Well, for starters…and certainly most obviously, the length.
Again, just to reiterate, a resume is generally one page long, whereas a CV is as long as you need it to be to thoroughly cover all the information you will be including.
Another way it’s different is how it’s written.
A good resume is specifically targeted (or as we like to say, “tailored”) to the job you’re applying to.
You make sure to highlight the relevant skills and experiences you’ve had that align to the position you’re seeking and try not to include any information that doesn’t relate.
With a CV however, you’re giving the reader a solid overview of all the accomplishments you’ve had in your life.
The quick difference?
