Just like a CV a good cover letter is very important when you are looking for work.
With this in mind, you have to make sure that your cover letter makes enough of an impression in those to make the reader want to learn more about you. But what should it contain?
Building upon the information in your CV, a cover letter should state in no uncertain terms why this company should hire you. Everything it includes should encourage the recruiter to give your CV the attention it deserves.
