Cognizant GenC Developer interview questions

Good Interview experience Interviewer was friendly asked me about oops concepts 3 puzzles and 2 coding questions it was a half hr interview then I got called for hr round later on

Interviewer made me comfortable and asked basic questions from core papers(ECE).. Then asked some codes and then easy aptitude questions...He didn't ask any questions from my project or from resume(which i expected and prepared)
