I applied through university. The process took 3 days. I interviewed at Cognizant (Hyderābād) in Apr 2016
Interview
first round --Just a minute (topic: your favourite hero)
second round--written exam(AMCAT)
third round -- technical
fourth round -- HR
The first two rounds were simple but the third round is completely based on your luck if you go to a good panel you will be selected without answering basic questions and few panels are really tough to go through.
