Panel will consist of three persons.Two commission members and One from FIA most probably Director of that region in which one appears.
No solid tips regarding interview,Luck and fortune matter a lot.Keep yourself up to date and prepare well.
We have always tried hard and beseech all the seniors to share their experience but none had done the same.It will be much better for every one to ask his friend who have been appeared before any panel,and get some good points...
