‘Overworked, underpaid’ humans train Google’s AI

I'm a contractor for one of these companies. It pays okay ($45+/hour) if you can pass qualifications for your area of expertise but the work isn't steady and communication is non-existent. The coding qualifications I did were difficult FAANG algorithm analysis questions. The work has definitely gotten harder over the last year and often says we need to come up with Masters/PhD level work or problems that someone with 5+ years of experience in a field would have difficulty solving. I wish I had a regular job but I live in rural North Carolina and remote work is hard to come by.

How often do encounter difficult content? Like gore, violence, hate, etc.? I would think prompts would keep that out of responses, is that naive of me?
