Clearly pulling peoples phone # off their linked in profiles.  It's a job placement service.. Clearly not legit.

Silence for 10sec. Then thank you..... The do not call list appears on the surface to suck

Answered the phone and a male voice said "Hello, my name's Joesph... and the call ended.

The caller claimed to be calling about an employment survey I'd taken online.  I had taken no such survey nor am I seeking new employment.  Despite being told he had the wrong number, he attempted to give me another survey to "make certain I qualify" for the position.  He never asked my name nor identified who he worked for.

I tested the first few questions to see if I could tell what they were fishing for.  I got:
Are you at least 18 years of age?
Are you a citizen or legal resident of the United States?
Are you or your spouse a member of the armed forces?
What is your date of birth? - At which point I told the man that since I had no idea who he was or who he represented, I was ending the call.

Odd pauses and the way he ignored direct questions make me think this was a voice recognition program rather than an actual person.  Either that, or the person was only allowed to read from a script and needing a lot of time to find a relevant-ish line.

Received a call from this number- my number is on the DO NOT CALL list.  My cell number is not listed anywhere- I only use it for business calls.  I think they are just randomly calling numbers-  555-1212  555-1213.  How can they afford to call?  unlimited cells calls? service provider should track them down by noting excessive calls- wasting valuable resources.  It costs us all in the long run since service providers increase rates for all to pay for these users.
