TATA ELXSI interview questions

Written Test,Hr nd Technical interview The first round was written.Set of questions about operating system,linux and quants. many people were selected from the intial round .Say around 35. Then they took an hr round.(note they send you first for hr or technical depending on which person is free).Had a nice chit-chat with hr.Clue-Try to be as cool as a cucumber .....if this helps. Technical interview was for 15 mins at the max.I was the last person and my friend had gone previously.Had some idea and as funny as it sounds.I got the questions in same order too... At last they announced results and around 25 of us had cleared. Note:High probability of getting selected if we clear first round.As they take the cumulative score of all three rounds.If you do it well ,you stand a good chance
