I applied online. The process took 3 weeks. I interviewed at Capital One (New York, NY) in Apr 2022
Interview
Applied online for software engineer position.
Very nice interviewing process, the recruiter explained every steps and everything I need to know.
(1) Phone interview (15mins)
Talked about my background and experience, nothing technical.
(2) Online assessment (2hrs)
4 leetcode type of questions, easy-medium-medium-hard, score > 70% should be able to pass, so don't worry if you don't have enough time to finish all questions
(3) Power day (4.5hrs)
The interviewers have really thick accent, can barely understand what they said and they are not willing to repeat the questions. Technical issue on codesignal.
(3a) Code - leetcode type of question, write a function about prime number
(3b) Design - high availability and scalable system, infrastructure / system design / database design on a given topic, UI / APIs / testing methods / resilience / db schema / etc, show your details -- as much as possible
(3c) Case - (1) pros and cons on a given business case (2) given a piece of code and data, explain the logic and improvement and expected output by given input
(3d) Behavioral - 3 questions on "... tell me about a time ...", be details -- as much as possible
(4) Catch up (15mins)
After 2 days, I received an email to schedule for a follow up call. The recruiter called and said I was rejected. Really don't think they should do this. Bad experience.
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.
