I applied through a staffing agency. The process took 1 day. I interviewed at Convergys (New Delhi) in Jul 2012
Interview
Over all it was technical intensive. There were two written test, one HR round, one telephonic round (accessing communication skills and technical skills), and two online test. In difficulty, level of tests were above average. Even though I got a full training for windows, they were looking for people with good knowledge of windows.
