Most cover letter advice focuses on what to add. This one's about what to remove — the specific errors that don't just weaken an application, they end it. Some of these are small and easy to miss right before you hit send, which is exactly why they're worth checking for deliberately.
The wrong company name
This happens more than people admit — reusing a letter and forgetting to update the company name, sometimes leaving a completely different company's name in the opening line. It's one of the fastest ways to get an application dismissed outright, since it's undeniable proof the letter wasn't actually written for this application.
How to avoid it: Before submitting, do one final read specifically checking for the company name and role title — not the whole letter, just those two things, since they're the most common casualties of copy-paste editing.
Typos and grammar errors
A cover letter is, among other things, a writing sample. Errors register as carelessness, and for roles involving communication or attention to detail, they carry extra weight.
How to avoid it: Read it out loud before sending — errors that slide past silent reading often surface immediately when spoken. A second set of eyes helps even more.
Ignoring specific instructions buried in the posting
Some job postings intentionally bury an instruction — like asking you to include a specific word in your letter — as a deliberate filter for candidates who read carefully versus those who skim.
How to avoid it: Read the entire posting, not just the bulleted requirements section. If something unusual is being asked, follow it exactly.
Making it entirely about what you want
A letter focused on salary expectations, growth opportunities, or what the role can do for you — without addressing what you bring to the company — reads as self-interested rather than genuinely engaged.
How to avoid it: Lead with value you offer. Save discussion of what you're looking for, if any, for the very end and keep it brief.
Restating the resume with no new information
A cover letter that just repeats your work history in paragraph form gives the reader nothing they didn't already have. It wastes the one opportunity to add context, personality, or connection that the resume format doesn't allow for.
How to avoid it: Pick one or two things the resume can't fully explain — your motivation, a specific connection to the company, or context around a transition — and focus there instead.
Exaggerating or fabricating a claim
Interviewers frequently ask follow-up questions about specific things mentioned in a cover letter. An exaggerated claim tends to fall apart under a few direct questions, and it damages trust for the rest of the conversation.
How to avoid it: Stick to things you can speak to in detail if asked. Honest and specific beats impressive and shaky every time.
Frequently Asked Questions
Is one typo really enough to get me rejected?
A single minor typo rarely sinks an application on its own, but it does register as a small negative signal, especially for roles involving writing or attention to detail. Multiple errors, or an error in something critical like the company name, carry much more weight.
What if a job posting includes a hidden instruction to test attention to detail?
Some companies intentionally bury a specific instruction in the job posting — like asking you to include a certain word in your cover letter — specifically to filter out candidates who don't read carefully. Always read the full posting closely, not just the bullet-point requirements.
Can exaggerating my experience in a cover letter actually get me caught?
Often, yes. Interviewers frequently ask follow-up questions about specific claims made in a cover letter, and an exaggerated or fabricated detail tends to fall apart under a few direct questions. It's rarely worth the risk.
