Hi there guys, Im also attending the Australian Airlines interview in Sydney on the 6th of June, look forward to seeing you guys there. I also think that language candidates only have a "preference" as customer service experience and you as a person are a bit more important than languages. I speak Mandarin but have not got a certificate from the Languages school as Im not sure of my fluency, I can only speak conversational, but we will see how we go.
Take care guys and I wish everyone the very best of luck!!!
