Have you already provided these documents to the "employer"? If not I wouldn't until you are sure they are legit.
I have all of the businesses training information linking back to numbers and emails, if it’s a employment scam that was meant to take my identity information then tracking them down would not be to difficult in the event that they aren’t a real business and they try to use my information. I ran some of the phone numbers on the training through a background search and names don’t add up, they told us to be on training calls and they have not been been on which is peculiar. Guess I should hand over the emails from them to law enforcement. Looking up the business on the BBB yielded no results.
