The strength of your resume depends on your confidence, but confidence here does not mean arrogance. Your resume must absolutely avoid words and phrases that may make the readers think that you are too sharp and even deceitful. Use the resume and resume to make the readers understand that you are sensitive, professional, politely and well qualified.
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.
