I applied through university. The process took 1 day. I interviewed at Cognizant (Vellore) in Sept 2012
Interview
Campus placement. The experience was good. Friendly HR. Asked some technical and some simple Shakuntala Devi type puzzles. Since it was campus interview so took 2 whole days. Next day announced the result. CTC etc was already fixed so no negotiations. Got offer letter within a month. Interview happened in October and joined on May (after finishing college)
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.
