Gearupandorff,
Give it a go. Put in your application and ultimately you will have your answer. Keep in mind some of the considerations in respect to living in HKG that others have posted. If its not you that gets the job it will be somebody else on the same conditions. Me personally I would rather share the flight deck with someone like you that has an interest in aviation than someone straight out of school who only applied because their girlfriend saw the ad and he just wants to keep his girlfriend happy.
