TidaBisa,
Sorry, I haven't a clue about the process, I can only guess it will be simular to Emirates since it sounds like they will run it until flydubai gets on its feet. I have just been told what to bring, who will meet us at the Airport, etc. I think the process I know about is posted on their website as far as it being two days. Day one is Orientation and Sim. At the end of the day they will tell you if you progress to day 2. If not sit back and enjoy Dubai for a day. If so I believe its a Phyc eval, and Medical. I'll update you with the scoop around the 3rd of October.
Have a great one, and thanks for the luck wishing.
