Body of Cover Letter
The body of your cover letter lets the employer know what position you are applying for, why the employer should select you for an interview, and how you will follow-up.
The first paragraph of your letter should include information on why you are writing. Mention the position you are applying for and where you found the job listing. Include the name of a mutual contact, if you have one.
The next section of your cover letter should describe what you have to offer the employer. Mention specifically how your qualifications match the job you are applying for. Remember, you are interpreting your CV, not repeating it.
Conclude your cover letter by thanking the employer for considering you for the position. Include information on how you will follow-up.
Yours sincerely if you have their name, yours faithfully if not.
