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.
Once you have written and organized your information according to the type of resume you have chosen, be sure to format it according to typical professional standards. You should use consistent spacing throughout, and evenly sized margins on all sides if possible. It’s generally best to stick to your word processor’s default settings, but in some cases, if you shrink the margins on the left, right, top and bottom, this can help buy more space to fit your resume on one page.
