7 Cover Letter Mistakes That Cost You the Interview

Most cover letters do more harm than good. They repeat the CV, waffle about passion, and fail to answer the one question every hiring manager is actually asking: why should I meet this person?

Here are the seven mistakes we see most often — and how to fix them.

Mistake 1: Starting with "I am writing to apply for…"

Every recruiter reads this sentence fifty times a day. It tells them nothing about you and wastes your most valuable real estate — the opening line.

Fix: Open with your single strongest credential or most relevant achievement. Make them keep reading.

"In eight years managing infrastructure projects for the NHS, I've delivered £12m of capital works without a single overrun — which is why the Head of Estates role at Great Ormond Street caught my attention immediately."

That's a cover letter that gets read.

Mistake 2: Summarising your CV

A cover letter is not a prose version of your CV. If you're listing the same jobs, dates, and responsibilities, you're wasting the reader's time.

Fix: Use the cover letter to tell the story behind the CV. What's the thread connecting your experience? Why does it make you uniquely suited to this role?

Mistake 3: Making it about you, not them

"I am looking for a role that will develop my skills" — this is about what the job does for you, not what you do for them.

Fix: Frame every point in terms of value to the employer. What problem does your hiring solve for them?

Mistake 4: Generic letters sent to multiple employers

Recruiters can smell a template. If your cover letter doesn't reference the company by name, mention something specific about the role, or show any evidence you've read the job description — it goes in the bin.

Fix: Spend five minutes researching the company. Reference one specific thing: a recent project, a stated value, a growth area. It takes minutes and makes a significant difference.

Mistake 5: Burying the lede

In journalism, "burying the lede" means putting the most important information deep in the story. Most cover letters do this — your best point appears in paragraph three.

Fix: Lead with your headline. Put your strongest, most relevant point in the first two sentences.

Mistake 6: Ending weakly

"I look forward to hearing from you" — passive, forgettable, zero momentum.

Fix: End with a confident, specific call to action.

"I'd welcome the opportunity to discuss how my experience in multi-site FM delivery maps to your current programme. I'm available for a call this week — please feel free to reach out directly."

Mistake 7: Sending without a final check

A typo in a cover letter signals carelessness — the exact opposite of what you're trying to demonstrate. One error can undo a strong application.

Fix: Read it aloud. Read it backwards. Get someone else to read it. Then submit.

The one question your cover letter must answer

Before you send any cover letter, ask yourself: have I clearly answered "why this role, at this company, right now?"

If the answer isn't obvious in the first paragraph, rewrite until it is.
