I applied through university. The process took 2 days. I interviewed at Cognizant (Bengaluru) in Sep 2016
Interview
Basically there were 3 rounds.
1) Aptitude
2) Technical interview
3) HR round
Aptitude was very easy if u have read R.S. Agarwal.
Technical was bit tough only. They asked everything that i had mentioned in my resume and about my branch subjects (Communication,RF,etc). Everyone who has cleared this round walked with an offer. Guys from non circuit branches were asked puzzles (standard puzzles that you get in geeksforgeeks.com).
HR round was just friendly talk. NOTE: Know everything about your resume. They mainly see your confidence level.
