Got an offer late last night for the "Generalist Writing Expert" gig!

Hi all. Yay! It looks like I've landed my first Mercor gig! Couple quick questions for you, though, if you don't mind:

1. The original ad says that it's approximately twenty hours per week for two weeks. But the offer says it's a max of forty hours per week and that I have fourteen days to accept. Those timelines obviously don't line up (and, no, I'm not going to wait fourteen days to accept), so I'm not sure what to make of that? Any insights?
2. How do I know if the background check cleared? I submitted it online last night before bed. This morning, there's a checkmark next to the "complete the background check" task in my Mercor admin panel, but I never received an email saying I passed or failed? I'm in Canada, if that matters.

Thanks! And hopefully see some of you on the inside!
