Minima beat me to it ..... a mate who flies A330 as a FO at Cathay was a second officer for about 2 years on B744. He's HK based, but manages to get regular HK-Sydney trips, so he can sleep in his own bed from time to time.
In the case of my mate, he had about 4000 hrs, starting in C210s in the bush, then making his way up the GA food chain ..... then B1900s, and finally SAAB 340s for REX before Cathay hired him.
There are very few Chinese HK pilots flying for Cathay. Mainly UK / Aus / NZ / Canadian / US / SAf ..... mix of ex GA and ex mil. The 'S/O' option isn't all that common in the USA, but all Cathay (except freight - it's a different career path) start as S/Os ... as do QANTAS and Air NZ. It's not a dead end, 'cruise pilot' .... although as an S/O there is no handling the aircraft below whatever the company limit is (typically between 5000 & 10000 AGL).
It's not for everyone, as the HK residency requirement is non negotiable (once again, freight fleet is different - UK, European, US, Canadian & Aus bases are available to the freight blokes, but they're all F/O entry).
Hope this helps.
