Be consistent and appropriate with your design. Use the same font for headings throughout your resume. Use a smaller font for detail. Anyone reading your resume should be able to tell at a glance what you do and where your professional interests lie. Write your resume in reverse-chronological order, listing your most recent position first.
Most employers prefer chronological resumes to other types of resumes.
Place your name and contact information where they will be clearly visible. Always, Be accurate. If those summer jobs during your teenage years don't have anything to do with your presents skills and interests, don't include them on your professional resume.
