While I don’t belive it is intentionally malicious, this is asking for an applicant to produce free work in exchange for the possibility of monetary compensation and no obligation on your part to extend a job offer.

Further there are no details on the job itself, including expectations or pay.

Being a forever GM I can subject my players to whatever system I want! Delta Green has become one of their favorites.

I can agree that most of Paizo’s adventure paths can be lackluster. I highly prefer PF2e to 5e, but my favorite adventure paths are the 3 part ones, Stolen Fates, Quest for the Sky King’s Tomb, the 6 part ones definitely feel like they’re stretching a plot to reach 6 parts and should have broken it into separate stories or fewer books.
