As a resume writer, my job isn't to judge the candidate, but to make the candidate look as strong as possible on paper.
My work as a resume writer has led me to believe that much of the talk of worker shortages in skilled employment markets is directly related to poor resumes (and not a lack of qualified candidates).
I get a lot more personal satisfaction out of helping people write resumes and coaching them on job search strategy than I did as a recruiter. But my work has also convinced me that there are lots of people out there who are qualified for the jobs they seek, but simply aren't capable of expressing that qualification in writing.
