1.) A month is plenty......i would read HTBJ and the technical book and then about two weeks prior really hit it hard. BTW there are no math or nav propblems on the initial interview.
2.) Don't delay yur interview...this is NOT the toughest technical interview. They just ask questions that most other airlines don't. Between aviationinterviews.com and this board there is no reason to not be able to findout EVERYTHING they will ask!
3.)I did not do prep
4.) I'll worry about sim prep if I make it to round 2 in HKG
Good luck
I interviewed this week and find out next week.
I left thinking I did ok but not great so we will see. BTW, it was the HR stuff I'm questioning.....I did fine on the tech and that is the stuff you were asking about.
