A few answers.
TAX is about 5% (blended) on income. None on savings etc. Or booze!
ROUTES include Jakarta, Male, and daily charter to Haiphong right now. Route negotiations are ongoing. They want loads more routes, but there are political problems getting these. Expect some modest progress over the next year.
Any valid ICAO licence is acceptable for conversion in Macau.
AIRCRAFT depend on routes. More routes = more acft. ie expect slow painful progress due politics.
RATING. If you hold valid rating albeit with no experience, I believe you are still qualified to fly in Macau. ie not a licence issue, more a decision if CP wants someone with no experience at this stage.
INTERVIEW/BENEFITS no idea.
SCHEDULES just look up their website, and the Macau airport website for the Haiphong flight times
