I applied through university. The process took 2 days. I interviewed at Cognizant (Bengaluru) in Apr 2011
Interview
Its on campus for me and we had 3 rounds. 1 written test, 2 Technical 3 HR. All the rounds are easy , they have taken people in bulk as if they need more and its all marketing stunt
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.
