Cover letter best practices
Tailor Each Cover Letter to being a Big Data
Avoid generic letters. Customize your content to reflect the specific job description, company values, and how your experience aligns with their needs.
Use a Professional Format
Stick to a clean, business-like layout with consistent fonts, spacing, and margins. Match the formatting of your resume for a cohesive application package.
Address the Right Person
Whenever possible, address the letter to a specific individual (e.g., “Dear Ms. Johnson”). Use LinkedIn or the company website to find the hiring manager’s name.
Start with a Strong Opening
Capture attention in the first paragraph by stating the position, expressing genuine interest, and previewing the value you’ll bring to the role.
Highlight Relevant Achievements
Focus on 1–2 specific accomplishments that relate directly to the job. Use metrics, outcomes, or project details to demonstrate impact.
Show You Understand the Company
Demonstrate knowledge of the company’s mission, recent news, or culture. This shows you’ve done your homework and care about where you work.
Explain Career Transitions Briefly
If you’re changing industries, roles, or returning to work, provide context for your move and highlight transferable skills.
Keep It Concise and Focused
Limit your letter to one page and avoid repeating your resume. Aim for clarity and brevity—ideally 3–4 paragraphs.
Use a Confident, Professional Tone
Write assertively without arrogance. Avoid overused buzzwords unless supported by real examples.
Close with a Clear Call to Action
End with a confident statement of interest, and invite the employer to connect or schedule an interview.
Proofread Carefully
Typos and grammatical errors can ruin a strong letter. Review it multiple times, and consider reading it out loud or asking someone else to check it.
