The most common type of resume is in chronological form and lists job experience starting with your most recent position. Another type of resume is the functional resume, which lists experience and skills in a nonchronological format. A typical functional resume includes a section highlighting qualifications and elaborating accomplishments; another section with places of employment, job title, and dates employed; and other sections with education and community service participation.
Functional resumes are most often used by job hunters with gaps in employment history, and they're sometimes used by people hoping to change careers or those who have had many different types of jobs. Dates of employment are still included on the functional resume, but the hope is that an employer will see past any gaps because the applicant's skills are a good match with the skills required for the open position.
