Not much to add, except that SoftRock is now attempting to recruit via text message. (I am a junior-level recruiter, have mostly been applying for HR jobs, and received a message about a "Customer Service" job I'd applied for, which led me to Google the number). Some legitimate staffing firms such as Spherion recruit via text messaging, but their messages usually start with a descriptive heading like "Spherion Job Alert," and they won't send you text messages unless you've registered in their database and opted in to receive job alerts via text message.
If you get a text message about some bogus job that you never applied for, and if it comes from *******082 or *******662, don't even waste your time!
