I received a call from 411-212-736-5100 (on caller ID) at my work.  Elwood Staffing.  The caller was asked if there was a message and they said no...when could they call back.  Our company uses Sterling Testing Systems for background checks.  I would think that they would have left a message to why they were calling if it pertained to Elwood Staffing.

Please advise.

Received, did not answer.  Msg. left from Sterling Testing, a background investigation company that got my name from an H.R. tradeshow that I attended in 2007.  I returned the call and asked to be taken off their call list.  After their attempt at not letting me go w/o a sales pitch, they said they'd take me off their lists.

Received 4 calls in 3 minutes ... did not answer and no message left from them.  Called back to get the main Sterling number and the standard menu selections which since I don't know who they are calling about doesn't help.  These days I know so many people looking for jobs / references that the verification agencies are going to have to be a bit more forthcoming if they want info from me.

someone called, repeatedly, 1st was blocked ID, then with this 212-736-5100 ID showing, but voice mail reviews nothing but silence for over 30 seconds, then a little cough (clearing of his throat) then hung up.  

Well, if you have the time and effort to call, make sure you get your message across.

If you have something to hide, that's how you should behave, by keeping silent... but then, why you show your caller ID when it's widely published that you are an annoying spammer?  

Go figure......
