When it comes to applying for a new job, there are several components that need to be in place. Before you head in for your first interview, you will be required to fill out a job application. The job application will require you to include pieces of information about yourself and then a resume will be requested. After the resume, some applications will ask for a cover letter. Even if the letter isn’t required, it can help catch the eye of your potential employer as they look through applications. While many know what a resume is, some may not be clear as to what a cover letter is or what it should include.
