Some fine advice there by Ratpoison.
I have no idea what the "new" interview process taking place in Oz and US will involve. i.e will it be just a stage one like CX with second round to follow in Dubai, or will job offers be made based on the OS recruiting day and Sim ride.
This is a critical point. Like HK, Dubai is not a place you want to commit to until you have seen it. And more importantly, if you are married, it is essential you bring the missus over for a look before you commit. Happy wife, Happy life.
Many of our colleagues have had their life turned upside down due to the fact their wife can't handle the 'pit, and its enlightened attitudes towards women.
Be careful guys.
