That's the resume's only purpose. Your resume is your primary personal marketing tool. It is often your first introduction to an employer.
First impressions are of supreme importance.
You want to project as favorable and professional an image as possible. A solid, well written, focused resume can do those things for you. An effective resume allows you to profile your personal, educational, professional, and experiential qualifications for the position you are pursuing. Experts indicate that employers who review many resumes may spend thirty seconds or less reading each one during the initial screening process. What this means to you as a job hunter is that your resume must stand out.
