Although most formatting such as bold, italics and underlining is lost in an electronic resume, you may use capital letters, quotation marks, even asterisks, to emphasize important words or section titles. While electronic resumes may exceed the traditional one to two page limit of paper resumes, in most cases, it should not exceed three pages. List only recent information. The general rule of thumb is to show your work experience only for the last 10 to 15 years. Quantify your experience.
Numbers are a powerful tool.
Be organized, logical and concise. In addition to reviewing your experience, employers also use the resume to get a sense of whether you are organized, logical and concise. Abandon the use of exorbitant, exquisite vocabulary. In other words, don't try to impress employers with the depth of your vocabulary. Use words everyone can understand.
