If your resume will be read by a resume scanning program for key words, it's absolutely imperative that those key words be included in your text. Consequently, tailoring your resume to an ad, networking recommendation or job description is probably even more important than if a person were doing the initial screening. In this respect people-scanned and computer-scanned resumes are very similar. However, because some computer scanners have difficulty reading vertical lines, italics and unusual type fonts, techniques you might use to grab the attention of recruiters can be misinterpreted by a computer. If your resume is likely to be scanned, keep the format simple and use only boldface type and bullets to highlight major points.

It is extremely unlikely that anyone coming out of school with a technical degree will go into one area and stay there. Today's students have to look forward to the excitement of probably having three or four careers.

A resume is an important tool, but it can't get you a job. Only people can do that. If you want your job search to be successful, concentrate on people and prepare your resume to suit their needs.
