I applied through college or university. The process took 1 day. I interviewed at Cognizant (Noida) in Sep 2015
Interview
It was a campus recruitment drive in our college, they came and took aptitude test which was conducted by AMCAT. I cracked the apptitute and next was a very simple process, just an interview (very easy) Interview person was very kind, he gives time to make you relax while interview,
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
