Holbrook says that most American business résumés should be 1 to 3 pages. Entry-level workers and recent grads can probably get by with a single-page, since they have less of a story to tell than their more experienced counterparts. Mid-career workers will probably need 2 pages for their professional histories; a 3rd page, if needed, should be devoted to publications, honors, and continuing education.
Holbrook emphasized that job hunters should be as concerned about the content and quality of their résumés as with their length. The goal of the résumé is to give the hiring manager a clear picture of your professional history. Filling up space with a lot of fluff will probably hurt more than help your case. Likewise, says Holbrook, if your work history is measured in decades rather than years, you probably want to concentrate on the most recent several years and leave out some of the details about your early experience.
A common source of confusion in academic and scientific employment is the difference between a résumé and curriculum vitae, or CV. The CV is a comprehensive description of education, work history, publications, and presentations used for academic hiring. A CV often runs many more pages than the typical business résumé. (An additional source of confusion is the fact that in some European countries "CV" is used to describe a document very similar to what we call a résumé). About a year ago, Science Careers columnist Dave Jensen defined résumé, CV, and a host of other common terms used in job-hunting and career development. In an earlier column, Jensen also described how a CV can be adapted for business use.
