The goal of a resume / cover letter are to land an interview. It's not an autobiography. I can say from personal experience that one does not completely read hundreds of resumes. When I was hiring I would get just as much info from a short resume as I would from a long resume. The key difference is that with a shorter more focused resume you have more control over what I actually take away from your resume. So for that reason I use a one page resume that's tightly focused on what I want to do, not everything I've ever been capable of doing. But I don't want my resume in some HR or recruiter database, either. A long resume make work better if you prefer the shotgun approach to finding work...
