Good vs Bad Cover Letter Examples

The Hook (Introduction Paragraph)

❌ Avoid:

I am writing to apply for the Machine Learning Engineer job. I saw your ad online and think I would be a good fit. I have experience with machine learning and am looking for a new role where I can use my skills.

✅ Do This:

I am writing to express my enthusiastic interest in the Machine Learning Engineer position at [Company Name], as advertised on [Platform where you saw the ad]. Having closely followed [Company Name]'s innovative work in [specific area, e.g., personalized recommendations/medical imaging], particularly your recent advancements in [mention a specific project or product], I am confident that my proven experience in developing and deploying scalable ML solutions, coupled with my passion for [relevant ML sub-field], makes me an ideal candidate to contribute to your team's success.

Why: The 'Good' example immediately grabs attention by demonstrating specific company knowledge and aligning personal skills with their work. It's enthusiastic, tailored, and hints at relevant experience. The 'Bad' example is generic, lacks enthusiasm, provides no specific details, and fails to differentiate the candidate from hundreds of others.

Frequently Asked Questions

How long should my Machine Learning Engineer cover letter be?

Ideally, your cover letter should be concise and fit on a single page, typically 3-4 paragraphs. Recruiters have limited time, so get straight to the point while providing impactful examples.

Should I address my cover letter to a specific person?

Absolutely, whenever possible! Addressing it to the specific hiring manager or team lead shows initiative and attention to detail. Research the company website, LinkedIn, or the job description for a name. If you can't find one, "Dear Hiring Manager" or "Dear Machine Learning Engineering Team" is acceptable.

What if I don't have direct professional ML Engineer experience?

Focus on transferable skills and relevant projects. Highlight academic projects, personal side projects, open-source contributions, hackathons, or internships where you applied ML concepts. Emphasize your learning agility, problem-solving skills, and passion for the field. Clearly articulate the challenges you tackled, the ML techniques you used, and the outcomes you achieved.

How can I make my cover letter stand out from other ML Engineers?

Tailoring is key. Research the company's products, values, and recent news, then explicitly link your skills and enthusiasm to their specific needs. Mention a specific project or publication of theirs that excites you. Quantify your achievements whenever possible (e.g., "improved model accuracy by 15%," "reduced inference time by 20%"). Showcase your unique perspective or a specific passion within ML.

Should I include a portfolio or GitHub link in my cover letter?

Yes, definitely! For an ML Engineer, a strong portfolio or active GitHub profile with relevant projects is incredibly valuable. Include a clean, hyperlinked URL in your contact information section. This allows recruiters to see your code, project documentation, and practical application of your skills.

Is it okay to use bullet points in a cover letter?

While generally cover letters are prose, a brief section (1-2 bullet points) can be effective in the middle body paragraphs to quickly highlight 2-3 key achievements or skills that directly match the job description. Use them sparingly to break up text and draw attention, but don't overdo it.

How important is it to mention soft skills in an ML Engineer cover letter?

Very important! While technical skills are foundational, soft skills like communication, collaboration, problem-solving, and adaptability are crucial for success in any engineering team. Weave examples into your narrative where you demonstrated these skills, perhaps in a team project or when explaining complex technical concepts to non-technical stakeholders.

Should I reiterate everything from my resume in the cover letter?

No, the cover letter shouldn't be a mere repetition of your resume. Instead, it should complement your resume by providing context, storytelling, and personality. Select 2-3 of your most relevant and impactful experiences or projects from your resume and elaborate on them, explaining *why* they make you a great fit for *this specific role* and company.

How do I handle employment gaps or career transitions in my cover letter?

Address them briefly and positively. If you have an employment gap, focus on what you did during that time (e.g., skill development, personal projects, education). If transitioning careers, highlight transferable skills and your motivation for moving into ML engineering, showing how your past experiences provide a unique perspective or valuable foundation.
