Resume writing is the process of creating a document that summarizes a person's work experience, education, skills, and accomplishments. A well-crafted resume is essential for job seekers, as it serves as a marketing tool to showcase qualifications to potential employers. The key components of a resume typically include a contact information section, a summary or objective statement, a detailed list of work experience, education, and relevant skills. Tailoring the resume to match the specific job description can significantly increase the chances of getting noticed by hiring managers.
