First of all, to work in Macao, you need to apply for a work permit, which can be divided into technical and non-technical types. Technical types are generally aimed at some technical and academic industries, and of course, the requirement is to have a certain degree, and the industry you are engaged in is technical or management.
Non-technical jobs are more general jobs, such as waiters, cleaners, dishwashers, or construction workers in hotel restaurants.
I think if you want to work in Macao, you need to find some intermediary companies that specialize in Hong Kong and Macao, because generally, Macao enterprises will basically go through intermediary companies if they want to recruit people in the Mainland, because there are many formalities to be handled, and they all do it through intermediary companies.
Because I am studying here, I directly look at the companies applying for the job advertisements here, and then all the relevant procedures are handled by the company with other intermediary companies.
I hope what I said is useful to you.
