That looks like direct entry SO. No mention of any Hong Kong ID / right to work required. About 9k usd per month if you're doing 900 hours a year on the current amendment of the handbook. About 6k if you're not hitting the flight pay threshold that month. You'd be behind a long line of SO's, so 6 years seems about right. Up to you. Everyones circumstances are different, as is their tolerance level. Express you'll be paid less, but advance light years quicker.
