While it is not as long, a cover letter requires the same attention as preparing a curriculum vitae or resume.
The role of your cover letter is to ensure your resume gets read. Job applications are scanned in seconds by a human eye or a piece of software. In both cases the reader is looking to see if your skills and experience match the criteria detailed in a job ad.
Your first step in writing a cover letter should be to go through the job ad and underline the key words used by the employer/recruiter. As long as you can back up your claims, try to use these words in your cover letter.
A cover letter should not regurgitate your CV. It should zero why you are a good match for the job role in just three or four paragraphs.
It’s also vital that your cover letter is tailored to each job you’re going for. If at all possible, personalise the letter using the relevant manager or recruitment consultant’s name. Place the name of recipient, their title, company name and address in the left hand corner.
Employers/recruiters hate to receive a formula letter – particularly when the applicant has forgotten to change the name from the last employer they applied to so triple check these details.
Use simple language and the same font and style as your resume. The experts recommend using a font that is easy to read such as 11 point Arial as well as A4 white paper for hard copies of your cover letter.
