They really focus on topics from core computer science subjects like interrupt service routines, deadlocks(asked to code it too), semaphores, scheduling in operating system then from computer networks like role of all the layers, TCP, UDP. Was asked if comfortable in UNIX/LINUX. Few coding questions were asked to like swapping the bit at two given positions. How does recursion happen, like flow of a recursive program, tree traversals.

State any physics law that you know of and give an example
Interview was quite different compared to other cisco interviews. The interviewer was extremely rude. He didn't even start with introduction. He asked some OS and Linux concepts, which I answered correctly but he was not convinced for some reason.
