How did those salespeople get in? How come I haven't seen any recruitment?

Generally speaking, people should be recruited before the opening of the property. After all, if there is no property, employees will be paid to stay there.

Go and see if there is a real estate sales center under construction in the local area. You can call their company yourself and ask if you want to recruit people. Of course, it is ok to submit your resume in the talent market, but it is better to take the initiative to call and ask. After all, sales need initiative.
