I was asked questions on the networking basics and also certain topics related to the network security. Questions were asked on small things like how does a mail pass or how does a computer boot up to check the in-depth technical knowledge. Also various questions were asked on port nos and protocol nos and some questions related to Linux basics . Lastly some personal questions to end the interview
