If the resume is from a recruiter representing the candidate, the document may be the victim of the recruiter's efforts to standardize, embellish, or somehow make it better fit their hiring process. Candidates should know exactly how their resumes are handled once they've been submitted to recruiters or hiring agencies. That doc you worked so hard to perfect may have been altered just enough that the writers with whom you will interview (who are most likely the most nit-picky set of eyes that will view your resume) will not give you a second look.
