A good cover letter
begins with a powerful, clearly written opening paragraph. Your goal is
to briefly describe how you heard about the position and why you're
interested in it. If you're replying to an advertisement mentioning a
code or job number, refer to this in your cover letter as well as any
information specifically requested in the ad that may not be addressed
in your resume such as an availability date or a writing sample.
Your tone should be confident without being arrogant. Avoid attempts to
be "cute" or "catchy" in your opening. Gimmicky attempts to gain
attention can appear insincere. It is best to keep your letter polished
and professional as well as interesting and visually appealing. Mention
only positive things and be formal, yet friendly and open.
