The interview process was pretty smooth. 1) Had an initial phone interview that lasted an hour. 2) I subsequently had a 30min call with the engineering manager. He was very pleasant. 3) I then had a virtual onsite with 3 rounds. - Coding round: A simple problem that i was able to solve quickly. They then built on this problem. I was able to explain my approach for the solution and started implementing it (It was obvious that one couldn't achieve the solution in 15mins). - Design round: This round went well too. I was able to communicate and explain my design. I walked them through the different reasoning for the design chosen. I involved them throughout the different choices made. - Topgrading round: Discussion with the manager about past roles held. I was not offered the position citing that i needed prompting in the coding round and that my system design needed more work. This was one of my best performances in a coding interview and i did not need any prompting. Its unfortunate that such an observation/comment was made. I can accept the feedback on my system design and can definitely work on it.
