7. Cover Letter

Attaching a cover letter to your job application is a great way to show employers why you are the perfect fit for their role. It’s made up of 2 to 4 paragraphs and serves as an introduction, allowing you more space and flexibility than what your resume alone can offer.

Cover letters provide recruiters with additional information about who you are as a professional, such as career goals or skills that weren’t included in your resume. Even if it isn’t required by the employer, writing one could be just what sets you apart from other applicants!

Below is an example cover letter:
