1. Vary up the wording in your bullet points. Dig through your thesaurus (and your brain!) to think of new ways to describe the same task. "Rolled calls" is another way of phrasing "managed heavy phones." Now your resume looks less redundant!
2. Don't list every duty in every section of your resume. Since your resume exists to give employers a summary of your skills, not a play-by-play of everything you’ve ever done, it's okay to leave some skills off one section if they’re less relevant to the job you’re applying for or if you’ve already mentioned them twice. If you limit the number of bullet points you have in each section, you’ll force yourself to diversify across the page.
In addition to spicing up your resume, by following these tips, you'll be making your resume more concise and easier to read, and that will always make a hiring manager happy.
