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
Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.
Interview questions [3]
Question 1
Merge overlapping intervals from a list of time ranges
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
