There are a few different ways to format your resume. Choosing the best format for you will only make the resume writing process easier. When choosing a format, you should consider the job for which you are applying. Chronological, functional, and hybrid formatting styles each have specific purposes for the applicant.
You should also include information about promotions in this section. When listing your responsibilities, start with the most valuable experience first, since the employer will likely be skimming your resume top-down.
