Ah, I didn't realize all CVs are longer. Yeah, a résumé longer than a page is considered bad practice.
However, as an American, I've never heard of a résumé including a mission statement or being adjusted per job. As you said, they're very short documents. I've always seen them just giving the same factual history of the person's employment/education, and the person similarly attaches a cover letter tailored to the specific job, repeating some highlights and how it qualifies him and saying how perfect this job is for him.
* CVs are generally longer - 2-4 sides. Resumes are more of a one page and done thing.
* Resumes often include a mission statement or similar. CVs don't - you'd put that stuff on a 'cover letter', if at all
* CVs are generally not adjusted per job - it's everything, with only the older stuff abbreviated. Whereas resumes are tailored.
