First of all, working in Macao requires a work permit, which can be divided into technical and non-technical types. Technical type is generally aimed at some technical and academic industries. Of course, the requirement is to have a certain degree and engage in technical or management industries.
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 in general, Macao enterprises will basically go through intermediary companies if they want to recruit people in the Mainland, because there are many procedures to be handled, all of which are done through intermediary companies.
Because I study here, I look directly at the advertising company here, and then all the relevant procedures are handled by the company to find other intermediary companies.
I hope what I said is useful to you.
