineer there are a lot of other companies assume that doing a similar process will make them hire the right candidate and be successful like those companies.
Don't buy into that, make them do better.
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.
