Remember, anyone can say they have customer service skills. You need to prove that you really have those skills. The best way to do this is to showcase what results you’ve achieved with your customer service skills. For example, saying, “Prioritizing customers with an angry tone of voice helped us cut down on negative outbursts in the store by 25%” is better than just saying, “I can prioritize customers based on how angry they seem to be.” Additionally, certifications and awards always impress hiring managers and can be a great way to prove your skills.
