I applied online. The process took 1+ week. I interviewed at Capital One (Toronto, ON) in Jan 2017
Interview
I applied online as part of a conference I went to and was invited to the first round interviews. I was given a take home coding assignment to do before the interview, it wasn't very hard, took me around 2 or 3 hours. I had a skype interview with a manager and an engineer where they went over my assignment submission and asked some technical/behavioural questions. I received an offer following the interview.
Interview questions [1]
Question 1
Why did you use this approach? Could you use OOP to do this? How could you improve on your solution?
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.

Question 1
Design a rate limiter using a token bucket algorithm and discuss how it would handle bursty traffic and distributed deployments.
