80% of cover letters are generic and forgettable. Don't be part of that 80%.
This guide helps you write compelling cover letters that get you interviews.
- Why Cover Letters Matter
- The Cover Letter Structure
- Writing Each Section
- Common Mistakes to Avoid
- Examples by Experience Level
- Templates You Can Adapt
The Reality:
- 50% of hiring managers won't consider a candidate without a cover letter
- For junior roles, cover letters show communication skills and genuine interest
- A great cover letter can overcome lack of experience
What a Good Cover Letter Does:
- Shows you understand the company and role
- Demonstrates you can communicate clearly
- Highlights why you're specifically interested (not just mass applying)
- Gives context to your CV (career change, bootcamp grad, etc.)
- Shows personality and cultural fit
Paragraph 1: The Hook (Why you're writing + initial enthusiasm)
Paragraph 2: Why You're a Great Fit (2-3 relevant achievements)
Paragraph 3: Why This Company (genuine interest, research)
Paragraph 4: The Close (enthusiasm + call to action)
Total length: 250-400 words (one page max)
Purpose: Grab attention immediately, show genuine interest
Formula:
I'm excited to apply for [ROLE] at [COMPANY]. [One sentence about why this excites you or what caught your attention].
Examples:
✅ Good:
"I'm excited to apply for the Junior Software Developer role at Stripe. As someone who's used your API in three personal projects, I've long admired how you've made payment infrastructure accessible to developers worldwide."
"I'm writing to express my strong interest in the DevOps Engineer position at GitLab. Your all-remote culture and commitment to transparency align perfectly with my values, and I'm excited about the opportunity to contribute to infrastructure that powers millions of developers."
❌ Bad:
"I am writing to apply for the position posted on your careers page."
"My name is John Doe and I would like to be considered for the Software Developer position."
Pro Tips:
- Be specific about the role (not "a position at your company")
- Show you know something about them (product, mission, culture)
- Be genuine - forced enthusiasm is obvious
Purpose: Prove you can do the job with specific examples
Formula:
[Your background statement]. [Achievement 1 with metric]. [Achievement 2 with metric]. [Optional: What this experience taught you that's relevant].
Examples:
✅ Good (Junior Developer):
"I recently completed an intensive software engineering bootcamp and have been building production applications for the past six months. At my current startup, I built a customer dashboard using React and Node.js that serves 10,000+ users with 99.9% uptime. I also increased our test coverage from 40% to 85%, catching multiple critical bugs before production. This experience taught me the importance of code quality and thorough testing - skills that would serve your team well."
✅ Good (Career Changer):
"After five years in project management, I transitioned to software engineering because I wanted to build solutions, not just coordinate them. In my first development role, I automated a deployment pipeline that reduced release time from 4 hours to 15 minutes, and I learned Kubernetes to migrate our infrastructure to a container-based architecture. My background in managing cross-functional teams has made me particularly effective at collaborating with product, design, and QA."
✅ Good (Student/Recent Grad):
"As a Computer Science student graduating this May, I've focused my studies on distributed systems and cloud computing. I built a high-availability web service as my capstone project that handles 100,000+ requests daily, and I contributed to an open-source Kubernetes project where my PR improved resource scheduling efficiency by 15%. Through my internship at [Company], I learned how to write production-quality code and work effectively in an agile team."
❌ Bad:
"I have experience with Python, JavaScript, and React. I am a hard worker and a team player. I am passionate about technology and eager to learn."
Pro Tips:
- Use specific numbers and outcomes
- Connect your experience to their needs
- Mention technologies/skills from the job description
- Show, don't tell (don't say "I'm a fast learner", prove it with an example)
Purpose: Show you've done research and have genuine interest
Formula:
[What specifically attracts you] + [How your values/interests align] + [Optional: What you admire or want to contribute to]
Examples:
✅ Good:
"I'm particularly drawn to [Company] because of your commitment to developer experience. Having read your engineering blog posts about improving build times and developer tooling, I share your philosophy that investing in developer productivity pays dividends. I'd love to contribute to your infrastructure team and help make deployments even faster and more reliable."
"Your company's mission to make financial services accessible resonates deeply with me. As someone from a low-income background, I've experienced firsthand how lack of access to good financial tools can be limiting. Working on [Product] would be an opportunity to build something that genuinely improves people's lives."
"I've been following [Company]'s engineering team on Twitter and have been impressed by your thoughtful approach to scaling challenges. Your recent blog post about migrating to microservices mentioned similar challenges I faced at my current company. I'm excited about the opportunity to work on distributed systems at scale."
❌ Bad:
"I want to work at your company because you offer great benefits and have a good reputation."
"Your company is a leader in the industry and I would learn a lot."
Pro Tips:
- Reference specific things: blog posts, products, culture docs, tech talks
- Avoid generic statements that could apply to any company
- Connect their mission/values to your own experience or beliefs
- Mention specific teams, projects, or challenges that excite you
Purpose: Show enthusiasm and invite next steps
Formula:
[Reiterate enthusiasm] + [Specific thing you'd like to discuss] + [Polite call to action]
Examples:
✅ Good:
"I'm excited about the possibility of joining [Company] and contributing to your mission of [specific goal]. I'd love to discuss how my experience with CI/CD automation and infrastructure-as-code could support your team's goals. Thank you for considering my application - I look forward to the opportunity to speak with you."
"I'm confident my background in full-stack development and passion for developer tools align well with this role. I'd welcome the chance to discuss how I can contribute to improving [specific product/project]. Thank you for your time and consideration."
❌ Bad:
"Thank you for your time. Please contact me at your earliest convenience."
"I hope to hear from you soon. Thanks."
Pro Tips:
- Express genuine enthusiasm (but don't be desperate)
- Mention something specific you'd like to discuss
- Keep it brief and professional
- Thank them for their time
❌ "I am writing to express my interest in the position at your esteemed organization..."
This could be sent to any company. Make it specific.
Your cover letter should complement your CV, not repeat it:
- CV: Lists your experience
- Cover Letter: Provides context and narrative
❌ "This position would be a great opportunity for me to learn..."
Instead, focus on what you can contribute: ✅ "I'm excited to contribute my skills in [X] to help your team achieve [Y]..."
❌ Too humble: "I know I don't have much experience, but..." ❌ Too arrogant: "I'm the perfect candidate for this role..."
✅ Balanced: "While I'm early in my career, I've already made meaningful contributions such as [specific example]..."
This is an instant rejection. Proofread carefully.
- Use Grammarly or similar tools
- Read it out loud
- Have someone else review it
Keep it to one page (250-400 words). Recruiters spend 30 seconds scanning it.
❌ "I was responsible for the development of..." ✅ "I developed..."
Don't claim experience you don't have. Be honest but frame your experience positively.
Dear Hiring Manager,
I'm excited to apply for the Junior Software Developer position at Shopify. As a recent graduate of [Bootcamp] who's built e-commerce features in multiple projects, I'm particularly drawn to the opportunity to work on commerce infrastructure at scale.
During my bootcamp and subsequent freelance work, I've focused on building production-quality web applications. I developed a full-stack e-commerce platform using React and Node.js that handles real payment processing and has served over 500 users. I also contributed to an open-source inventory management system, where my feature to optimize database queries reduced load times by 60%. These experiences taught me not just how to code, but how to build reliable, scalable systems that real users depend on.
I'm drawn to Shopify because of your commitment to empowering entrepreneurs. My parents ran a small business, and I saw firsthand how the right tools can make a difference. Your focus on merchant success and your excellent developer documentation show that you truly understand your users. I'd love to contribute to making commerce better for everyone.
I'm confident my enthusiasm for learning, attention to code quality, and experience building e-commerce features would make me a valuable addition to your team. I'd welcome the opportunity to discuss how I can contribute to Shopify's mission. Thank you for considering my application.
Best regards,

Dear [Hiring Manager Name],
I'm writing to express my strong interest in the DevOps Engineer position at HashiCorp. After reading your case study on how [Company X] used Terraform to manage multi-cloud infrastructure, I'm excited about the opportunity to help more organizations achieve similar automation and efficiency.
I transitioned to DevOps engineering last year after five years as a systems administrator. In my current role, I've automated infrastructure provisioning with Terraform, reducing setup time from 2 days to 10 minutes and eliminating configuration drift across 50+ servers. I also built a CI/CD pipeline using GitHub Actions and Docker that increased our deployment frequency from weekly to daily. My background in traditional IT operations gives me deep appreciation for the problems that infrastructure-as-code solves.
HashiCorp's open-source philosophy and focus on multi-cloud tooling align perfectly with my experience and interests. I've used Terraform extensively and have contributed documentation improvements to the community. Working at HashiCorp would allow me to contribute to tools that I rely on daily while learning from the team that created them.
I'd love to discuss how my hands-on experience with infrastructure automation and my passion for DevOps practices can contribute to HashiCorp's continued success. Thank you for your consideration.

Dear [Hiring Manager Name],
I'm excited to apply for the Associate Cloud Engineer position at AWS. As a Computer Science student who's spent the past year building projects on AWS and studying for my Solutions Architect certification, I'm thrilled at the prospect of working on the platform that powers so much of the internet.
Through my coursework and personal projects, I've gained hands-on experience designing cloud architectures. For my senior capstone, I built a serverless application using Lambda, API Gateway, and DynamoDB that handles 100,000+ daily requests while costing less than $20/month. I also created a disaster recovery solution using S3 cross-region replication and automated failover with Route53. These projects taught me to think about scalability, cost-optimization, and reliability from day one.
I'm particularly excited about AWS's culture of customer obsession and innovation. Your principle of "Learn and Be Curious" resonates with me - I'm constantly experimenting with new AWS services and reading whitepapers to understand architectural best practices. Working alongside AWS engineers would accelerate my growth tremendously while allowing me to help customers solve their challenges.
I'd welcome the opportunity to discuss how my cloud architecture experience and passion for AWS can contribute to your team. Thank you for considering my application.
