Should I expect more detail than a single page from a resume?

It’s been said that an executive’s background (what makes him or her right for the position) should be organized for presentation in an elevator speech or a single paragraph. The idea of a resume is not to publish one’s biography, but to obtain an interview. Too much information is worse than too little when it comes to resumes. Most work backgrounds and work accomplishments should be focused to the position applied for and written on a single page. It is acceptable to present a second page listing appropriate credentials, education and other relevant accomplishments.
