In technical round they asked more abt c ,c++ ,computer networks n operatin systems.they asked abt different OSI layers, told me to write IPv4 header format n many more. It was really hectic. It went on for more than 30min.

Then in HR they asked that whether m ready to work if m placed anywhere n wat ll u do if u r placed on bench. then they asked abt d project v r doing in clg n wat is my part in dat. Wen compared to technical round, HR was really good.

first of all prepare well for written test. abt half of d job is done if u crack d written test.
go once through ur basic subjects.Be prepared for some common quest like tell me abt urself,ur strengths weakness,hobbies.

There were 3 rounds.1st round was written test.2nd round techinical interview and 3rd round was HR. Around 300 students attended n among them 70 were selected.
i think mixture of all these.confidence,luck,mine knowledge....etc
