Prepare a resume that describes not only your work and educational experience, but also any extracurricular activities or volunteer work in which you have engaged, as well as your professional aspirations.
Include a cover letter expressing your interest in the site. Make sure you have a specific name to direct the cover letter to.
APA format is not required; however, solid writing skill is expected.
Keep your resume and update as needed. Many states can require this information, so if you keep it up to date, you will not have to recreate it.
