Rj2driver,
I sympathize with your situation. In my opinion, knowledge is power and the first-hand testimonial is always a good thing.
From what I have heard, both Jet Blue and Spirit in your country are hiring high time RJ FOs (probably to lock them in with no PIC time) and the legacies will be ramping-up hiring soon that will increase slots at all other US airlines (as people leave for Delta and UAL). Perhaps more networking will improve your odds.
As for FlyDubai, it is good to get a variety of perspectives and know what to expect...
Good luck
