hi puys,
I have attended the GD/PI on 15th. I am a fresher doing engineering. I will say about the whole process,
First, there will be a presentation done by the students about BIM. Then depending on your name on the list, you will be called for GD or PI or Certificate verification.(Anything may be done first).

About GD,
As far as I heard from the candidates those who have appeared(I was there for 2 days) all the topics were general only. no topic was related to current affiars..My topic was "youngsters go for branded products"...All spoke well and decently.....The type of GD depends on your batch mates.....other GD topics are like
"youngsters like ancient music and art",
"unlearning the process of learning" and stuff like that..
maximum there may be 10 candidates, you will be given a topic and givan time of 1 min to think...they ask us not to use any paper....then they will give a bell signaling to start...then after 16 mins a bell will be givan signalling that only 2 mins are left....then after 2 mins a final bell will be given....
after that you will be given 5mins to write about the GD.....
then interview......

before you enter the panel, they will go the form that you have filled. so be through with the form...questions will be based on what you have written in the form.....for freshers tell about yourself question will be there.....and for freshers, questions will be there on acads......but all the questions will be basic....the panel will be very friendly,so dont worry....

All the best for all.....

Be cool and finish the process....
