I worked a LOT in undergrad - I was a work-study kid, had about 3 internal jobs during the academic year and worked every summer at the school as well.
Some schools seem to care very much about this...Should I "formally" allot space to all my jobs as an undergrad, traditional resume style, or just do a brief list with dates/hours, like so:
College Involvement
- College Mascot
(2004-present)
Make a fool of myself each weekend for our terrible foozball team.
- Work-Study
(2004-2008)
Worked in the following offices through academic years & summers: Financial Aid, Alumni, blah blah.
Hope this makes sense. The latter would take up less space, but doesn't feel very professional to me.
Also, any other "older" applicants with work experience, I'd love to hear how you are approaching the resume!

thanks everyone!
