I had 2 interviews over the phone over 2 weeks. The first interview was with my manager. He asked me some basic behavioral questions and some simple questions from Computer Networks.(TCP vs UDP, etc.) The interview was about 40 min. The second round of interviews was one hour long. I spoke to two engineers from the team one after the other. They asked me questions about how utilities like traceroute and ping work. One of them noticed AI on my resume and asked me about some terminologies like Knowledge Base, Inference Engine, etc. Got a call from recruiter 3 weeks after the second interview.
