If you answer factually and have been credible in your reasons for who you have applied to and why there is unlikely to be follow up questions. It is all about preparation doing all your thinking and decision making before the interview. Is that what you were getting at? I assist pilots in reaching their career goals and regularly deal with Qantas, Cathay Pacific, Dragonair, Jetstar, Virgin, REX, Emirates, Singapore airlines with 90%+ success rate. I joined this forum to offer some free advice.
