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).
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.
