Indian recruiter scam - they aren't filling any real job and only harass companies with postings trying to represent themselves even though no self respecting company really ever goes through them except in rare instances - hence why we still have them all fighting for a 200-500 referral see.
Got a call from (412) 200-1197. I did not answer and they left a voicemail. Guy sounded like the guys from India who do tech support and I couldn't understand 2/3 of the message he left. It took me four replays to get the 877-884-8834 number correctly to run a search to see who this number belongs to and reading the posts here to fully understand the name of the company (mastech) he was representing.
It is a headhunter / recruiter based on everyone else's posts and the fact that I was recently laid off due to my previous employer relocating to Alabama, I posted my resume on the major resume posting sites (indeed, monster, and careerbuilder).
Right after this call left the voicemail. I got two more calls in rapid succession with the "Unavailable" posted on the caller id.
