So all, the important thing to remember is to brush up the basics of C, C++, DOS and Data
Structures. Special emphasis also needs to be given to RDBMS as it is an up and coming
technology. You might also be given a small section of a program code and asked to either predict
the output or identify the compilation error if any.
So don’t panic, be cool and feel confident; and of course a bit luck is always helpful
Speak clearly and convince your answers to them. Don’t rush at your answers and end up
stammering, getting confused. Speak slowly and steadily; such are the guys who impress more.
Smile in between (if you don’t know the answer) and don’t make too many hand movements. Don’t
use complex terminology, which you don’t know. (Practicing mock interviews really helps a lot).
