There were 4 rounds. 1st round was screening with basic Linux and programming questions. Not so difficult. Then group technical discussion with a group of 5 people. That interviewer was a knowledgious person and supportive. Details of Linux was asked and you can challenge others answer and you can show your passion over there. Then selected for VM round that is scripting and basic server configuration. There was around 20 questions in 2 hours. Little difficult if you are not in touch. Free to use Google. Then HR round. Basic discussion on job and CTC. People were very helpful especially HR manager and tech guys with nice behaviour and patience. Though interview was tiring but a very good experience.
