there's no doubt about it, this is a scam.  And, thank you intelligent people for recognizing the fact that any call from the 215 area code in relation to a job should be scrutinized!  I called after seeing your comments, and was informed, "This is Rebecca..."  After I gave her my name, she asked, "Are you only looking for a job or a business opportunity?".  I told her, "a job of course".  She was in a hurry to get off the phone, however, I managed to inform her, "BTW you should know your scam is all over the Internet".  Good job people!  This economic situation is hard enough, I too am sick of the predators!
