Resume - Your calling card

The resume needs to be as long as it needs to be - and no longer. The days of a one page resume have long ended. There is a myth that a short resume is more likely to be read, and that is incorrect. Today people are changing jobs more and more frequently, necessitating longer resumes. So take the space needed to tell your story. Do what is appropriate at your level. Generally speaking, the more senior the individual, the longer the resume.
You decide whether to put something in the resume by asking the following question: does it help my case? If so, put it in; if not, leave it out.
