BandaLot, if you are going to mention cost then you need to consider the hidden costs - HR depts expenditure on recruiters sifting through hundreds to thousands of applications which are below the current cut-off standard - even just sending out a generic 'thanks but no thanks' email takes time and effort which is measurable in $$s.
I agree with pilochute that if airlines know there is currently more than enough pilots qualified to 'x' standard why advertise minimum criteria at 'x - 25%'?
