I applied through college or university. The process took 1 day. I interviewed at Cognizant (Chennai) in Mar 2014
Interview
First aptitutde test was there of 1 hr.
quants
16 questions in 16 mins and then there logical and verbal part .Those were easy.
After clearing it first technical interview took place then HR.
Interview at Cognizant in my case was a cakewalk. Two people were present in the interview pane. The interview itself consisted of casual questions and cross questions that lasted for 25 minutes. No technical questions were asked . Mostly regular friendly questions
