I applied through college or university. The process took 3 months. I interviewed at Cognizant (Chennai) in Jan 2011
Interview
Hired at Off campus interview. Simple and straight - you clear aptitude, might be bumped with GD, then a technical interview (is not a computer science graduate, don't worry they'll ask question only from resume). HR will be the last.
They are going to look for the attitude and when you are given a chance ask about mentorship programms and sporting spirit in cognizant. Mention that you know Cognizant take cricket seriously and add how about others?
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.
