I applied through a staffing agency. The process took 1 day. I interviewed at C&C InfoTech (New Delhi) in Nov 2015
Interview
When you arrive, you will meet your selection board (usually two or three people, including the supervisor of the position and a representative of Human Resources). The team leader will tell you what to expect, and will explain that the board will be recording your answers for later review. Don't let this recording process distract you—it’s a normal part of the interview and necessary to make a complete assessment later on.
