Resume Updating? Watch Out!
Why do you need to watch out? Quickly stated, the reason is that old news may not fit a new day. Adding your current or most recent job before earlier employments may give you the sense that you have completed the updating task. Stopping at this point, though, may undermine your chances to be a good fit to the job you now seek. A better approach is to back up and first research the key words used in job postings as well as identify industry changes, and observe job trends. Then adjust your descriptions and bullet points in your earlier employments also.
