I applied through university. The process took 1 day. I interviewed at Cognizant (Chennai) in Sept 2014
Interview
very easy and more about co-curricular activities than field knowledge.they ask simple programming questions if you say,you know only basics and if are from non-CS/IT background.they will give stress on your communication and your hobbies.And questions like- why do you want to join cognizant?
Introduction
Basic of Oops and Programming
2 Coding Questions
Reverse String and Number
Question on Java and SQL Spring Boot and Other programing related questions like hashing map vs hash table why they are used
It was three round interview with written test and 2 easy interviews. One technical and one with HR for compensation discussion. All were conducted on the same day. In order to get selected need to stand out and answer uniquely.
