The difference between a CV and a resume lies in the length, layout, and purpose of these documents. CVs have no length limit; resumes are typically one to two pages long.
A CV details the whole course of the candidate’s academic career; a resume summarizes skills and work experience.
The resume will be tailored to each position whereas the CV will stay put and any changes will be in the cover letter.
The main difference between a resume and a CV is that a CV is intended to be a full record of your career history and a resume is a brief, targeted list of skills and achievements.
