Common Cover Letter Mistakes That Get You Rejected

5 min read

Myth: recruiters read every cover letter like a novel. Reality: many read paragraph one, then jump to the resume if the letter adds nothing new.

You're not writing to impress a writing coach. You're writing so a tired screener knows which bullet to trust. If the letter doesn't do that, it won't save a weak resume and it can sink a strong one.

Check your resume for free so the letter points at bullets that actually parse for this posting.

Then open the questions below. Each one maps to a rejection pattern we see in Greenhouse and Workday optional letter fields.

You don't need a new degree to fix this. You need ten quiet minutes with the posting open beside your draft. That's enough to catch the mistakes that actually cost interviews.

What is a cover letter supposed to do in a portal upload?

The resume proves scope. The letter explains why this role, why now, and which bullet to read first. That's it.

Letters fail when they try to be a second resume. Parsers already stored your jobs. Humans want a signpost, not a recap.

Before: Four paragraphs restating every job title from the PDF.

After: Two sentences naming one posting duty and one bullet that proves it.

Optional fields tempt shortcuts. Don't paste a template you used yesterday without swapping company names. That mistake ends more screens than a missing Oxford comma.

Common cover letter mistakes that get you rejected: questions worth answering tonight

Does repeating your resume count as a mistake?

Yes. If paragraph two lists the same bullets in prose, the reader assumes you had nothing else to say. Use the letter for context the resume cannot carry: why you left, why this stack, why this team size.

Before: "At Acme I managed email campaigns, social posts, and reporting."

After: "Acme's lifecycle program lived in Klaviyo; your posting asks for the same tool on a larger catalog, which matches my last role's 40-SKU rollout."

Why is the wrong company name still so common?

Batch apply habits. You duplicate a file, change the greeting, and miss one body reference. Some portals also autofill an old upload. Run a final search for the last three employers you applied to.

I've closed cover tabs in Workday when paragraph three still praised a competitor we do not partner with. The resume might have been fine. The letter told me the candidate was not paying attention.

Are empty enthusiasm lines a rejection risk?

They are. "Thrilled," "dream role," and "perfect fit" without a fact read like spam. Tie enthusiasm to work you already did that mirrors line one of the job description.

Before: "I would be honored to join your world-class team."

After: "Your req lists NetSuite vendor onboarding; I processed 120 vendor records per quarter in my last finance internship."

Should you apologize for gaps or short jobs in the letter?

Usually no in paragraph one. Lead with current skill. If the gap is long and visible, one honest sentence in paragraph two beats a defensive essay. Save detail for the interview if asked.

Does length alone get you rejected?

Long letters get skimmed, not auto-rejected. The risk is burying your proof line on page two. One page with three tight paragraphs beats two pages of company history copied from the About page.

What about AI-drafted letters?

Generic AI output fails the same tests as generic templates. If you use a draft tool, swap every sentence that could fit another employer. Keep the structure, replace the nouns with ones from this posting.

Copy-paste opening you can adapt per posting:

Dear [Name or Hiring Team],
Your [title] posting emphasizes [noun from line 1 of the job description].
In my role at [employer on resume], I [past-tense verb + scope/metric matching that noun].

Fast rejection triggers beyond spelling

• Attachments when the portal wants plain text in a box.
• Creative fonts that do not match the resume PDF.
• Salary demands when the posting never asked.
• Negative lines about a prior boss, even if true.
• Claims of skills that do not appear in experience bullets.
• Headers that repeat your address block and eat the character limit.

Before: Letter argues you're a fast learner with no example attached.

After: Letter cites one project with dates that match the resume row.

Generic tone traps are covered in why generic cover letters get skipped . Fix specificity before you debate semicolons.

Align the letter with a parsed resume

Highlight three must-have nouns in the posting. Search your resume PDF plain-text export for each. If one is missing, fix the resume before you polish adjectives in the letter.

Generate a cover letter from the same posting text, then replace the opening with your proof sentence only.

Score your job match to see which required terms still sit outside dated bullets.

Proof beats performance

Common cover letter mistakes that get you rejected cluster around laziness signals: wrong names, resume repeats, and praise without evidence. You don't need a new template. You need one posting noun and one scoped result in paragraph one.

Job search pressure makes every field feel urgent. Spend ten minutes on the letter only after the resume dates and bullets match the req. Then send. You can always follow up. You cannot unsend a letter that names the wrong company.
