Most of the questions were from communication (go through the basics of analog and digital communication, only the fundamentals). You may expect questions from switching and networking so get ready with the routing, switching and basic concepts of networking. They asked me questions from OSI and TCP/IP suite and tried to delve a bit deeper. So study about OSI and TCP/IP suites and have some fair knowledge about protocols that are assigned in each layer.

Basic technical question regarding OOP concepts and a basic program on arrays. The interviewer was polite and even gave me feedback on how to improve my aptitude regarding these IT questions. A good interview in my opinion.
