Any friend/colleague who hands me their resume has been.... like really bad at resumes. I think everyone's just bad at resumes. Landscape (wtf?) layout, leaving half a page empty, using colors of any kind (outside of a design role), and using more than a single page early in a career.
For each person's resume I redid, all using my template, they got the callbacks that eventually became their jobs within two weeks.
Biggest single thing you can do: SHORTEN THAT SUCKER.
