Ah guys.... They still have people leaving left, right and centre. They just can't train people quick enough. There aren't the sim slots available, not enough line trainers to get the line training done, and the recruitment department was always a bit slow anyway even when they only needed to recruit a few people!
Keep sending in CV's. If you've been told you're in the hold pool, phone and remind them who you are. It's not been unknown in the past for people to be sent a rejection letter when they've been in the company for a few months already!
Looks like revised contracts are heading the way of new-joiners. Make sure you read VERY carefully. In fact, they'll get you to sign it all on your first day. If you get offered a job, make sure you get a copy before you start so you can have a good read and suss out all the little writing....
They still need crew. What with the order of 20 more Q400's, it'll probably be a continual recruitment over the next few months.
Continue to phone and pester nicely. Otherwise you'll be forgotten.
