A great cover letter can be the difference between landing an interview and getting lost in the pile. Here's how to write a concise, impactful cover letter that gets results.

The One-Page Rule

Recruiters spend an average of 7 seconds scanning your cover letter. Keep it to one page with:

  • 3-4 paragraphs maximum
  • 250-400 words total
  • Plenty of white space
  • Standard business letter format

The Perfect Cover Letter Formula

Opening Paragraph (2-3 sentences)

Hook the reader immediately:

  • State the position and how you learned about it
  • One compelling reason why you're perfect for the role
  • Show enthusiasm without being generic

EXAMPLE

As a data scientist with 5 years of experience building ML models that increased revenue by 30%, I was thrilled to see your opening for a Senior Data Scientist at TechCorp.

Middle Paragraph(s) (4-6 sentences)

Connect your experience to their needs:

  • Pick 2-3 requirements from the job description
  • Provide specific examples of relevant achievements
  • Use keywords from the job posting
  • Quantify your impact with numbers

EXAMPLE

At my current role at DataCo, I led the development of a recommendation engine that increased user engagement by 45% and generated $3M in additional revenue. Your requirement for experience with real-time data pipelines aligns perfectly with my recent project building a streaming analytics platform processing 10M events daily.

Closing Paragraph (2-3 sentences)

Call to action:

  • Reiterate your interest
  • Mention next steps
  • Thank them for their consideration

EXAMPLE

I'm excited about the opportunity to bring my expertise in machine learning and data engineering to TechCorp's innovative team. I look forward to discussing how I can contribute to your continued growth. Thank you for your consideration.
