One of the main questions asked about resumes is, Do I have to include everything on one page? The most common misconception of resume writing is that your entire professional history has to fit within one 8 x11 page of white paper. The truth is, the resume should be well written and concise, and should promote your qualifications in the best possible light. This is sometimes impossible to do in one page. Thus, a resume can extend to multiple pages, with some consideration depending on your career level.
Be concise. This is critical. Do not use lengthy sentences and paragraph forms to disclose your experience and your education. Employers want straight forward statements that highlight your qualifications. A resume is not a place to show your creative writing skills.
Perfect your resume. You have second to catch your potential employers attention. Make sure that your resume is properly formatted, and you are not trying to fit too much copy on a single page of paper. Create appropriate and professional sections for your resume. Your potential employer is more concerned with the look and content of your resume than with its length.
Longer is not better...
