what would a clerical job at a law firm be like?

I want to be a lawyer when I get older, and if not a lawyer, something in that category. I’ve worked at a grocery store and Brusters, but that’s it. My dad knows several lawyers, and he’s offered to get me a clerical job at a law firm.
What would this job be like? What would I do, what would it require? Would I be at minimum wage? What would I be required to wear?
