One of the first misconceptions that people hold about the use of resumes is that they are never actually read, especially when there are online application forms to be filled out. While this cannot be proven either way, I do know from my own experience as a professional writer that most recruiters do look at the resumes received because it provides a general overview of the candidate's attention to, or lack thereof, details such as the style and type of writing.
Work Experience -- in this section you give a one paragraph summary for each of your previous jobs. This should include starting and ending date, reason for leaving, job title and duties, and any special accomplishments for each of the jobs. Education -- gives a summary of all schools attended, degrees earned, and special seminars or training courses that you have attended. Honors and Awards -- it's a good idea to list any special awards you have received. Personal -- information about your hobbies and activities should be included. Others -- professional organizations that you belong to, computer or programming skills, articles or books published. References -- you can state something like, "references available upon request," or list at least 3 on your resume. It's important to include all of the basic information on your resume.
Other misconceptions include the use of an objective on the resume and writing detailed job descriptions. A job objective is usually a statement of what the candidate would like to do or the specific job they are seeking. The reason why this is not needed is that the cover letter should express interest in the position and there is no need to state it again. In addition, many objective statements are so specific that the candidate would be ruled out from other potential positions that may be related to the advertised job. In addition, many jobs I have seen listed on resumes includes wording that either came from job descriptions or have been written like standard wording from these types of descriptions, and that doesn't necessarily explain the skills the candidate has and may contain jargon that is not easily understood by everyone reading it.
Those questions represent the most common reasons why someone would begin to look at their resume and decide if it needs to be updated. What most people discover over time is that their resume should always be update-to-date as job changes can occur suddenly and without any prior warning.
