Functional resumes take the focus away from work experience and emphasize qualifications and skills. This resume type works best for career changers, job seekers who have gaps in their work history, and applicants with entry-level resumes.
A resume is the representation of your professional self. It is a concise compilation of your educational and professional experience, as well as the skills that make you desirable for the workforce. It is what you use to sell your merit and skills to potential employers.
