Firstly, the resume is a selling document. If you get an interview as a consequence of the person seeing your resume then it has done its job. Secondly, it is a document that you have prepared, not designed and put together by someone else. Therefore, you have ownership and understanding of the content and can explain with confidence any points that need clarification. You will need to change it each time you apply for different positions.
Some people put their effort into the covering letter and then just tack on an old resume.
However, you need to think like a recruitment consultant or employer. Your actual resume document is scanned into the computer and the skills are extracted in the matching process. It is important therefore, that you adopt the following guidelines. The first page of your resume only has the things they must know about you relevant to the job. It is like the Executive Summary in a report.
