did you ever hear of SUPREME LOAN COMPANY ITNL.?

Answer 1

No...but you can see if they are legit by contacting the BBB or researching them online.

Answer 2

If they sent you an email offering a job where you'd "process client payments" and keep a percentage of the payment you processed, it's a scam. You'd process the payment by putting it in your bank account then sending off a check to the company, only to find out the payment was fraudulent in the first place but the company will have disappeared by then, leaving you holding the bag!
