I applied through college or university. The process took 1 day. I interviewed at Cognizant (Pune) in Dec 2010
Interview
Very nice process.
1. Overall information sharing session
2. Aptitude written test
3. Interview which covered technical knowledge testing on programming language like C.
Questions were mostly on Array and pointers.
They also asked and were more interested in the project work done in college.
I would suggest to explain the project and your role in that work.
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.
