[ I feel sorry; I couldn’t add questions from electrical, IT, civil, environmental etc. branches as minorities are always sidelined.
These questions just look simple. They may grill you if your answers don’t look confident or if you try to bluff. If you don’t know, you can say ‘sir we don’t have that in our syllabus’ or ‘sir I am not remembering it’ or ‘I don’t know sir’.
Maintain eye contact with the one you are speaking. While you are speaking give intermediate looks to the other interviewer. When they ask about projects you can spent more time on them, as you will be more comfortable with the projects you have done.
Non-CS students who apply for software companies, should say, they at least know one programming language, generally C; and should be prepared to face questions like what are strings, pointers, header files or simple ‘for loop’ usage programs.
Some software companies ask puzzles in their interview. This is the most challenging job to many people. There are chances that if they solve one or two asked puzzles they may get selected, other wise may get rejected. I have seen many good students struggling with puzzles, with tense and frightened look at the interviewers. Usually the puzzles asked will be simple. So be cool, take the paper and write down the figure representation of the puzzle and analyse it by fully focussing on it. Just forget that in front of you two (or more) enemies are sitting. Many students falter at this stage. One JC student who answered every question fired at him at Satyam interview was finally asked a puzzle.

How do you divide this figure into 7 equal parts?

The boy got tensed, struggled and gave up. He was rejected for not using common sense. By the way the answer was:



So don’t panic, be cool and feel confident. Yes, here a bit of luck is counted.
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).
The technical interview may last for 15 to 45 minutes. With good preparation many people find technical interview easy.
If you do technical badly, then there is 90% chance of your rejection, if it was average, then one can do well in HR and get selected.
