Got a call asking for someone who does not work here.  When I said so, the rude guy on the phone told me he knows she works here since he recently spoke with her.  Ummmm.  No she doesn't.  He made it sound like it was important.

Keep getting calls from this number and no message. Google says it's a printing company called Mimeo, however, their calls are now coinciding with other annoying scamming calls, so I'm not sure if this is a legit number or not. Recieved this call and after I hung up on them, I got a call from 612.852.3650. If you google this number, it is affliated with page after page of reported scams such as credit card refi, payday loans, missing grand daughters who need money, etc.

I have received several calls from this company, Mimeo.  They claim to be able to "print" our company's teaching course ware material". This in effect is asking us to hand over company internal information for resale or whatever kind of distribution.
Bottom line.....SCAM

Mimeo is a real company. I've been interviewing with them and missed their call and had to check the number. They are not trying to steal your info. They are a real printing company.

But ... why are they making unsolicited calls to people who have not applied for a job, or have not ordered things from them?

Can you answer that question?
