Pick an easy-to-read font for your résumé. It may be printed, faxed, scanned, or copied before getting to the person doing the hiring.
Edit, edit, edit. No one’s going to read your entire résumé (sorry!), so get rid of the excess to highlight only the best stuff.
No need to list your references on your résumé. If employers want to contact them, they’ll ask you for the info.
Are you consistent in your “branding”? If you’ve got an online portfolio, coordinate the fonts and layout style with your résumé. It’ll help employers remember you.
Be professional in your résumé, cover letter, and job application emails, but don’t be too formal with your language. Employers hire people they can relate to, and the way you communicate has a lot to do with that.
