This is a scam involved in identity theft (do a search on WN Positions)
I got this as well. It is a headhunter for medical jobs. I'm in the medical industry so they probably got my company cell phone number from our website. Tacky!!!
Some guy just called me as well stating that I took an online survey which assists people in the area in finding jobs. 1st of all, I don't do online surveys 2nd I have a great job so there's no way I would have participated. When I informed him that I have a job and did not fill out any surveys, he hung up. The number he called from was 316-252-1270
