I applied for receptionist jobs to 3 different people and Im not sure if they are scams?

looks like they are affiliate marketers. The credit report will cost you money and they will claim a percentage of that in commission if you buy through their link. I would post a fake credit score and see what they do (aim high but not too high so they can't say no) if they say you can go ahead with the interview then they're probably not a scam.
