Three months ago it was 15K€ deposit (or bank guarantee) for non TR DEC, half returned after first year, half after second. EDIT: sorry, thanks to Search user's posts I can see you are asking about F/O position, I have no idea how it works for F/Os. Give the good folk at SXS a call, they will give you the truest and the latest update.
Bargain of the decade, if one can pass the screening.
