I got a call from that number, too. NO idea who it is.

Just got a call from this number. They told me they were calling me about a work survey I had completed. I was suspicious but because I had recently applied for an internship working for my city, I decided to answer the questions as long as they didn't ask for my information. They only asked if I was over 18, what my highest level of education was, if I was employed, and if I was currently in school. When I told the person I was currently studying at big 10 university they told me that because of one of my answers I no longer qualified for whatever it was they were calling about.

I'm pretty sure this person was trying to determine if I was educated or not before they tried to phish for my information.
