I had a phone interview where I was asked basic networking questions and some C questions. It was all very simple.

Later, I had an onsite interview with five rounds.

Four rounds were technical, testing my C skills, OS concepts, networking, and past work experience. The final round was an HR-style interview with the hiring manager.

From your network concepts learned academically, explain what happens when you try to connect from your laptop at home to a server in your college. Describe whatever you feel is relevant in this scenario.
