When you’re working on your brain dump, make sure to include the name of the company, its location, dates of employment, and several bullet points describing your role and responsibilities for each position you list. Although you may need to expand on the bullet points later on, you’ll need this information at the minimum.
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.
