A "resourceful" person has a certain kind of intelligence. They're able to accomplish a lot with limited resources. Here are some examples of people that you could describe as "resourceful":

• a mother who doesn't have much money, so she sews her children's clothes by hand
• a teenager who forms her own band and sets up several live shows on her own
• an employee in a company's Marketing department who comes up with a great promotion for the company that doesn't require much money
• an action hero in a movie who fights against the bad guys using only everyday materials that he finds nearby

Companies often want to hire "resourceful" employees because they will get the job done, no matter what.
