I don't know if I could seriously get my resume under one page. Right now my resume is just 2 full pages; not really sure what I could cut out.
BTW, I've also heard conflicting points on the one page thing (a lot of people say 2 is OK, more if you have a ton of stuff to put on there.) I know admissions staffers don't have a lot of time and probably only spend <1 minute on the resume, so 1 page would make sense, but at the expense of cutting relevant info? Where else on the app would that stuff go? What do you guys put on there, just academic stuff?
