I applied through university. The process took 3 days. I interviewed at Cognizant (Chennai) in Sept 2018
Interview
First round was an online test on AMCAT platform with aptitude, logical and English, along with a debugging round where 5 codes needed to be debugged.
Second round was technical interview where most questions were based on the projects done in college.
Final round was HR interview, where questions related to work flexibility were asked.
