I’m wondering if it’s appropriate to staple a 2-page resume?
Do not staple the resume, even if 2 (or more) pages. Without a staple, the two pages can be placed side-by-side to view the whole resume at once. That said, if you have a 2nd page, put your name on top of page 2 (header). By doing this, if the 2 pages are separated they can be easily put back together.
