He will tell you that you applied for a job on his company's many websites. He won't be able to tell you what website or what job. He isn't calling about a job. This is a scam. He is a fraud.
This is a fraudster. The folks at the other end of the number use different con stories but they have details about you they should not otherwise have. You will be sorry if you even answer the call. Answer 1 time and they keep calling.
