chances for employment for engineers are quite good, but franky, engineers don't make all that much here. do you have a bachelor's degree or a master's degree? starting salary is around HKD12,000 pm for a good engineering degree and probably less for graduates from a not-as-good engineering school.
in terms of prospects for the electrical/electronic engineers, there's always a relatively high demand for good engineers. but if you're working in hong kong, expect to travel to mainland china regularly if not to station there. possibly long hours and very rough manufacturing environment.
if you have more question, you can ask me.
