The words mean different things in different places, and remote hiring crosses all of them.
The regional split
- US and Canada: résumé is the short document; CV is academic and long
- UK, Ireland, India, most of Europe: CV is the short document
- Academia everywhere: CV means the full publication record
What to actually send
For any non-academic remote job, send a one or two page document. Name the file with your own name and the word the ad used. Nobody has ever been rejected for the filename, but matching it removes a small friction.
The one real difference to observe
Some regions expect a photo, date of birth or marital status on a CV. Most English-speaking employers do not want any of them, and including them can create legal awkwardness. Leave them off unless the ad asks.
Common questions
Should I put a photo on my CV?
Not for US, UK, Irish or most remote-international applications. Some European and Middle Eastern employers still expect one.
Is a CV longer than a résumé?
Only in the US sense, where CV means an academic document. Elsewhere they are the same thing.
