I had some place call saying my credit application was approved and they needed my checking account number for verification. I didn't scammed, however, I can see people falling for that one.
I was looking for a job on Monster and a company was advertising for a collection position, they forward accounts and you get a percentage of what you collect. However, you had to pay $400 for the software. I almost fell for this scam because it was on a legitimate website like Monster, I did some research on the company and found out they were a scammer outfit.
