It was comparable to the other reviews. First their recruiter aligns expectations with you, and the first round is a technical assessment using Codility. It was relatively hard for me because I hate leetcode, but somehow I passed that first round. 2nd round is system design, which I thought went better than the 1st round but that's where I failed.
The only feedback given was that I should have been more detailed, but the interviewer himself seemed to want to cut the interview short. Perhaps they want the candidate to start throwing out specific libraries and frameworks?
