It's important to prioritize the content of your resume so that your most important and relevant experience is listed first, with key accomplishments listed at the top of each position. As you compile the information for your resume, prioritize your accomplishments by importance, achievements, and relevance to the job you're applying for.
Decide What's Relevant
How do you decide what's relevant? Put yourself in a potential employer's position - will the information on your resume help convince the employer that you are a worthwhile candidate to interview for the position they are trying to fill?
Prioritize the Details
Next, prioritize the information you provide in each description. Present what you think is of greatest interest to your potential employer first. For instance, consider a candidate seeking a job in interior design. The resume might reflect a retail experience in which 80% of the candidate's time was spent on the sales floor, and 20% was spent designing window and floor displays. Priority, determined by relevance to the employer, dictates that design of window and floor displays should be listed before sales.
In addition, quantify as much information as you can - numbers, dollar signs, percentages can all help to make your case for getting selected to interview.
