“Dear Sir or Madam” is one of the worst mistakes in cover letters. Cover letters that are too long can seem lengthy and cause the reader to lose interest.

The cover letter should not be longer than one page - applicants should limit themselves to the essential information. Avoid overestimating your skills and avoid vague or exaggerated statements. It's important to note that the importance of a cover letter can vary from company to company and industry to industry. It is advisable to consider the specific requirements of the position and company in order to make an informed decision.
