Neatness counts, so be sure it's easy for prospective employers to find what they are looking for. Don't be afraid to modify CV categories so that they best reflect your own skills and experience. Blank spaces avoid blank stares, so separate the sections of your CV with well-utilized blank space, rather than cramming everything too tightly together. It's not unheard of for CV pages to get separated from one another, so be sure that you include your name on every page. Keep it simple, stupid.
Paper makes the cut.
Use good white paper and get a clean, good quality laser print. The easier you can make it to read your CV, the more attention it will get. The Job Search Series workshop on creating a CV offered practical advice and useful hints for students who need to do so, whether the CV is being sent with a job application or a grant application.
