Good vs Bad Cover Letter Examples

The Hook

❌ Avoid:

To Whom It May Concern, I am applying for the .NET Developer job. I saw it online. I have worked with .NET for a while and think I would be good at it.

✅ Do This:

Dear [Hiring Manager Name], I am writing to express my enthusiastic interest in the Senior .NET Developer position at [Company Name], as advertised on [Platform]. With X years of experience architecting robust, scalable solutions using .NET Core and Azure, I am confident my expertise in microservices and distributed systems aligns perfectly with your team's innovative projects and commitment to cutting-edge technology.

Why: The 'Good' example is specific, addresses the hiring manager directly, mentions the position and company, and immediately highlights relevant, quantified experience and skills that directly match common .NET developer requirements. It shows enthusiasm and research. The 'Bad' example is generic, informal, lacks specific details, and fails to convey any genuine interest or relevant qualifications, making it forgettable.

Frequently Asked Questions

How long should my cover letter be?

Ideally, a cover letter should be one page, comprising three to four concise paragraphs. Recruiters often scan these documents quickly, so brevity and impact are key.

Should I address it to "To Whom It May Concern"?

No, always try to find the specific hiring manager's name. A personalized salutation like "Dear Mr./Ms. [Last Name]" demonstrates attention to detail and genuine interest. If the name is truly unavailable, "Dear Hiring Manager" or "Dear [Team Name] Hiring Team" is acceptable.

Do I need a cover letter if the application doesn't explicitly ask for one?

While not always mandatory, submitting a tailored cover letter is highly recommended. It provides an additional opportunity to impress, explain gaps, or elaborate on unique qualifications that a resume alone cannot convey. It shows initiative.

How can I make my cover letter stand out?

Personalize it! Research the company's projects, values, and recent news, and weave this understanding into your letter. Share a brief, compelling anecdote about a relevant project or challenge you overcame, showcasing your problem-solving skills and passion for .NET development.

What if I don't have all the required skills listed in the job description?

Focus on the skills you *do* possess that are most relevant. If there's a skill you're actively learning or have foundational knowledge in, mention your eagerness and capacity to quickly acquire it. Avoid misrepresenting your abilities.

Should I repeat information from my resume in my cover letter?

No, the cover letter should complement your resume, not duplicate it. While you'll mention skills and experiences, elaborate on *how* you applied them, the *impact* you made, and *why* they are relevant to *this specific role* and company, rather than just listing them.

Is it okay to use a template for my cover letter?

You can use a template for its structure, but the content must be entirely customized for each application. Generic, unedited templates are easily spotted and can detract from your application.

What's the best way to end a cover letter?

Reiterate your enthusiasm for the role and the company, express confidence in your fit, and include a clear call to action, such as "I am eager to discuss how my skills can benefit your team in an interview." Use a professional closing like "Sincerely" or "Best regards," followed by your typed name.

Should I mention my salary expectations in the cover letter?

Unless explicitly requested in the job posting, it's generally best to avoid discussing salary expectations in your initial cover letter. This topic is typically reserved for later stages of the interview process.
