The text message I got is "Hi, I'm Jill. Based on your resume you match a position I'm filling. If you register at jobnab.com we can discuss the details if you're interested." It appears that jobnab is a headhunting service. I've registered with Monster, SnagAJob, Indeed, and CareerBuilder and applied to numerous companies through their application interface programs (Taleo and others). Yes, I've been applying to many jobs and there's no telling which site they got my info from. When I tried to do the reverse phone lookup, it seems the cell phone is registered on the north side of Chicago.
I got the text and went to the website. It's a job matching service that interviews you real quick to see what kind of job you're looking for and then sends you jobs in your area that you can go apply for.
Here's what happened when I went to the site. I filled out two pages of information and was given a phone number to call. When they answered the guy confirmed the information I typed in was correct and then asked me some questions about the types of jobs I wanted. Then he said they'd start sending me updates with jobs in my area that meet those requirements. I was given the option of how often I wanted those updates and i said daily. When I got the jobs a few I'd knew already, and a few I didnt. I followed the link and applied for them. Does that answer some questions?
