Tips for Using Them

Choose verbs that match the specific outcome you achieved rather than the general action you took to ensure your resume highlights results over tasks. Quantify your success whenever possible by adding numbers or percentages to your bullet points, as this provides concrete evidence of your effectiveness. Always tailor your word selection to the job description by matching the language used by the hiring manager in the posting. Avoid using the same verb in every bullet point to maintain reader interest and demonstrate a diverse range of skills.
