What industry are you writing for? There are general guidelines, and there are industry-specific guidelines.
Easy pointers:
- Don't use a generic template. Your resume should stand out but not overly so.
- Keep it to a page, unless you have many years of specialized experience or are quoting your own doctorate research.
- Proofread, proofread, and proofread some more. Have everyone you know proofread your resume and then take it to someone else. Many people in HR are notorious for ditching resumes because of spelling/grammar errors. One of my professors cited the example of an HR rep that would throw out resumes that didn't have "." at the end of every line like they were supposed to.
