Good vs Bad Cover Letter Examples

The Hook

❌ Avoid:

I am writing to apply for the Full Stack Developer job. I saw your ad online. I have experience in front-end and back-end development and think I would be a good fit.

Why: The 'good' example immediately states the position, where it was seen, and, most importantly, provides a specific reason for interest in *this particular company* and *its mission*, demonstrating research and genuine enthusiasm.

I have strong skills in React, Node.js, and PostgreSQL. I also know how to do testing. I worked on a dashboard project at my last job.

✅ Do This:

In my previous role at WebSolutions Inc., I spearheaded the development of a real-time analytics dashboard, utilizing React for an intuitive user interface and Node.js with PostgreSQL for a robust, high-performance backend. This project resulted in a 25% improvement in client data processing efficiency and directly contributed to a 15% increase in client retention by providing actionable insights. I also implemented comprehensive unit and integration tests (Jest, Cypress) which reduced critical bugs by 30% post-deployment.

Why: The 'good' example uses the STAR method (Situation, Task, Action, Result) to describe an achievement, providing specific technologies used and, crucially, quantifiable results (25% efficiency, 15% retention, 30% bug reduction). It shows *impact*. The 'bad' example merely lists skills and vaguely mentions a project without any detail, context, or demonstration of achievement.

Closing Paragraph (Call to Action)

❌ Avoid:

I hope you will consider my application. I am available for an interview if you want to talk. Thanks.

✅ Do This:

My comprehensive experience across the full stack, combined with a passion for creating performant and user-centric solutions, aligns perfectly with the requirements of this role and InnovateTech's innovative culture. I am eager to discuss how my expertise in scalable architecture and collaborative development can contribute to your team's success. Thank you for your time and consideration, and I look forward to hearing from you soon.

Why: The 'good' example confidently reiterates value, expresses eagerness for an interview, and maintains a professional tone. It clearly articulates the desire to move forward in the hiring process. The 'bad' example is passive, lacks confidence, and comes across as unenthusiastic, failing to make a strong final impression.

Frequently Asked Questions

How long should a Full Stack Developer cover letter be?

Ideally, your cover letter should be no longer than one page, typically three to four concise paragraphs. Recruiters and hiring managers have limited time, so get straight to the point and highlight your most relevant qualifications and enthusiasm.

Should I address the cover letter to a specific person?

Absolutely, whenever possible! Addressing the letter to a specific hiring manager or team lead shows you've done your research and are genuinely interested. Use LinkedIn or the company website to find a name. If you can't find one, 'Dear Hiring Team' or 'Dear [Company Name] Hiring Manager' is a professional alternative.

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

Don't be discouraged! Focus on the skills you *do* have that are highly relevant and transferable. Emphasize your ability to learn quickly, your problem-solving skills, and any experience you have with similar technologies. Highlight projects where you picked up new tools. Your full-stack adaptability is a huge asset here.

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

Avoid simply regurgitating your resume. While you'll touch on similar experiences, the cover letter is your chance to add context, tell stories, and explain the *why* and *how* behind your achievements. Elaborate on one or two key projects that best showcase your full stack capabilities and align with the job's requirements, using the STAR method.

Is it okay to use a cover letter template?

Using a template for structure and formatting is fine, but the content must be highly customized for each application. Copy-pasting generic phrases will be obvious and can hurt your chances. Personalize every paragraph to reflect your genuine interest in *that specific company* and *that specific role*.

How can I make my Full Stack Developer cover letter stand out?

To stand out: 1. Research the company thoroughly and mention specific projects, values, or technologies that excite you. 2. Quantify your achievements with numbers. 3. Showcase your personality and genuine passion for development. 4. Connect your unique full stack perspective to how you can solve their problems. 5. Proofread meticulously for perfection.

When should I not send a cover letter?

Only refrain from sending a cover letter if the application explicitly states 'no cover letter required' or if the application system doesn't provide an option to upload one. Even then, if there's an 'additional comments' or 'notes' section, you can often provide a brief, tailored message there.

What's the best way to send my cover letter?

Always follow the application instructions. If it's an online portal, upload it as a PDF (named professionally, e.g., 'FirstNameLastName_CoverLetter_FullStackDeveloper.pdf'). If you're emailing, attach it as a PDF and include a concise, compelling message in the email body that acts as a mini-cover letter, directing them to the attached document.

Should I include salary expectations in my cover letter?

Generally, it's best to avoid mentioning salary expectations in your cover letter unless the job application explicitly requests it. This topic is usually reserved for later stages of the interview process. If prompted, you can provide a salary range rather than a fixed number.
