Are you looking for a job? Or do you plan to look for a job in the near future?
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. But most people wait until a resume is needed and it is at this time that a decision is made to try to refine and update it, or leave it as is and hope that it will be sufficient enough to gain a recruiter or hiring manager's attention. There is a misconception that because resumes are rarely mailed out any longer, they are not that important. Yet many online application forms still request that a resume copy be uploaded for review.
