Recruiters who request SSN over the phone
icey: It sounds fishy. Is a background or credit check part of your pre-hire approval? If not, there is no reason for them to ask for this information without you being there to fill out a W2, as aristus mentioned.If they can't tell you specifically why they need this information in very concrete details, do not give it out. (I see that you've already given them this information, but be sure to be more careful in the future.)
