Strong action verbs and tangible results in customer support
The first bullet of each section has a strong action verb accompanied by a measurable outcome, i.e. “exceeded sales target by 18%”, “achieved a 100% customer approval”, and “greeted 100+ daily guests”. These bullets clearly communicate that the applicant is not only well-versed in customer service, but that they can deliver results that are beneficial to the company. You should include as many numerical examples like these as you can, since hiring managers often skim resumes for such measures of proof.
