The term Curriculum Vitae (CV) literally translates to “the course of your life” from Latin. And that pretty much sums up what it should consist of.
A CV is supposed to go through your whole life, your whole work history, education, academic accomplishments, research, any publications that have your name on them, and anything else you have done in your professional life.
If employers expect more candidates for a given position, they may ask for a CV summary. That is a shortened version of your CV, typically 2-3 pages long, that helps them pre-select candidates before they see your full CV.
And one last thing – if you are applying for a job in Europe, you should know that there the term CV is used for what is called a resume in the USA. So feel free to just rename your resume file to “[Name] CV” and you should be good to go.
