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.
Also be sure to include your city, state or zip code in your contact info, since employers will sometimes search Applicant Tracking Systems with these criteria. It’s also important for ATS to have this information at the top of your page, otherwise it may not be parsed into your candidate profile, making it harder for HR to find or remember your resume.
