Telephone interviews
As far as I am aware they do not conduct interviews over the telephone. they are really strict on appearance, it would be impossible for them. In fact I am sure that no airline would do it other than an initial telephone interview like Qantas. Your best hope would be to go to an open day somewhere that is closest to you, for instance in the States or South America and if it is an assessment day and not an open day then you must apply but put an address for that country otherwise your name won't come up when they are searching their database for applicants for that region.
