I also received a call from this number: 302/526-5040. The message was garbled but it sounded like the woman was calling from Bankers Life in Dover, DE. And that was all I understood.
I received a message from this number also a day after posting my resume on monster.com. Then a second call a few hours later. They said they were calling from Bank First Life out of Dover, DE. Sure sounds like a scam to me.
