A cover letter is a one-page document that is typically submitted alongside a job application, such as a resume or CV. It is a way of introducing yourself to your potential employer and explaining why you are the right fit for the job.
The purpose of a cover letter is to provide additional information that may not be included in your resume or CV, and to demonstrate your enthusiasm and interest in the job.
A well-crafted cover letter can help you make a positive first impression on the employer and increase your chances of being invited for an interview.
