Cover letters remain a critical component of job applications, yet many candidates make the same mistakes repeatedly. Understanding these common pitfalls can dramatically improve your application success rate.

The first major mistake is using generic, one-size-fits-all cover letters. Employers can immediately tell when you've sent the same letter to dozens of companies. This approach shows a lack of genuine interest and effort.

Another critical error is simply restating your resume. Your cover letter should complement your resume, not duplicate it. Use this space to tell a story about your career journey and explain why you're passionate about the specific role and company.

Many candidates also fail to research the company properly. A cover letter that doesn't reference the company's values, recent news, or specific challenges shows you haven't done your homework.

Poor formatting and typos are instant deal-breakers. Even the most qualified candidate can be eliminated due to sloppy presentation. Always proofread multiple times and consider having someone else review your letter.

Finally, many cover letters lack a clear call to action. Don't just end with "I look forward to hearing from you." Be specific about next steps and show enthusiasm for moving forward in the process.
