When you choose the font, style (bold, italic etc.) or point size for a given type of information, such as job dates, stick to it. Make sure if one section heading is Arial 12 pt bold, all section headings are Arial 12 pt bold and that none of them is underlined or italic. If the dates under Education are 11 pt, make sure that under Employment they are not 10 pt. If one entry has a bullet point, put bullet points on all. If you use paragraph spacing, make sure that you have the same space after or before each paragraph of the same type.
