What are these AMS jobs y’all have?

Purely innocent question, and a break from the usual discussion post drama but I’ve Seen a lot of strat girls (and some guys) all over the AMS events IG and other media platforms posting TikTok’s and stuff and honestly wondering what position or job these ppl hold with AMS. Cause they’re not elected reps right? Or council members? I don’t see them listed but they’re posting for AMS and in AMS vids so are they like brand reps or social media workers? How do you even apply for those positions like what are they? Are they paid? Genuinely curious and I couldn’t figure it out through research.
