If I am recruiting for a position with your background, there is a good chance that I know what you do at your job, and what you have done at your last job. Rehashing every bullet point from your job description is not going to set you apart on your resume. Providing no more than 5 bullet points on how you have helped the company and set yourself apart from your colleagues is a much stronger way to present your background. Please don't bury me under 25 bullet points, including "Other duties as assigned", and expect me to have any interest in what you have written. Highlight how you have saved money for the company, a special project you implemented, or how you successfully improved customer service feedback. Give me a reason to see value in hiring you.
Similarly, in a cover letter, please do not add a laundry list of qualifications ("I am personable, dependable, professional, reliable...") I don't want your qualification grocery list! I want an idea of what you can do. You are able to share this through colorful examples of your success. Share what accolades your boss has shared about you. Give some information about what you have done that will set you apart from the sea of other candidates.
In an interview, share examples as well. Make sure they are examples with positive outcomes!!! You bring more of your personality with examples! I have said it over and over and will say it again: PEOPLE HIRE WHO THEY LIKE!
