It often forms the first, and if poorly written, the last impression on an employer. As an advertisement of yourself, your resume should be designed to entice employers to meet with you.
Employers are interested in people who know what they want and why.
Until you know what you want, you cannot write a strong resume. Once you know and can express your skills, strengths, and goals, the direction and style of the resume will fall into place. As you sit down to write your resume, keep in mind that the reader will probably have a large number of resumes to review and will usually expect a clear, concise, one-page document. Use the active voice and keep your phrases simple, clear, and direct. The process of writing your resume will help you decide what particular type of resume best suits you and your goals.
