A resume is a 1-2 page document that lists relevant experience and other qualifications for a specific job. It is different from an academic CV in that it focuses on whatever is most important for that industry or company and tends to focus on your ability to perform job duties rather than research or academic accomplishments.
*While general guidelines and examples are helpful, it is recommended that you talk to people in your field search for samples of resumes for the specific job that interests you, as there can be some variation from industry to industry.
