Cognizant Tech Leader interview questions

The hr told the interview was scheduled. But around 200 ppl turned up for interview.. The recruiters seemed amateurish n confused.. They din't call us till afternoon. Then there was a written 1st round. Cleared it n then there was a f2f round. It was about 1.5 hrs n contained java, J2ee , spring, hibernate n db related questions. It was intense.. Answered quite well After complettiin of 2 nd round it was around 4 and hr dint even bother to tell me whether I am selected or not. Straightly he asked us that they would be calling us next week and telling the result. But they never called.. it was utter waste of time..
