I just finished my second interview (literally an hour ago). Here is what I know, in regards to your questions.

1. I have no idea!

2. Living in HK is totally up to you. I am going to be DEFO on the -400 freighter, US based. After 4 years, I can bid to move to HK. The incentive is slight less now than it was not so long ago. The freighter and Pax payscales have merged. I'm not exactly sure how it works, but there is less of a reason to move to HK unless you want to. If you do, then you still get all of the housing incentives etc.

3. DEFO freighter, Freight COmmand, Capt -400 (when able to hold line)

4. I had NO references nor anyone submitting my paperwork. I haven't got the job yet, but i'm very hopeful..

Good luck

Experience.
