What sense of you do you want the employer to retain when s/he finishes reading your resume?
First, you want to be memorable. Almost always, the person hired is someone whom the employer remembers after sifting through multiple resumes without having to go back through them in detail to trigger his or her recollection. You want something that you said in your resume to “imprint.”
Second, you want to leave the employer contemplating the way in which you have distinguished yourself from other candidates for the position. In other words, separation.
