About the salary:
Either you fly a lot of short sectors, or longer ones which pay more. The compensation is OK for captains, not so for the FOs. (20% extra for sectors above 2hrs, 40% for 2:30+ for PIC, 10 and 20 for the FOs) The average of my last 5 months were around 6200 EUR after taxes, with more than 2000hrs WZZ PIC time.
Nobody is forced on a Confair contract, but almost everybody chooses it as apart from the income tax, you pay all the rest wherever you want. (which is deducted in case of local contract)
I had a selection scheduled for Easy in AMS, but after a quick calculation of the salary, I declined, as it would have been more or less the same...
