BAlite,
I've heard the same thing, I called them up but they told me that they were not planning on hiring in the near future.
Same for Iberia, pilots work a lot, training pilots are saying that they'll be hiring soon as they think they need people but those are false rumor.
I think pilots have the impression that they are overworked.
By the way, Air Nostrum and Iberia have spanish cockpit, so you'll have to speak spanish.
cheers
