And they reckon it's cutting out a lot of CV's that they no longer receive from pilots they'll never employ - ie those without a 737 type-rating in the first place. More than just a slightly bad attitude but it certainly isn't a sellers market out there. Btw, they've never really been into taking people on as a first job, so you're not missing out on much.
They may be building up a dam of resentment amongst the wannabe community but remember that in good times, whenever they employ a 737 rated pilot or even one with some previous experience, another vacancy opens up further down the line, which may just get you your first job.
Good luck
