I worked for Wizz in Poland for 5-6 months, around 5 months ago and I loved it. It was hard work but it was fun and enjoyable and a fantastic training/experience building environment for me. Things can change of course, and I've heard that there is a new Chief Pilot now.
As a young and growing airline with plenty more 320s on order they will have an ongoing need pilots and the demand is certainly there in their chosen markets.
The crews are nice, professional and pleasant and the flight deck is a truly international environment.
The reason I left was principally financial .. what was on offer was not going to contribute much to paying down my training costs.
Enjoy
