My guess is that we are talking about Austrian here. If you can live with the rather lowish starting salary now is a good time to join. There are now 200+ NFF on 2-year contracts and only a very small number of these is considering to sign a permanent contract (maybe some austrian citizens who don't mind to lose their ticket to Lufthansa). This means that everbody who joins now will gain a lot of seniority in a very short timeframe. Careerwise things are picking up quickly now with Longhaul F/O positions now down to 4 years of seniority and commands under 10 years, this will however slow down again in my opinion as expansion is uncertain (and very much depandant on what happens in Luftyland).
Generally speaking it is a nice company with most guys being fun to work with and if you live or want to live in eastern austria it is really the only viable long term option.
