Check spelling and grammatical errors: Even the smallest spelling or grammatical error may become the reason that eliminates your name out of the list of potential candidates. So, do not forget to check carefully for any error before clicking the send button, or bringing the resume across a long way to the employer.
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.
