Most times, what can make it or break it for an applicant is how his/her resume is formatted and presented. One has a higher chance of getting hired when they have a clear and comprehensive resume—a resume that contains no fuss whatsoever, direct to the point, and well-detailed.
One way to achieve that kind of resume is to make it short, but substantial. Use professional looking fonts like Seriff fonts, and limit your font size to just about 11-12—this allows your content to be short, but still easily readable. But it's not just about font styles and sizes, what really makes a resume great is how well-detailed all the essential information is— but don't make it too long. Keep each part of the resume no more than five lines long.
