do you play any game? tell me something famous about your native place.

they are generally looking for students who have good command on there basics so i suggest you to read the book "basic
electrical engineering by V.N.mittal.almost every question is from this book only. one more thing i want to suggest you
that they are also asking what is your favourite subject and then they are asking question from that portion only so it is
better to make good basic command on any one of the subject it may be either power system or machinery.

it was a very nice experience .they were very friendly so i enjoyed the interview and they are also giving you full time to
think and answer.
