4 rounds - recruiter screen, coding round, engineering manager culture fit, system design.
The coding round ended with the interviewer saying "Yeah we probably need a better system to interview candidates - this is a very boilerplate process we have and I don't think it does a good job".
The system design for a web3 role involved 0 web3, disregarded all of my 6 years of web3 engineering experience, had me architect a chat app. The feedback I got after this round ended was "Your system design was too web3. The expectation was a more standard implementation. You also could not explain why you used the technologies you used" while I used exactly 0 web3 elements in the interview, explained why I used certain technologies like Redis and what characteristics of them made me choose them, why WebSockets and not SSE for a chat app and so on. The system design round was composed of a panel of 2 interviewers, where one of the interviewers said exactly 3 words: "Hi, I'm xyz" during the whole meeting. Quite bizarre.
The other rounds were quite typical.
