It's just a job. Grass grows, birds fly, waves pound the sand. I just beat people up
Muhammad Ali

You know you are on the road to success if you would do your job, and not be paid for it.
Oprah Winfrey

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.
