Also, do not forget that the content of the resume and it must not be different in information, especially important ones. However, it is neither a part nor a summary of your one. So, differentiate the it is function and resume.
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.
