This is all very interesting but the fact remains that at a recruitment day recently there were 100's pilots queuing through the hotel. This doesn't include the vast number joining from Lot / Eurolot just for the Polish bases alone nor the online applications.
There are lots of (mainly expats) leaving for other operators that is causing some problems for next year's staffing levels, so if you don't like the terms that Wizz offer then don't join, but if you do then go in with your eyes open.
You'll fly to max all year round (myself 892 hours: 510 sectors), rostering and scheduling will take precedence over your commuting, especially when there's a shortage of crew, the salary is a lot less than other operators, and some pilots have been told to sign a new (agency) contract with worse terms or else...
But, if you don't have a job, or want a short time to upgrade, or want to be based in your home country then Wizz are still a very good option.
