Focus on the most importance: A resume or a resume both requires focusing points. You should go deeply into the most important points about your qualification and knowledge about the job and the company. You may make bold or italic important points (if printing).
Do not expect to win the employer when your resume and resume are common without any particularity. So, do not waste time sending imperfect resume and resume to different employers because your chance of getting to the next round is not significant at all.
