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.
