A CV is an in-depth document that is typically over two pages and contains a high level of detail about one's education, accomplishments, publications, awards, and full career history. It is organized chronologically and does not change for different positions. A resume is a concise one-page document that highlights one's relevant skills and experience for a particular position. It is tailored for each job application and does not need to include one's entire career history or be in chronological order. The main differences between a CV and resume are length, purpose, and level of customization.
