I applied through college or university. The process took 1 day. I interviewed at Cognizant (Pune) in Jan 2008
Interview
Interview was basic set on Java technology. It was not in much depth and they checked mainly the basic concepts. It was hardly of 20 mins. There was a aptitude test before that which was for about 2 hours. It was not difficult.
On the first day we had introduction sessions and we played some games with the HR team....yes all 90 freshers those who joined on that date. HR communication was very good. No company accommodation was provided even for a single day. Work culture is good. In the first few days we were addressed by some very senior people in the company.
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.
