A "recruiter" who saw my resume on Monster.com or Indeed.com. I get these calls once every few weeks. They call from one area code and number and leave an entirely different area code and number. It's probably a stay-at-home job and these people are paid for how many calls they make. Sometimes they call back later in the day, sometimes only once. It's a scam. If you don't know the number and it isn't even in your state, ignore it.
