The two main types of resumes are functional and chronological. A functional resume concentrates on your accomplishments and experience, with only the briefest reference to your job history. A chronological resume details your jobs in reverse chronological order, the most recent position first. Which do I favor? Neither one!
The best modern resumes are a combination of functional and chronological. They start with a paragraph or list summarizing your main areas of accomplishment and your most valuable skills. Under that comes a detailed job listing, with information on your achievements in each position, in reverse chronological order.
A straight functional resume is often viewed by recruiters as a warning that you have something to hide: a large gap in employment, a history of moving from job to job, or an inability to hold onto any one job for very long. A straight chronological resume may force the recruiter to hunt for relevant experience and skills. The combination resume tells recruiters at a glance that you have the right skills and a stable, solid work history.
