A good or even perfect resume has all its content short, but dense with information. Only the relevant points that benefit your core argument (e.g. why they should hire you) should be included in your CV.
Use effective action words like prepared, managed, developed, etc.. These words will make your resume stand out. Avoid using the same verb over and over, as not to make your resume look repetitive or too generic. Use efficient word choices to clear up space. Get rid of over-flowering adverbs and/or adjective. Lastly, be positive and don’t include negative aspects of yourself that won’t really affect your performance in the work place.
