How to write a good cover letter to go with a CV and what should you include, is a question most of us have asked at some point.  Very often an advert will say if you should send a covering letter with your application although some bigger firms have a set application form for you to complete and do cover letter, so always be sure to check this first. Your covering letter is a chance for you to give the company you are applying to an overview of why you think you would be suitable for the position offered and should highlight the main reasons that you would like to apply and why you feel you would be suited.
In contrast to a CV, a cover letter should be short and sweet and to the point. It is usually three or four paragraphs and should give the employer an overview of who you are and your key skills. I always think that a CV should be broken down in to three sections. The opening paragraph should commence with an introduction to who you are and explain your current situation. The middle paragraph should mention your qualifications and brief employment history and the last paragraph should talk about why you think you would be suitable for then job.
