I applied online. The process took 4 weeks. I interviewed at Capital One in Oct 2021
Interview
Applied directly on their site, and received a phone interview invite within a week or so.
Phone interview was around 30 mins and covered overview of the company and asked some basic questions like 'Why do you want to work here'?
Received an email with a link to the Code Signal. Took it a few days later and passed by solving 3/4 of the questions.
Heard back within a day or two with results and schedule the onsite final interview.
Onsite final interview had 4 rounds consisting of behavioral, case study, DS/Algo, and systems design. Heard back the next day with results.
Interview questions [1]
Question 1
Behavioral: prep a few stories and answer using the STAR method
DS/Algo: leetcode easy/mediums
System Design: Grokking System Design or comparable materials
Case Study: Can't really prep for this round
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.
