Write a strong bullet without a percentage
Illustrative before: “Responsible for customer support.” After: “Created a troubleshooting guide for recurring account-access questions and trained incoming support colleagues to use it.” The second version names an output, a problem and an audience without inventing a reduction in ticket volume. You can add frequency, scope or a documented result if you know it. If nobody measured the outcome, describe what changed rather than estimating a convenient percentage.
Keep an evidence note behind each claim
Before shortening a bullet, write down the original situation, your action, the other contributors, the output and how you know the result. A weekly handover checklist can support a claim about documenting a process; it cannot alone support a claim that service speed improved by 40%. Keep private evidence notes outside the submitted resume. Remove confidential customer names or internal figures rather than publishing a source you are not allowed to share.
Begin with the real action
Name what you worked on and what you did. Replace a vague duty such as “responsible for user growth” with the concrete action you took, such as redesigning a new-user activation flow. Then add the method, constraints, and result.
Add scope and constraints
Team size, user volume, budget, time frame, system complexity, and operational limits help readers understand difficulty. Scope is not decoration; it gives the same action a comparable meaning in different environments.
Avoid false precision
Use only figures you can explain and retain their calculation basis. When absolute values are confidential, use year-over-year change, a range, rank, or efficiency improvement. If the outcome is not yet validated, describe the deliverable rather than claiming business impact.
Define your contribution
For cross-functional work, distinguish what you proposed, decided, executed, or coordinated. Saying that you completed work with a team is often more credible than presenting a collective outcome as an individual achievement.
Use interview questions as a final test
For every bullet, ask why the problem mattered, what choice you made, what alternatives existed, and how the result was measured. If you cannot answer one of these questions, add context or use a more accurate claim.
Use claims you can explain and trace. Keyword matching should reveal wording gaps, never manufacture experience.
