Cover letters exist in a strange limbo. Many job seekers believe no one reads them. Many hiring managers say they do — at least for candidates who make it past initial screening. The practical reality: a cover letter rarely gets you an interview on its own, but a good one can tip the balance when you're in the "maybe" pile.
The mistake most people make is treating the cover letter as a prose version of their resume. That adds nothing. A cover letter should do what a resume cannot: explain context, demonstrate specific interest, and connect your experience to this particular role.
What to Include
Opening: Name the Role and Show You've Done Research
Skip "I am writing to express my interest in..." — everyone writes that. Instead, open with something specific to the company or role:
"Your team's recent launch of [product/feature] caught my attention because I've spent the last three years solving similar problems at [current company]. The Senior Product Manager role looks like a natural fit for someone who has shipped B2B analytics tools to enterprise customers."
This demonstrates three things immediately: you know what the company does, you have relevant experience, and you've thought about why this specific role interests you.
Middle: Connect Your Experience to Their Needs
Choose 2-3 key requirements from the job description and address them with specific examples from your career. Don't restate your resume bullets — provide context that doesn't fit in a resume format:
- Why you chose a particular approach
- What you learned from a specific challenge
- How your experience at one company prepared you for what this role requires
- A brief example of a problem you solved that's relevant to the position
Closing: Clear Call to Action
End with a clear, professional close: "I'd welcome the opportunity to discuss how my experience with [specific skill/domain] aligns with what you're building at [company]. I'm available for a conversation at your convenience."
What to Avoid
Don't repeat your resume. The hiring manager has your resume. If your cover letter says the same things in longer sentences, it's wasting their time.
Don't be generic. "I'm passionate about [industry] and would love to contribute to your team" could be written for any company. If your letter works for multiple applications without changes, it's too generic.
Don't apologize for gaps or weaknesses. If you're changing careers or lack a specific requirement, frame what you bring instead of drawing attention to what you don't have.
Don't exceed one page. Three to four paragraphs is ideal. Hiring managers don't read long cover letters.
Format and Delivery
- Match your resume's header (same name, contact info, fonts)
- Use a professional greeting ("Dear [Name]" if possible, "Dear Hiring Manager" if not)
- Keep paragraphs short (3-4 sentences each)
- Submit as a PDF alongside your resume, or paste into the application's text field if required
When Cover Letters Matter Most
Cover letters carry the most weight in these situations:
- The posting explicitly requests one (not submitting signals low effort)
- You're changing industries or roles (the letter explains the transition)
- You have a personal connection to the company (the letter explains the connection)
- The role involves significant writing or communication skills
