Resume writing is a skill and should be treated as such. It is important to be brief and succinct in the presentation of your resume.
It is easy to find sample resumes online these days, and there is even resume software out there to help with the tough job that is selling yourself, and showcasing your skills and experience.
No matter what job postings you've been perusing, it is important to take the time to learn exactly how to write a resume. Whether you are writing a student resume with which to look for part time jobs, or you are past that phase and seeking full-time government jobs, do not assume you know the art of the resume.
The most important thing to remember when writing a resume however, is not necessarily following the myriad rules, but attracting positive attention to yourself: in a nutshell, standing out. It is important to be creative but organized, and to keep your document esthetically pleasing.
Find as many sample resumes as you can, learn why they work, and then create your own masterpiece.
