best of luck to all who have a sim eval coming up. I had mine in Feb, passed, and am waiting for a start date.
My best friend for the interview was Google. Punch in any of the topics you want to study, and out will come reams of articles on everything. Some will be basic, and some will be PhD thesis on aerody, but there is some priceless info on the net.
Do an interview course. They are worth every cent.
Do a practise sim, and be honest if they ask you about it.
Focus on personal questions. Why cathay, strong/weak points, travel history, examples of stress. This is far more important than the tech stuff.
And get as much sleep as you can before the interview. Do not stay up until 2am reading the last few pages of HTBJ. Get at least 8 hours minimum.
Do not at any point think that you have blown the interview. You will be surprised. I was.
Best of luck
