1. Too many technical skills listed. Try listing your top 5 skills that you can answer  any question in depth. You might know every version of a technical skill but list the latest version you are proficient .
2. 2 Grammar and typos. So many ways to avoid besides a spell check. This alone presents you as sloppy with no attention to detail.  You will be placed in the bad job candidate pile.
   3 Too general or too many pages. Try specific job accomplishments at each job you have held. And try to limit to 1-2 pages maximum.

Seems simple enough. But most resumes I reviewed had one or more of these mistakes. Very rare to place those job candidates at the top of the hiring  list.
