The openers to delete
- Responsible for — describes the assignment, not the outcome.
- Duties included — a job description in disguise.
- Assisted with, helped with — minimises your own contribution.
- Worked on — says nothing at all.
- Tasked with — passive, and implies you may not have finished.
By what you actually did
Built something: designed, developed, built, launched, implemented, established, created.
Improved something: cut, reduced, raised, accelerated, streamlined, optimised, rebuilt.
Led people: led, managed, mentored, trained, coordinated, supervised, coached.
Analysed something: analysed, identified, diagnosed, evaluated, forecast, modelled.
Persuaded someone: negotiated, presented, secured, influenced, closed, won.
One verb per bullet
Start with the verb, in past tense for previous roles and present for your current one. Do not stack three verbs — led, managed, and oversaw is one action described three times.
The verb is not the point
A strong verb attached to nothing measurable is still a weak bullet. Spearheaded a strategic initiative is a thesaurus exercise. The verb should introduce a result, not replace one.
