First contact was on zoom with recruiter. Pretty simple screening questions about what I knew about the company and my career goals. Second contact was with a hiring manager. Only 2 questions were asked: what’s TCP and UDP? Tell me about a time when you dealt with an angry customer? Third contact was a technical assessment with questions related to: General command line /SQL information, NAT, TSL/ SSL, TCP/UDP, full OSI model layers, real life scenarios about how to resolve network issues (latency issues, connecting to websites), &DNS. I honestly studied like I was taking a final exam . It is so much information to know. And It was 10-15 questions. Good luck
