A functional resume emphasises your skills and abilities, or ‘functional areas’, rather than chronological employment history and is especially useful when you are changing your career focus, when you have had gaps in your employment, or when you want to highlight your skills and achievements from older jobs, or from volunteer or extracurricular experience. The functional resume is all about relevance, enabling you to focus on what is most important for a particular position, so it should be tailored for each job application.
Alternatively, you may want to consider using a more traditional reverse chronological resume or one-page career summary. View summaries of the benefits of each resume template.
