A cover letter should
be brief and to the point. It should be no longer than one page -
perhaps 3 or 4 paragraphs - and should include your signature.
Recruiters are pressed for time and often only have time to skim through
applications. Use statistics, highlighted statements, or bullets to
make sure that vital information can be easily spotted.
Make sure that the messaging in your letter is consistent with the
information included in your resume. Your cover letter should not be a
laundry list of items from your resume. Instead, highlight skills and
experiences that are most relevant to the job opening and provide
concrete examples of the skills, training, and/or experiences that are
the basis for your confidence.
