Every great CV requires a great cover letter
Cover letters are a critical part of the job application process.
Its purpose is to introduce you to the employer as a strong candidate and briefly illustrate how your skill and experience match those needed to do the job.
If you are wondering if you should include a cover letter with your CV or application, the answer is ‘yes’, unless it has been specifically stated in the application instructions that one should not be included. A well-written cover letter gives you the chance to sell yourself to the employer in a narrative format, as opposed to a formal CV, and affords you the opportunity to highlight your strongest qualifications. It will also make clear why you are interested in the job and the organisation.
