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.
Ultimately, you want to try to strike a balance between including experience that is both timely and relevant. There are several basic types of resumes used to apply for job openings. Before you spend time writing up all the details around each position you’ve had, you should decide what style of resume to use, as that can affect how you describe, organize, and list your experience, education, skills, qualifications, and other credentials for employment.
