I applied through the university. The interview consisted of two rounds total. I had mine telephonically and then via Webex. The first round consisted of projects, networking, and basic puzzles. They tested how well we knew concepts. The second round was a video conference and was more of a programming round. Some networking questions were also asked. It was a little difficult. The interview panel was very friendly and made us comfortable. It was more like a discussion round at the end.

What are the networking devices and the difference between them, or where can they be used?

OSI layers, protocols such as ARP and DHCP, and topologies.

Deeper questions on subnetting and puzzles.
