NEVER use expressions like “Duties included,” “Responsibilities included,” or “Responsible for.” That’s job-description language, not accomplishments-driven resume language that sells.
Instead, emphasize the special things you did to set yourself apart and do the job better than anyone else.
Finally, a word of caution: Resist the temptation to blow your accomplishments out of proportion. Accomplishments should be measurable whenever possible and always verifiable. Don’t risk having a prospective employer call a former supervisor and ask, “Did she really save the company from bankruptcy?” and have your ex-boss say, “Huh?”
