A resume is a “snapshot” of who you are and your accomplishments. It brings together your education, work experience, skills, achievements, and other useful information in an easy to read format. The purpose of a resume is to emphasize your best qualities with the goal of securing an interview.
Your resume is completely customizable. You choose what headings to include and in what order to place them.
A cover letter lets you show a personal side and demonstrate why hiring you is a smart decision. Cover letters should be around three paragraphs long and include specific examples from your past experience that make you qualified for the position.
