Icai campus experience

Hello all my Friends & Colleagues,

I have recently qualified CA exams and applied for our ICAI Campus. I have been shortlisted by companies in this campus also.

Now i wanted to know from all of you regarding your experience in campus, Written Test, GD, HR Round, Technical Round etc.

How to prepare for these things, and is GD conducted  by every company and what they actually want from GD.

Please help guys so that i can get some good offer from the recruiters.

Thanks in advance.
