There is no universally preferred format. Many job seekers spend days perfecting their resumes, agonizing over whether to use a chronological format or a functional one. This question may be akin to figuring how many angels will fit on the head of a pin. There is no one perfect resume to suit every employer's needs. But there is a perfect resume for a specific opportunity. If you are going to focus on perfection, do it on an individual, rather than a global basis.

Every job is a self-portrait of the person who does it Autograph your work with excellence.

Your biggest opportunity probably lies under your own feet, in your current job, industry, education, experience or interests.
