Highlight key points. Emphasize important terms or position titles by using capital letters, quotation marks, bullets, or even asterisks. Do not use italics, underline, or bold because these normally gets lost in an electronic resume. Give a summary of your work experience. Do not rely on the position title alone to describe your job experience.
Different companies define certain position differently.
Try to use a lot of keywords, as this will be to your advantage in resume search databases. Electronic resumes are usually lengthier than the traditional 1-page printed resumes, but you should still keep it under three pages. Use common section headings. Use section headings that everyone is familiar with. Choose numbers over words.
