A cover letter is a document designed to accompany a CV when presented to an employer. The purpose of a cover letter is to give an opportunity for an applicant to introduce themselves and their credentials.
Most job seekers decide to send their CV without the benefit of a strong CV cover letter, which is a costly mistake. It shows a distinct lack of effort to send a CV bare and will put you at an immediate disadvantage when applying for a job. Employers like to see that you have taken time to analyse the position and formulate some ideas on why you’re the perfect candidate.
Cover letters express your personality and enthusiasm for the position, and provide support for your candidacy that is not covered by your CV. Writing a cover letter can be a challenging and time-consuming task, especially when you must customize it towards each organisation.
