In many cases, your resume is the first document a hiring manager will look at when reviewing your application, and therefore is a true “first impression.” Accordingly, it’s important to put time and effort into developing and maintaining an updated, accurate resume.
Think of a resume as “self-advertisement” that sums up your experience on one page. Your resume is one of the most important pieces of your job application. It gives the hiring manager an overview of the qualifications you have for the job for which you’re applying. You should also familiarize yourself with the difference between a resume and a cover letter.
