One purpose of a cover letter is to enhance your job application in the hopes of getting an interview. In addition to sending in your resume, many companies will require you to submit a cover letter as part of the job application. A cover letter is a one-page document that introduces yourself to potential employers and highlights your key accomplishments. Please note: The cover letter is not a summary of your resume! You should refer back to your resume but do not simply restate the information that is already available from the resume. That would not add any value and would defeat the purpose of having a cover letter. Instead, the cover letter should complement your resume by drawing attention to your strengths and presenting relevant information not available on your resume.
The cover letter should communicate to the employer the reason why you are writing, your interest and skills in the specific field, your achievements, and why you are a good match for the company and the position. There are 4 types of cover letters and it is important to customize your cover letter to each job you apply for. Companies act more positively when you show them you took the time and effort instead of sending a generic letter that you send to every company. Thus, it is important to take the time to write an effective cover letter and proofread it carefully before sending it out. A poorly written cover letter may cause your whole application to be thrown out!
There are many reasons why cover letters are important. The purpose of a cover letter is to be able to make a difference with your application and be a deciding factor between you and your closest competitor.
