Just got off the phone with Career Network and I called them per request via text message. They offer a prescreen and verification service to its applicants for their employers. The call was brief and was just to verify all of the information I put on my application before it was turned into the management of the job.

877-849-1207 Career Network in not a prescreening for a job.  Career Network is a prescreen for Trade Schools!  Beware.  They are only interested in money for trade school.  Very Misleading.  This comes up when you apply for a job at Career Builder.  You have to be very careful on career builder a lot of the "job listings" are really misleading and really trade school trying to enroll you in "college" that is not accredited with any university.

Recv'd a text to call this number about a position I had applied for. The number is to a verification company. They verified my information was correct and forwarded my resume directly to the company.  Very quick.  They're legit.
