I applied online. The process took 1+ week. I interviewed at Capital One (Redding, CA) in Jan 2021
Interview
I know in the world of Zoom interviews, it is hard to get a feel for people. But the interviewer had such a no-energy, bad vibe out of the gate I just knew his mind was made up before we even started. His questions were even irrelevant. I know there could be 1000s of reasons why, but they are selling their company to me as much as I'm selling me to them. I'm 50+ years old, this was by far my first rodeo in this situation but it was the longest, most awkward 30 minutes. I was completely qualified for the job so (in my mind) so it came to would it be a good fit. Never heard anything back. It takes one minute to say thanks for taking the time, but we decided to other candidates. Not sure if they realize that I would never re-apply and discourage anyone else for applying. To be clear, its not because I didn't get further in the hiring phase. Its because the interviewer and process was so bad.
Interview questions [1]
Question 1
Questions were very generic:
Tell me about your current job.
Why do you want to work here
Salary expectations
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
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.
