Only 1% of  resumes that pass through a hiring managers hands grab their attention.  The 15-30 seconds scanning time mentioned by some is bunk! You need to approach the way you write a resume to be in that 1%.   Your resume needs to do only two things:

1. - 1st grab the reader’s attention in milliseconds, and
2. - 2nd give them sufficient rich content to make them call you.

Fail to achieve those 2 fatal requirements and your resume will be recycled.
