HCLTech Graduate Engineering Trainee GET interview questions

There was a two technical rounds and one online HR interview. It was good experience from them and I have got some clear cut ideas too. The interviews has taken so much time and it was so difficult too

Cleared Online Test,Group Discussion ,Technical Round-1 interview also and finally shortlisted for TR-2 which was done in campus face to face. No Introduction asked and he he introduced himself.Asked only just 4 questions and i got eliminated here.
