Common cover letter mistakes: 9 that sink your letter and how to avoid them

TL;DR

Most cover letters aren't rejected because the applicant is weak but for repeated, minutes-to-fix mistakes: a generic template sent to everyone, paragraphs retelling the CV verbatim, a worn opener the recruiter has read a hundred times, essay enthusiasm with zero proof, a warm register aimed at a formal body or stiff formality aimed at a startup, "improved" numbers that collapse in the interview, and a spelling error in a document claiming writing skill. The rule that covers them all: any sentence that adds no information about you for this specific job gets deleted.

1. The verbatim template - visible from line one

A recruiter receiving fifty letters a week reads the same trending template several times a day: identical phrases in identical order, sometimes with unreplaced brackets left in - "applying for [position]". The generic letter doesn't hurt because it's badly written - its prose is usually fine - but because it says the one thing you never want said: this applicant didn't give our job ten undivided minutes. Use examples as a skeleton and replace every fact with your own, as our field-by-field examples guide shows.

2. Retelling the CV paragraph by paragraph

The CV and the letter are two documents with two different jobs: the CV is the complete record, the letter is a focused argument. When the letter summarizes the whole CV - "I worked at X, then moved to Y, then earned Z" - the recruiter reads the information twice and the argument zero times. The fix: pick your two strongest proofs directly relevant to this job and build on them; everything else already has a home in the CV.

3. Worn-out openers - the banned list

A detail from our own kitchen: when we built Taqdeem's AI letter writer, we programmatically banned specific openers because they're so worn the letter starts dead. The same list works as your ban list: in English, "I am writing to apply...", "I am excited to...", "Please accept this letter..." - sentences that say nothing except that a letter is being written, which is already visible. In Arabic, the literal calques like «أنا متحمس جدًا لهذه الفرصة» that read as English in Arabic characters. The alternative: start at the intersection - name the role and your strongest qualification for it in the very first sentence.

"Your Financial Analyst posting (F-104) asks for credit-analysis depth; I bring six years of exactly that"

Don't

"I am writing to express my sincere interest in the opportunity to possibly join your esteemed organization"

4. Essay enthusiasm with no proof

"Ambitious, hardworking, passionate, works under pressure, fast learner" - five adjectives in nearly every letter, none verifiable, so their information value is zero. The simple test: could any other applicant write the same sentence about themselves without lying? If yes, delete it. Replace every adjective with a fact: for "hardworking," an achievement number; for "fast learner," a certificate finished in record time or a system mastered in weeks.

5. The wrong register for the wrong employer

The mistake runs both ways: excess warmth toward a government body or major bank reads as flippancy, while stiff formality with long honorifics toward a tech startup reads as rigidity and cultural distance. Read the job posting itself as the signal: formal posting language calls for a formal letter; direct, lively posting language tolerates a lighter professional register. Saudi government bodies specifically have their complete rules in our government and Jadarat letter guide.

6. "Improved" numbers and re-based facts

The most dangerous mistake on the list, because it's the only one that follows you past the reading: an inflated number, or - subtler - a true number converted into a claim it can't support. From building our own letter writer: we banned the model from re-basing any figure, the way a CV's "budgets of five million SAR" becomes "I manage monthly multi-million budgets" because the posting asked for monthly-budget experience - every individual number in the new sentence is true, and the composite claim has no evidence. That kind of conversion survives the letter reading and collapses at the first interview question, and it costs all your credibility, not just the sentence.

The one number rule

Every number in your letter must exist in your CV in the same form, and must survive the interview question "how did you calculate that?"

7. The identical four-paragraph mould in every letter

The four-part structure is an excellent starting point - our own examples build on it - but it becomes a defect when it turns into an iron mould: four equal paragraphs with identical connectives ("which aligns with your requirements" in every one) regardless of the job. Another lesson from building the AI writer: we banned those repeated connective phrases by name because they'd become a tic visible from a distance. Let your strongest material decide the shape: sometimes one dense proof paragraph beats two thin ones.

8. Talking about your need, not theirs

"This position is an excellent opportunity to develop my skills and build my career" - a perfectly honest sentence in a perfectly wrong place: the employer isn't hiring you to develop your skills but to solve their problem. Reverse the direction of every such sentence: what changes for them with you there? The paragraph that answers that with proof is the one the reader remembers.

9. Sending unproofread - and the price doubles here

A spelling error in a CV is a slip; in a cover letter it's a verdict: the letter's very existence claims you write well and mind details, and one error falsifies both claims at once. Proofread twice with a time gap, read it aloud (the ear catches what the eye skips), and check the employer name and job title specifically - the two places where copy-paste residue from a previous application most often survives.

Taqdeem's letter writer was built on these exact rules: banned from worn openers, re-based numbers, and invented facts, writing from your own CV in a register you choose - with one free letter per account to try it.

Frequently asked questions

What's the fastest way to check my letter before sending?

Three questions: could any sentence fit another applicant unchanged? (Delete or personalize it.) Does every number exist in my CV? (Fix or cut.) Did I read it aloud without stumbling? Then one final spelling pass over the employer name and job title.

Is using AI to write the letter a mistake in itself?

The mistake isn't the tool but the use: a generic machine letter with none of your facts commits mistakes one and four simultaneously. The right use is a tool that writes from your real data, then you review and personalize - which is why we built ours to cite only what your CV actually contains. See also our guide on detecting AI-written text.

I sent the letter with the wrong company name - do I resend?

If it went out minutes ago, send a corrected copy with one short line owning the error without a lengthy explanation - a quick, graceful correction sometimes counts in your favor. If real time has passed, the damage is likely done, and your time is better spent on the next application with a tighter review.
