As a new recruiter to RP, what information do you like to see posted about civilian positions? Also, what do you look for in a new employer?

That first one you mentioned is important. That demonstrates that the employers understand who will potentially apply (career field, skill identifier, etc), it gives the vet confidence that their application will be actively considered. It will cut down also on unqualified people who apply via resumes-in-a-tshirt Cannon to hundreds of jobs hoping something will stick.
