888-537-4936

This phone number is associated with a bunch of websites that begin with a state name and end with Professional Group (e.g. "Texas Professional Group," "North Carolina Professional Group," etc.). They appear to be websites hastily thrown together advertising various "local" jobs and they cross-advertise on job sites like Craigslist. Beware; this may just be a scammer trying to collect your personal information.

888-537-4936 = SCAM
This so-called "Local Recruitment Experts" are just trying to get personal info from potential job-seekers in craigslist. The answer machine always responds something like "Thank you for calling the Professional Group...all operators are busy at this moment assisting other customers or they are away from their desks..."

Yep, 888-537-4936 is indeed a SCAM.
"The Professional Group" is just a fictitious company used by scammers targeting people looking for employment via Craigslist
