Advice - just be yourself and RELAX! The recruiters will pick up your wanting it too much and thus you may not even get the call back. Approach this with a cool head (easier said than done). Meditation helps. Google 'brain sync' - you can get something from the brain sync website to help you relax. It works instantly ; sorry if I sound like a telemarketer
. All in all, if it is meant to be, it shall be. Make sure you also project a happy, bright and energetic persona, make friends at the venue and be helpful with the other applicants. It will come back to you. Cheers
