Yes! A cover letter should be short and to the point. Should contain:
Names
A successful candidate for a job opening takes the time to find out the names of the key people in the organization where they are applying. Addressing your letter to the specific person you will be interviewing with is beneficial and important. No one wants to receive a letter addressed to Dear Sir or Madame. The salutation is your chance to make a personal connection with the employer.
Specific Job
The cover letter is the place where the potential employee should mention what job in particular they are applying for. A successful cover letter tells the employer at a quick glance exactly what sort of work the candidate is seeking and enables her to make a quick decision whether to keep reading or not.
Job Requirements
A cover letter should show the employer that you have the qualifications to perform the job you are applying for. This portion of the letter should address the job requirements and how you will perform them better than someone else. This is where the job candidate sells himself and his qualifications to the employer.
Closing
The closing of a cover letter is where you should sum up why you are the perfect person for this job. Then ask the employer for an interview. It is important that a cover letter accurately expresses your abilities; this is not the place to exaggerate. The cover letter is finished off with a closing salutation such as, "Thank you for your time," or "Sincerely," and your name. Sign the cover letter in ink, just above your typed name.
