Some great tips on how to still have a good resume without having had much job experience. I still believe other experiences can be listed besides jobs (see other posts) but nonetheless this serves as a great guide. With computer science and social media skills (only when you've used them in non-personal ways, blogging, marketing, etc) boosting a resume, skills just from day to day life, a young resume can still be strong.
