Cognizant Trainee Programming Analyst interview questions

They started asking about virtual function in c++ which was quite easy but it almost lasted about half an hour. Half hour of virtual function. Nothing ELSE. They just wanted to see whether i was able handle the pressure.

I was asked difference between CMMI and ISO which was difficult. rest were related to projects. The interviewer like to go through one resume noting down achievements and projects that has been undertaken. they might try to test your integrity by asking question like are you being topper of your class(i was asked and then i replied with a suitable explanation).
