Social engineering is more two sided. You are trying to get something out of these people, like something very concrete. This is more propaganda.

Propaganda also may try to get things out of people: consent, votes, etc.

Those people generally don't put it on their resumes, having Facebook on your resume is now something that makes it end up in the trash.

I disagree. I’m looking to recommend that a company I consult for hire an agency specifically and solely for their facebook advertising talents.

I am not the ultimate authority at my company but I get a small amount of input. And working at Facebook is an automatic pass now.
