I'm helping a friend edit her resume and cover letters and it got me to thinking. I'm an attorney, and all through law school we were told that your resume cannot be longer than a page. We even had people tell us "We throw away the second page and don't look at it."
My friend's is two full pages, and she only has two years of post-college job experience. I know it's different if you have decades of experience/many post-grad degrees/lots of publications, but is this one-page rule really a thing in other industries/geographic locations?
