Since i was from Core engineering branch, the questions were limited to my projects. They asked basic questions about C programming which was my 2nd semester subject. Questions like Characteristics of C++, Function calling, Overloading, Stacks, Linked lists were asked. If you are from core engineering branch, brush up your basic knowledge about pumps, compressors, etc. (although it doesn't matter if you answer them correctly). Satisfactory Knowledge in programming would be an added advantage.
