I applied through college or university. The process took 1 day. I interviewed at Cognizant (Velur) in Sep 2016
Interview
First was the online test based on aptitude , logical, verbal. If selected then is the technical round which is a little tough and finally the personal round in which they ask some tricky questions to check your presence of mind.
Interview questions [1]
Question 1
questions from the various technologies I had studied in my course
Pretty easy. The interviewer was really nice and since I only graduated then from college, he was less strict and focussed mainly on questions related to IQ and standard data structure.
