The resume that lands you the job interview isnt a simple listing of your past duties or work experience. It has to convince readers that you have the required skills and abilities to exceed the expectations of the position so your resume should be structured in a way that arouses employers interest in you and gives them reasons as to why you are more qualified than others while encouraging the employer to get in touch with you for an interview.
Functional resumes are good when you have little to zero work experience (or new grads). This type of resume allows you to showcase skills that fit in with the job requirements. Fair warning: most recruiters and hiring managers dont like this format and feel as though you may be hiding something. If you have a chronological resume you do not want to have one part chronological and one part functional because it will throw off the entire formatting and may confuse the employer about your skill set.
Whether youre still using an objective statement or you havent incorporated the use of searchable keywords using a current resume writing style is essential in todays competitive job search.
