When writing the descriptions for the jobs you’ve held, focus on what you accomplished in each position rather than what you did. Listing quantifiable achievements in a numerical manner (increased sales 20%, reduced expenses by 10%, for example) will help your resume stand out.
Using a functional resume format is beneficial when you have gaps in employment. The functional resume highlights honors and achievements more than work experience. It lists your skills and other attributes that make you a good employee at the top of the resume. It is important to fill the gaps in employment with experiences that helped you grow. Volunteer work, continuing education, and other projects you worked on during that time are all great options. Be sure to use a positive tone while describing the gaps in employment and be confident about them when interviewing later.
