Welcome to Asia
Some comments with all due respect, sounded like you were a bit behind the aircraft, for check rides I am ultra conservative when it comes to turbulence, not knowing the difference between technique and SOP? Anyway, you weren't at Delta and in the contract world they don't treat you like a valued employee, in hindsight, changing your instructor was a BIG mistake, it probably brought shame to this instructor and may even be part of the reason they didn't pass you, but not following taxi instructions at HKG is a deal ender on any check ride, what were you thinking? I wish you luck, not like you'll have any trouble finding work with your background.
