Hey,
I’ve been on waiting list since February. We have emails each time there is any improvement on the list. Basically, as said above, they are actively hiring for Germanwings, but with a B1 Level in German.
For non-German speakers as myself, the list is quite long, because we can only work for Eurowings Europe, which means only few bases available. For German speakers, it appears to be very quick. We even had an offer with cash bonus if able to pass B1 level certificate and then work for Germanwings.
