In the main employment history section of your resume, you can include all the job history you have spanning back 10 years while keeping the resume to one page. If you have had more than 3 jobs, just include the last three jobs but be detail oriented about your job responsibilities. You want to be focused on performance measures showing success, such as, raises received, promotions gained, and valuable takeaways from your previous jobs.
Education is the other important piece of the bulk of your resume. You want to show that you have an education history. If you do not have any educational history, you can always leave it out and add another job to the bottom of your resume. Just remember to keep it to one page.
