I applied through university. The process took 1 day. I interviewed at Cognizant (Mumbai) in Sept 2014
Interview
Campus Placement : First There was aptitude test. Questions were based on c and c++, quants, verbal. After that, in technical round they asked related to c and c++. They even asked questions regarding my undergraduate background. Question were based on Project as well. It was quite simple. And finally the HR. Interview was quite simple.
The interview was primarily technical, concentrating on C#, .NET, SQL, and API concepts. Questions tested understanding of core principles and practical application. The process was straightforward, professional, and focused on technical depth.
I applied online and got a calll back, had 4 rounds in total. first was a behavioral phone call just casual talks about your skills and when can you start working and general questions, then two coding rounds in hackerrank - was asked to code in java although the job was for python and finally HR.
3 rounds of interviews with a technical interview. The technical interview involved questions on Java and sql. They were mildly difficult. The first 2 rounds were not so difficult, lots of situational judgement questions
