Good vs Bad Cover Letter Examples
The Hook
❌ Avoid:
To Whom It May Concern,
I am applying for the Node.js Developer job. I saw it online. I have experience with Node.js and think I would be good at this job.
✅ Do This:
Dear [Hiring Manager Name],
I am writing to express my enthusiastic interest in the Senior Node.js Developer position at [Company Name], as advertised on [Platform]. With X years of experience building scalable backend solutions and a passion for leveraging Node.js to solve complex problems, I am confident I can make significant contributions to your innovative team, particularly given your focus on real-time data processing.
Why: The 'good' example is specific, addresses the hiring manager (or a specific role), states the position clearly, and immediately highlights relevant experience and a connection to the company's likely needs. The 'bad' example is generic, lacks specific direction, and provides no compelling reason to read further.
Body Paragraph - Demonstrating Skills
❌ Avoid:
I know Node.js and Express.js. I have worked with databases like MongoDB. I also know how to test code.
✅ Do This:
In my previous role at [Previous Company], I led the development of a high-performance microservices architecture using Node.js and NestJS, which resulted in a 30% reduction in API response times and significantly improved system stability. I also implemented robust testing strategies with Jest and Supertest, achieving 90%+ code coverage for critical modules, ensuring reliable deployments.
Why: The 'good' example uses strong action verbs, provides specific technologies, quantifies achievements (30% reduction, 90%+ code coverage), and explains the positive impact of their work. The 'bad' example is merely a list of skills without context, demonstration of expertise, or results.
Call to Action

✅ Do This:
My resume provides further details on my technical background, and I am eager to discuss how my expertise in building scalable Node.js applications and my commitment to clean code can benefit [Company Name]'s mission. Thank you for your time and consideration; I look forward to the opportunity to connect.
Why: The 'good' example is professional, reiterates interest and value, expresses gratitude, and clearly states a desire for an interview. The 'bad' example is abrupt, informal, and lacks professional courtesy, potentially leaving a negative final impression.
Frequently Asked Questions
How long should my Node.js Developer cover letter be?
Ideally, your 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 send a cover letter if it's optional?
Yes, absolutely. Even if optional, a well-crafted cover letter sets you apart by demonstrating your genuine interest, communication skills, and understanding of the role and company. It's an opportunity to make a personal connection that a resume alone cannot.
How do I address the cover letter if I don't know the hiring manager's name?
Always try to find a specific name through LinkedIn or the company website. If unsuccessful, use 'Dear Hiring Manager,' 'Dear [Company Name] Hiring Team,' or 'Dear Node.js Development Team.' Avoid generic greetings like 'To Whom It May Concern.'
What if I don't have direct professional Node.js experience?
Focus on transferable skills from other programming languages or relevant personal projects. Highlight your learning agility, contributions to open source, or any academic projects where you utilized Node.js. Emphasize your passion for Node.js and your commitment to continuous learning.
Is it okay to use a cover letter template?
While using a template for structure is fine, the content must be heavily customized for each application. Generic templates that aren't tailored to the specific job description and company will likely be disregarded. Personalization is crucial.
Should I mention salary expectations in my cover letter?
Generally, it's best to avoid mentioning salary expectations in your initial cover letter unless explicitly requested in the job posting. This discussion is usually reserved for later stages of the interview process.
How important is proofreading for a cover letter?
Proofreading is critically important. Errors in grammar, spelling, or punctuation can reflect poorly on your attention to detail and professionalism, regardless of your technical skills. Read it aloud, use grammar checkers, and ideally, have someone else review it.
What's the best way to follow up after submitting my cover letter and resume?
A polite follow-up email about a week after submission is appropriate. Reiterate your interest in the role and the company, and briefly mention a key skill or experience that makes you a strong candidate. Keep it concise and professional.
Should I attach my cover letter as a separate file or include it in the email body?
Follow the application instructions carefully. If there are no specific instructions, it's generally best to attach it as a PDF file, named professionally (e.g., 'FirstName_LastName_CoverLetter.pdf'). You can also include a brief, tailored message in the email body that references the attached letter.
