interview process is quite simple and standard. I got a call through elitmus. A lot of people don't know that CGI don't require elitmus score, they just select candidate whom they want to interview. Once you get call from CGI , they will conduct their own aptitude exam. so for applying in CGI you don't need score. they will conduct aptitude , GD , technical I, and technical II round if you would successfully cleared all you will face HR round which is just for name sake.
