A CV, or curriculum vitae, serves as a personal marketing tool to secure job interviews rather than jobs, and should succinctly detail relevant education and experience while considering employer preferences. It's essential to maintain professionalism in structure and content, avoiding errors and irrelevant information, with a clear focus on achievements that align with job specifications. Additionally, the importance of a killer cover letter is highlighted as it significantly influences first impressions and should effectively outline interest and qualifications for the desired position.
