<prompt> Human: I have a 3rd party recruiter asking me for it to set up an video screen for a client shes working with not give me the job yet...or an interview.I asked her why and she said its for candidate tracking and that no other set of 4 numbers will work. She also said she needs it ASAP.The recruiting company looks big and is US based. I looked uo the HQs number and tried calling the HQ to verify that the recruiter works there but their phone system is down.I dont know if its safe to do it or not. What do you guys think? Has this happened to you? I kind of feel iffy about it. Someone suggested to make up 4 numbers and give it to her. Is that advisable or should I tell her I am not interested in the job. I have no reservations to give her my full SSN after shes hired me  <response>: I would absolutely give her four numbers, but they wouldnt be related to my Social Security number. Thats reserved for employer on boarding.
