Interview Process
The interview process began with HR reaching out directly via LinkedIn. There was no online assessment; the first round was a coding interview focused on a classic problem related to dasher pay. However, there was not much follow-up discussion on the solution.
Two weeks later, I attended the onsite interview, which lasted an afternoon. This included a deep dive and system design session centered around a classic problem, the 3-day donation system. I felt a bit nervous, particularly regarding the async and idempotency aspects, which I did not articulate perfectly.
The debugging round involved a Round Robin problem. My nerves caused me to take extra time, but I managed to complete the solution for Consistent Hashing.
The behavioral questions round consisted of standard questions. Due to my limited years of experience, the manager concluded the interview about 15 minutes early, even with a late start.
I was notified two business days later that I did not pass.
