Simply put, why would they be setting up a cadet program with apparently sooooooo many awesome people in the talent pool?
They realise that they cant keep pilots, especially when the worlds economy's start to produce confidence.
Cadets can be locked in for long periods, are naive enough/or desperate enough to pay big money to be trained without guarantee of a job. And this helps QR keep the perceived competition high, the perceived illusion of 5 star airline equals five star treatment of staff etc. wrong.
If you have been waiting for more than 18months then chances are your not being considered. The way i see it, is bet on the rest of your life, not on waiting for QR to give you some kind of freedom/career! Wasting your life waiting.
Good luck to ya
