Covering Letter
A cover letter is your introduction to a potential new employer and so it is vital that it not only gives the right impression but that it grabs their attention and entices them to read your CV.

When structuring the letter, there is a simple formula to follow:

First paragraph
Explain your reason for writing and, if this is a targeted letter, where you saw the advertisement. You should then grab the reader’s attention by including a few lines about what you have to offer, ensuring this is directly relevant to the specific role (targeted) or type of role (speculative) that you are applying for.

The next two paragraphs 
Focus on your skills, experiences and achievements. In the case of a targeted letter, it is important to demonstrate how you meet the essential criteria specified in the advertisement. If this is a speculative application, think about what skills are looked for in the type of role you are targeting and make these the focus of the two paragraphs.

A cover letter should also include something directly related to the company that you are writing to. It is a good idea to state what it is about their organisation that interests you and, if you can include any statistics or snippets of information, that indicate that you have done some research, this can only improve your chances.
End the letter on a positive note. Thank them for their time and consideration and proactively encourage an interview, stressing your flexibility with regard to interview dates and times.

In summary, your cover letter should pick out the very best bits of your CV, without just repeating the information verbatim. It should convey a positive approach and attitude and should grab the reader’s attention.
