Cognizant Programer Analyst interview questions

Cognizant had conducted walkins and more than 1000 ppl turned up to attend the interview.They were not prepared to handle big crowds.The representatives were not very accomodating and every thing was in a mess.The initial round was technical and the interview was conducted for half an hour.I managed to clear the first round and was made to wait for 7 hours for the next round.The panel was frustrated and they vented out the frustaration on the candidates.Overall it was not a very pleasing experience.
