Keep your pants on everyone. To the people that got the call; what is your experience level? Up until now I haven't seen anyone with experience saying that they have been contacted. I'm sure they're going through a shedload of applications as it is. So give it some time.
I wouldn't be surprised if in the end I don't get a call, despite having experience and currently working for an airline. That's the market nowadays and it is completely random. Maybe they even get enough applicants through the process before they ever reach my application.
In the end of the day, sit it out and see. It's not the best deal in the world but it would be a hell of a start for lowtimers. Good luck to everyone that got called. One word of advice though: Don't **** up, you don't get opportunities like this every day. ;-)
