Go to storm aviation website.
You will have to pay for a type rating with them and then they will send you out to Poland (Katowice) for your line training and possibly some hours on top. It seems to change what they offer you, but I know many a pilot who has started their flying career with Storm and are now flying 320's in other companies.
On top of your Type Rating costs, expect a good 3-4 months without earning money as you will not get paid anything until you have flown off your Line Training and possibly 300 hours on top.
Accomodation may or may not be paid by storm, but it is cheap out their to get accom and the food and drink is also cheap... approx 6 PZL to a 1GBP, and a beer will cost about 5plz if you find the right places. Food is cheap. A meal in a cheap restaurant about 20 PZL..
You can also dead head back and fro to many of the destinations that Wizz offer..SO you can come home lots too...you are not stuck out there..
Plenty of interesting flying and a good mixture of guys
And "NO"...I did not go through the Storm Scheme...
