First, congrats to all the call-getters! Start working hard since the selection process is not going to be a cakewalk for sure.
You know the basics... keep yourself updated with what's happening, know yourself, your academics and your work well and keep talking to people who can guide you.
Once you get your interview form, give it a good amount of thought and fill it well!
Do post any specific queries that you might have... hope to see the best of you'll at the institute next year.
