Cover Letter Mistakes To Avoid In 2026

The most common mistake is restating the resume in paragraph form. If a sentence just repeats a bullet point from your resume, cut it — the letter should add context the resume can't hold.

A close second: generic enthusiasm that could apply to any company. "I'm excited about this opportunity" says nothing on its own; naming a specific product, initiative, or challenge shows you actually did the research.

Overexplaining a career gap or transition is another common trap. A sentence of honest context is usually enough — a full paragraph defending it tends to draw more attention to it than it deserves.

Watch your closing line too. "I look forward to hearing from you" is fine but forgettable — a line that references a concrete next step reads as more confident.

Finally, resist the temptation to use the same letter for every application with only the company name swapped. Hiring managers can usually tell, and it undercuts the one thing a cover letter is supposed to prove: that you actually want this job, not just a job.
