Cover Letter Mistakes That Get You Rejected

A weak cover letter does not just fail to help. It can talk a strong resume out of the interview pile.

Quick answer

Avoid these: generic openings, resume copy-paste, fake passion, wrong company name, unedited AI tone, and optional letters that add nothing. Fix structure with how to write a cover letter.

Mistake 1: The dead opening

"I am writing to express my interest" wastes the skim. Replace with role + proof.

Mistake 2: Resume in paragraph form

If every sentence restates a bullet, delete the letter or rewrite for context only.

Mistake 3: Fake specificity

"I love your innovative culture" with zero product or problem mention.

Mistake 4: Wrong name or company

Mail-merge errors are instant rejects. Search-replace carefully.

Mistake 5: Unedited AI

Identical rhythm, empty adjectives, and skills you cannot discuss. Humanize with AI cover letter that sounds human.

Mistake 6: Writing when you should skip

Optional field + zero time = skip. Bad optional letters signal poor judgment.
