Honestly, the cover letter is the part of the job hunt everyone hates the most. You’ve already spent hours tweaking your resume, making sure every bullet point starts with a strong action verb, and then you see that little upload button for a "Letter of Interest." It feels redundant. You might think, "Can’t they just see my experience on the resume?" But here’s the thing: learning how to write a cover letter for a job is actually your only chance to speak directly to a human before you even get in the room. It’s your narrative.
Most people get this completely wrong. They download a template from 2005, swap out the company name, and call it a day. Boring. Hiring managers at places like Google or small startups see those templates a thousand times a week. If you want to stand out, you have to stop writing like a textbook and start writing like a person who actually wants the job.
Why Most People Fail at the Cover Letter
The biggest mistake? Treating the cover letter as a prose version of your resume. If I’m the hiring manager, I’ve already seen your resume. I know where you went to school. I know you worked at Salesforce for three years. I don’t need you to tell me again in paragraph form.
A great cover letter answers the "Why?" why are you applying here? Why do you care about this specific problem? According to career expert and "Ask a Manager" creator Alison Green, a cover letter should provide information that a resume can't. It’s about your personality, your work style, and your specific interest in the company’s mission. If your letter could be sent to five different companies by just changing the name at the top, it’s a bad letter. Period.
How To Write A Cover Letter For A Job That Actually Gets Read
First, forget the "To Whom It May Concern" opening. It’s stiff. It’s dated. It’s kinda lazy. If you can find the name of the hiring manager on LinkedIn or the company website, use it. If not, "Dear [Department] Hiring Manager" works way better. It shows you at least know which department you’re trying to join.
The hook matters more than you think. Don't start with "I am writing to apply for the position of Marketing Manager." They know that. They're reading the letter you attached to the Marketing Manager application. Instead, start with a "hook" that shows you understand the company’s current challenges or successes. Maybe they just launched a new product, or maybe you've been a long-time user of their software. Lead with that connection.
The Meat of the Letter: The "Why You" and "Why Them"
This is where you connect the dots. You need to pick two or three specific achievements from your past that prove you can do the job they're hiring for. But don't just list them. Tell a tiny story.

Example: "When I was at TechFlow, we realized our churn rate was spiking. I didn't just run reports; I spent a week sitting in on customer support calls to hear the complaints firsthand. Based on that, I redesigned our onboarding flow, which cut churn by 12% in three months."
See the difference? That tells me how you think. It tells me you're proactive. It tells me you're not afraid to get your hands dirty.
The Customization Trap
You’ve probably heard you need to customize every letter. You do. But that doesn’t mean starting from scratch every single time. You can have a "skeleton" for your cover letter. Keep your best "story" paragraphs—the ones that show your universal skills—but rewrite the intro and the outro for every single application.
Research the company culture. If you’re applying to a law firm, keep it professional and traditional. If you’re applying to a creative agency or a gaming company like Valve, you can afford to be a bit more casual, even humorous. Look at their social media. How do they talk to their customers? Match that energy.
Technical Details and Formatting
Keep it short. Nobody wants to read a three-page manifesto. Half a page to one full page is the "sweet spot." Use a clean font like Arial, Calibri, or Georgia. Save it as a PDF unless they specifically ask for a Word doc.
- Header: Your contact info, the date, and their contact info.
- The Greeting: Use a specific name if possible.
- The Hook: Why this company and why now?
- The Evidence: 2-3 specific "mini-stories" of your success.
- The Call to Action: Mention you’re looking forward to discussing how you can help them.
- The Sign-off: "Best regards" or "Sincerely" are safe bets.
Addressing the "Gap" or Career Change
If you have a gap in your resume or you’re switching industries, the cover letter is your best friend. This is where you explain the "pivot." If you spent ten years in retail and now you want to work in HR, focus on the "transferable skills." You’ve dealt with conflict resolution, scheduling, and people management every day. Own it. Don't apologize for the gap; explain what you did during that time—traveling, caregiving, or upskilling—and move on.
Common Myths to Ignore
Some "career coaches" will tell you to use crazy colors or graphics to stand out. Don't. Unless you're a graphic designer, it usually just makes the letter harder to read. Other people say you should "restate the job description" to beat the Applicant Tracking Systems (ATS). While keywords matter, the cover letter is primarily for the human who looks at the file after the ATS clears you. Write for the human.
Actionable Next Steps
- Find a "Target" Job: Pick one job you actually want, not just ten you're "fine" with.
- Research the "Pain Points": Look at the company’s recent news or the job description’s "Requirements" section. What is the #1 problem they need this person to solve?
- Draft Your Hook: Write one sentence about why you admire the company or how you relate to their mission.
- Pick Your Two Stories: Find two moments in your career where you solved a similar problem to the one they have now.
- Read It Out Loud: If you stumble over a sentence or it sounds like a robot wrote it, delete it. If it doesn't sound like something you'd actually say in an interview, fix the tone.
- The PDF Check: Save the file as "YourName_CoverLetter_Company.pdf" to make it easy for the recruiter to find.
Getting a job is a numbers game, but a high-quality, personalized cover letter significantly tilts the odds in your favor. It turns you from a list of dates and titles into a real person with a brain and a voice. Stop overthinking the "rules" and start focusing on the connection. That’s how you get the interview.
