I think the method is that they send you a transfer that will bounce because it isn't a real one, but you have to buy a laptop or development system that will supposedly be delivered to them for software installation and configuration before your bank notices the problem.
They then cancel the purchase before it is delivered (or they may even be the supposed equipment vendor) so no delivery occurs, and the money is refunded to their offshore unnamed account, instead of to the job seeking hopeful.
They get the return money since that's what the company name on the invoice will specify, and you get stuck with the bill because you paid for it with your own money or credit.
