Cover Letter Mistakes That Can Hurt Your Application
Cover Letter Mistakes That Can Hurt Your Application
A cover letter should do something your résumé cannot: explain why your experience makes sense for a specific role. It gives the employer context, shows how you communicate, and helps connect your background to the position. No single mistake guarantees that an application will be ignored, but certain patterns can make a cover letter much easier to skip.
The Mistakes That Make a Cover Letter Easy to Ignore
One of the most common problems is repeating the résumé. A cover letter should not retell your education, jobs, and activities in the same order. Instead, choose one or two experiences that are especially relevant and explain why they matter for the role.
Another mistake is sending the same letter everywhere. If the only thing that changes is the company name, the message will probably feel generic. A stronger letter mentions something specific about the position, organization, mission, or work that genuinely connects with your interests or experience.
Students also sometimes focus too much on what they hope to gain. A sentence such as “This internship would give me valuable experience” may be true, but the employer also wants to know what you can contribute. Try to show how your skills or previous work could be useful in the position.
Vague claims are another problem. Saying you are “hardworking,” “motivated,” or “a strong communicator” does not prove much on its own. A brief example is usually more convincing.
Length matters too. A cover letter does not need to include your entire academic and professional history. One page is usually enough to highlight the strongest evidence and leave the reader interested in learning more.
Finally, do not treat proofreading as optional. A typo may be minor, but using the wrong company name or job title can make the letter feel careless. Always check names, details, grammar, and formatting before submitting.
Cover Letter Mistakes and Quick Fixes
A Quick Before-and-After Example
Weak
I am a hardworking student with excellent communication skills, and I believe this internship would provide valuable experience for my future career.
Stronger
As communications lead for our student association, I coordinated a semester-long campaign across three campus channels. That experience is one reason I was drawn to this internship’s focus on digital outreach.
The stronger version works because it gives evidence instead of relying on adjectives. It also connects the student’s experience directly to the role, which makes the letter feel more intentional.
The Final 30-Second Check
Before submitting, ask yourself:
● Could this letter be sent unchanged to another company?
● Did I add information instead of repeating my résumé?
● Did I give evidence for the qualities I claim to have?
● Are the company name, role, greeting, and grammar correct?
A strong cover letter does not need to tell your entire story. Its job is to give the reader a clear reason to look more closely at the rest of your application. Specific examples, genuine interest, and careful proofreading usually matter far more than trying to sound impressive.
Before You Submit, Give Your Cover Letter a Final Review
A polished cover letter can help you make a stronger first impression. ProofReading checks your existing writing for grammar, clarity, consistency, and errors before you submit.
