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.
Some companies will indicate that they want you to submit a CV rather than a resume. A CV and a resume are not the same. CV stands for “curriculum vitae” and is meant to be an expansion of your resume. It is much longer than a resume, often three pages or more, and focuses mainly on your academic and professional accomplishments, with a particular focus on education.
