There was one round with Capgemini and one with client. Then final round was HR round. Capgemini interview was of easy level. They asked simple C questions, basic OS questions and easy programs. Second round was with client, they were asking medium level questions, from OS, C and 2G, 3G and 4G telecom domain questions.

I would say Interview was easy, no one from Capgemini took the interview, it was conducted by client itself. Once client round cleared, Capgemini manager round will happen. HR discussion also on the same day. Fast process.
