I love this discussion. Rumours based on second hand informations. What is the problem in the conditions offered by WIZZ? You don't pay anything for the type rating, in exchange, you sign a training bond. If you leave before your 3 years are up, you have to pay. You get salary from the first day you start your type rating, and a contract (choice of direct or contractor) which might not be up for some guys, but still decent enough among low cost airlines. If you don't like it, than go for Emirates, Qatar, China or wherever you feel, you are more valued.
Not everybody has logged thousands of A320 hours. Neither can everybody finance their own type rating. Or pay the P2F program. WIZZ is quite OK for them. Top Guns, not so much.
