I applied in-person. The process took 1 day. I interviewed at Cognizant (Chennai) in Jan 2014
Interview
Totally two rounds ( one face to face and another telephonic round in their premises itself)
To take up the first round itself they made me wait till 12pm but post clearing the first round the other processes were fast enough that I got an offer by 3pm in the evening.

I applied online. The process took 3 weeks. I interviewed at Cognizant (New York, NY) in Oct 2011
Interview
They reached out in the middle of school cycle and scheduled the interview. The interview was kind of okay and I was selected after 1 round of interview. Then they scheduled client discussion. I was selected and on boarded without formal training. At client location there was no formal guidance from project managers how to work on project.
I would suggest never anyone to join this company.
