In addition to providing a factual representation of your background, your resumé serves as an advertisement of your availability.
Although there’s no federal regulatory agency like the FDA or FCC to act as a watchdog, I consider it to be ethical common sense to honestly and clearly document your credentials. In other words, don’t make exaggerated claims about your past.
The best way to prepare a dynamite resumé is not to change the facts
— just make them more presentable. This can be accomplished in two ways:  by strengthening the content of your resumeé; and  by enhancing its appearance.
Remember, your resumé is written for the employer, not for you. Its main purpose, once in the hands of the reader, is to answer the following questions: How do you present yourself to others? What have you done in the past? And what are you likely to accomplish in the future?
