When detailing prior positions and accomplishments, use dates to show how your job responsibilities have grown and changed over time. For example, instead of saying “I worked as a sales associate for the company, then as an assistant sales manager” say “From 1/2004 to 6/2006 I worked as a sales associate and on 6/2006 I was promoted to assistant sales manager.” Showing advancement and direction in your career is a great way to communicate that you are qualified and ready for a promotion.
