I have received 3 calls from this number, so far, today.  My phone app bounced the caller directly to voicemail without ringing the phone... but they did not bother to leave any message.  If this is a legitimate recruiter for contract employment, they are exceptionally unprofessional and certainly not to be trusted.

Of course, I've discovered that virtually every such call from New Jersey falls into the 'untrusted' category, since I do not know ANYONE in NJ, or on the East Coast for that matter.  But if you are contacting me for a local contract position in Arizona and you are on the East Coast, I'm not going to be talking to you in the first place.  I will apply for the position through a local staffing agency.
