It's not always 500 hours line training. And as said before, SAS takes 737 type rated people with les than 500h on type, Primera Air was looking for pilots with Just the rating and above that, Norwegian has a Large order which may not all arrive in 2015(i believe 14 738 are arriving in 2015), but they Will definitely need people the upcoming years. It's not the best deal(I wished the contract would be more than Just three months) but you can look at it both ways(optimistisch or totally not).
I have been invited, have a Swedish license(completed at a Swedish FTO) with almost 200h. I can read norwegian en swedish(many words are familiar to dutch), but haven't written it down.
