What are common mistakes to avoid in a cover letter?

Common pitfalls include being too generic, repeating your CV verbatim, or focusing solely on your needs rather than the employer’s. Avoid typos, overly long paragraphs, or irrelevant details. Instead, keep it concise (half to one page), address the hiring manager by name if possible, and demonstrate how your skills solve the company’s challenges. Proofread multiple times or use tools like grammar checkers for polish.
