All in all 120 jobs in the first batch, spread over Belair, LTU and mainline AB. LTU jobs will be MFF A320/330, however all you can do is ask for a certain job if they take you, no guarantee you will get it.
However new recruitment is open for some time now and AB allready has somewhere between 4 and 5k applications. Good luck anyway, oh, and be sure you can speak fluent german.
