You should be creative, bold and humorous in your Cover Letter, but always be yourself. Nothing impresses an employer more than your knowledge of them or the company. Try and key in on something that will make your cover letter stand out; find some pertinent information about the company. Of course you only want to focus on the positive. Employers use the resume process to narrow their selection. They will choose the best of the best as perceived by what is in your resume. Your resume is your only initial sales tool to impress the employer enough to give you an interview. As the bad clich� goes � You can only make a first impression once.
It's important that your resume be as strong and positive as possible. A poorly organized and haphazardly written resume demonstrates to the employer that you are not serious about yourself, and if you are not serious about yourself, you are probably not going to be an asset to the company.
