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.
Make sure there are no misspelled words! Mistakes will create the wrong image. Make sure that the punctuation is correct. And make sure that all of your columns line up. See that all of your facts are correct. Don't say you attended 3 years of college, but only show two years worth of grades. Potential employers will note all inaccuracies and wonder why they appear in your resume.
The resume is the first step, your introduction to an employer. First impressions really do count. If you make a poor first impression, you'll never get to step two -- the job interview. To the purpose of your resume is to make a good first impression. In effect, your resume should tell the employer that you have good abilities and are truly interested in working. This report will help you make that good first impression. And it could very well help you to get the better job you're looking for.
Another common misconception is that a resume must be one page in total length. I am not certain I know how that idea became popular or why it has remained so engrained as it ultimately serves little purpose for most candidates and it can work to the detriment of a job seeker. The reason why is that a one page resume, for a person who has fairly extensive experience, can sell them short. This type of resume will either leave off critical information or it will be typed in a font size that is not easy to read.
