Many feel that this style of resume is the most effective, and ImageJOB strongly recommends its use. The functional resume emphasizes your qualifications and abilities in terms of your job titles and responsibilities. This style of resume highlights different areas of employment experience and is arranged with its most significant functions and responsibilities first. Each job title is followed by a brief description of duties and expertise. Dates are not given, or if included, are inconspicuous.
Education is treated in a separate area and, as with the work history, dates are omitted.
I believe, in order to make a functional resume more effective, a concise chronological history, including dates, should be added. Even though the functional resume is a perfect vehicle for describing actual talents and areas of achievement, the omission of dates lessens its effectiveness. A resume without dates is a much weaker resume and could even become a liability. Listing all dates will subtly reassure the reader that nothing has been deleted and that no periods of time have been unaccounted for deliberately or, at best, overlooked. The body of information in this resume is followed and concluded by your personal data.
