A good resume can land you that job interview, so you want to stand out. If formatting a resume isn't your thing, Hloom has 275 free Microsoft Word templates to download.
The templates are spread across different categories, thus catering to different job types. For example, there's an "ATS-optimise" category for templates designed to bypass automatic tracking systems employed by some companies to scan CVs.
All the templates are a standard A4 page or US letter size, and made in Microsoft Office 2010 with the office suite's default fonts. They should also work in OpenOffice and Mac Pages, but not all might retain the formatting.
You can also get free templates on Google Docs, but Word has better formatting options. Of course, this is just the template, so you will still have to write the content to make your CV attractive, using tricks like this formula from Google's HR chief.
