Actually they are not recruiting First Officers. They are recruiting CADETS and Direct Entry Captains. What makes the company more money: a 0 hour cadet who needs to go through an integrated ATPL or a pilot who may have tons of hours of experience and doesn't need to go through the whole deal. If you have experience and some hours, there is no need to apply, because you are NOT A CADET, therefore you are not attractive to the accountant's balance sheet. Simple!
