5 Cover Letter Mistakes That Cost You the Interview

The Hard Truth About Cover Letters

Most cover letters are a waste of everyone's time. They're generic, self-focused, and add nothing to the application. But a well-crafted cover letter can be the difference between getting an interview and getting ignored — especially for competitive roles or career transitions.

The goal of a cover letter isn't to repeat your resume. It's to tell the story behind your resume: why you want this specific role at this specific company, and what unique value you bring.

Mistake #1: Starting With "I"

"I am writing to express my interest in the Marketing Manager position..." Every recruiter has read this sentence thousands of times. It's the fastest way to signal that your letter is generic.

The fix: Open with something that immediately demonstrates your knowledge of the company or your passion for the role. Example: "When [Company] launched its sustainability initiative last year, I knew this was the kind of organisation I wanted to build my career with."

Mistake #2: Summarising Your Resume

"As you can see from my attached resume, I have 7 years of experience in software development..." The recruiter can see your resume. Don't waste their time repeating it.

The fix: Use the cover letter to add context that your resume can't. Explain a career transition. Tell the story behind your biggest achievement. Describe why you're passionate about the company's mission.

Mistake #3: Focusing on What You Want, Not What You Offer

"This role would be a great opportunity for me to grow my skills in..." The employer doesn't care what you want — they care what you can do for them.

The fix: Reframe every sentence around value delivered. Instead of "I want to develop my leadership skills," write "I'm ready to bring the leadership approach that grew my team from 3 to 15 people to your engineering organisation."

Mistake #4: Being Too Long

Hiring managers spend an average of 30 seconds on a cover letter. Three to four short paragraphs, maximum one page. Each paragraph should have one clear purpose: hook, value proposition, company fit, call to action.

Mistake #5: Generic Closing

"I look forward to hearing from you" says nothing. Close with confidence and a specific next step: "I'd welcome the opportunity to discuss how my experience scaling B2B SaaS products can contribute to [Company]'s growth targets. I'll follow up next week, but please feel free to reach me at [phone] or [email]."

The Cover Letter Formula That Works

Paragraph 1 — The Hook: Open with something specific about the company or role that demonstrates genuine interest. Mention the role title.

Paragraph 2 — Your Value Proposition: What's the one most relevant achievement from your career? Tell that story with numbers. Connect it directly to what the employer needs.

Paragraph 3 — Company Fit: Why this company specifically? Reference something real: their product, mission, recent news, culture, or values.

Paragraph 4 — Call to Action: Express enthusiasm, invite a conversation, and provide your contact information.
