+a million. The only reason for a resume to be longer than one page is if you are applying for an academic position and need to list your publications. I've read that the amount of time spent looking at a resume is extremely low, somewhere in the neighborhood of 30 seconds.
Depending on your field, this is insanely wrong. Any technical field if you've had more than one job it's almost impossible to fit to one page unless work = your life. HR filters by keywords like no other. And managers actually like to see what you've done at other jobs.
