re: phone call.. if you looked over the thread youd find your answer, but to help you out.. the phonecall from what i remember is pretty much:
-do you have first time passes in ATPL exams and IR/CPL?
-How many hours PIC/total?
-Last aircraft flight ME? (must be one hour logged in last 6 months)
-Rating expiry dates?
-Valid EU passport?
So theres nothing to prepare for, no tech or HR questions at all... its just a screening process.
