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.

Tailor both the resume and cover letter. How many times have you heard people say they customize their cover letter, but send the same resume to everyone? Usually they are very proud of themselves for doing this, as many job seekers send one form letter and resume to everyone. Unfortunately, when a resume is competing with 200 to 400 others, it has to stand out from the crowd. Recruiters don't have time to separate the "diamonds from the dirt" in the 10 to 60 seconds they spend skimming for relevant experience. It is the candidate's responsibility to sort the valuable stuff from the extraneous, using only 20-carat material to land an interview.

Beware of all enterprises that require new clothes.
