Your cover letter is an excellent opportunity to communicate your personality, enthusiasm and professional strengths to an employer. While there is a standard format for a cover letter, it is important to make your cover letter distinctive and personal; do not be afraid to think outside the box. Go into detail about your background and skills instead of reiterating what is already on your resume. Keep in mind that your letter gives the employer a sample of how well you write. Be careful about typos, spell-check your letter, and edit any grammatical mistakes.
