Our job titles don’t always reflect what we really do. So how do you make a career move — either to a new job or maybe to an entirely new field — if you’re worried that your current title might give a hiring manager the wrong idea? The key is to showcase how your skills and experience are relevant to the new job. Start by making a list of the five or six most important responsibilities in the job posting, and jot down your accomplishments in those areas. Based on these notes, write a brief description of yourself that shows you have the experience the new job requires. Add this summary to the top of your résumé — but don’t simply call the section “Summary.” That overused term won’t grab anyone’s attention or distinguish you from other candidates. Instead, give the section a headline that really captures the breadth of your experience.
