Vivian Giang from Business Insider has some great tips to ensure that your resume gets through to a live human being:
Do not place your contact information in the header of your resume, because filtering softwares can be set to ignore headers and footers so there is a risk this information will be deleted.
Choose a conservative font such as Verdana, Arial, Tahoma, or Calibri. Gillis says that serif fonts, such as Times Roman or Cambria may be rejected by screening software.
Do not use any script fonts.
The smallest font size to use for the body of your resume should be 11 point. “Any smaller and you’re probably asking for trouble.”
No graphics or logos.
Do not format using tables.
A one-inch margin top and bottom is best.
Do not use any lines that cross the entire page from margin to margin, because “some filters have been created that will reject a document for nothing more than having a single line run continuously across the page,” he writes.
