I'm wanting to know if anyone else has heard anything about the Starpoint trading. I answered the ad for clerk

I seen the ad in the Conroe Courier and I sent in my resume and was contacted and received a check and I don't know what to do with it. I'm not sure this is real. I called and searched the web for this comapny and it's real but I can't find Star point and only have an email as the contact.
