It is a written representation of your educational background, work experiences and extracurricular activities and accomplishments; your résumé is a self-marketing document that serves to support your immediate career objectives. It is the vehicle by which you convey to potential employers the type of information employers need to know when considering you as a candidate.
A résumé must be able to stand on its own. You cannot verbally enhance and expand its content during an initial review. An effective résumé should have an attractive appearance and be easy to scan quickly; it should also be well-written and concise in content. Your goal is to impress potential employers enough to say, "Yes! I want to interview this candidate."
