picky creators, how long does it take to hear back from a campaign?

Very. You only hear back if selected.

it can take weeks or months if you don't get selected they will still send you an email saying why and you can reapply in a month or so again. I find that they live up to their name when selecting picky creators. lol they are picky and looking for great content creators between the ages 20 and 28 or at least that's what I have noticed. I have rarely seen a picky content creator that's more than 30 years old.
