Never underestimate the power of a great covering letter and never submit a job application without one. Your cover letter is an invitation to an employer to look through your CV, and consider you for a role with their organisation. It should be clear, concise, customised to the organisation you are looking to work for and it should make a compelling case as to why you are the best person for the job.
