I too have received a call from this number. In fact, they just tried called me about 2 or 3 minutes ago.
That would make sense. I posted my resume online and ever since then, I've been getting calls from strange numbers. Some only call once and never again, other call all the time. It gets really annoying.
I know! I've got my resume posted, so I want to answer all these calls I don't recognize in case it's a potential employer. Glad I found this before I called them back.
