If I recall, it was 30 minute recruiter screening, 1 hour discussion with the hiring manager and 1 hour technical interview with members of the team. Overall, I think it was a very pleasant interview process. I was able to insert a few jokes and make some people laugh. The system design part of the technical interview went really great for me. I was able to freely present my ideas and I felt I was able to answer everyone's questions and concerns about my design. Everyone seemed open and welcoming. I honestly wasn't sure if they were interested in me. I believe the interviewers were really tired, so everyone looked and sounded like zombies. But in the end, we're all human and I'm sure they just had interview fatigue or something.
