Thanks to Brian, I discovered this gem on resumes and first impressions.
I especially like the first point: “Concise – keep it short and to the point. Tell us about your accomplishments as well as your responsibilities. Don’t spend a lot of time talking about strategy, the product, or the company.” Someone with four years of experience sent me an 8-page resume. It's not possible for someone with four years of experience to need 8 pages to discuss his or her experience.
Remember Strunk and White's injunction to “omit needless words.” (Rule 17 in Elements of Style)
