Cover Letter

A one-page document accompanying a job application that explains your motivation and makes the case for why you specifically are a strong fit.

A cover letter is a written introduction accompanying a job application. While a resume summarizes your experience, a cover letter explains your motivation — why this role, why this company, and why you specifically. A strong cover letter connects your background to the job's requirements with specific examples, demonstrates genuine knowledge of the company, and conveys something about your communication style and judgment that a resume cannot. It's the one part of the application process where voice matters.

Whether cover letters are read depends entirely on the company, the recruiter, and the role. At large companies receiving thousands of applications, many recruiters don't open cover letters unless the resume already looks strong. At smaller organizations, mission-driven nonprofits, editorial roles, and any job that explicitly tests writing ability, cover letters are weighted heavily and sometimes more carefully read than the resume itself. When the application marks the cover letter as optional, including a strong one never hurts — and is worth 30 minutes if the role matters to you.

The single most common cover letter mistake is writing a generic document that could apply to any company. Interviewers can tell immediately. A letter that opens with 'I am writing to express my strong interest in the [Job Title] position at [Company Name]' — a construction nearly indistinguishable from AI-generated text — tells the reader nothing and suggests the candidate didn't think carefully about the specific opportunity. The differentiator is specificity: a sentence that demonstrates real knowledge of what the company does, what it's trying to accomplish, and why you are personally invested in that mission.

AI-generated cover letters are now prevalent enough that humans reviewing applications have adjusted their evaluation accordingly. A cover letter that reads as AI-produced — fluent, generic, technically structured but personality-free — may do more harm than none at all, because it signals either that the candidate didn't bother writing it themselves or that they can't tell the difference between a real connection and a generated one. The bar for a cover letter to add value has risen precisely because the bar for producing one has dropped. A genuine, specific, personal letter that could only have been written by someone who actually wants this particular job is rarer — and more valuable — than it's ever been.

What Makes a Cover Letter Actually Work

  • Open with something compelling — not 'I am writing to apply for.' Lead with a connection, a specific observation, or a concrete reason you care about this particular company.
  • Connect your specific experience to the role's specific requirements — not generic competency statements, but named examples.
  • Demonstrate real knowledge of the company: a product you use, a problem you know they're solving, a recent development you found interesting.
  • Keep it to one page, 3–4 short paragraphs — recruiters don't read long cover letters, they skim them.
  • End with a clear, confident statement of interest and enthusiasm for next steps.
  • Proofread meticulously, especially the company name and recipient's name — errors here are disqualifying.

When Cover Letters Matter Most

  • Any role where writing is a core job function: content, communications, journalism, policy, law.
  • Small organizations where hiring is done personally and each application receives real attention.
  • Roles where you have an unusual background or non-linear path that needs framing.
  • Applications where you have a weak spot in your resume — a gap, a career pivot, a missing credential — that benefits from direct address.
  • Any time you have a genuine personal connection to the company's mission that isn't visible from your resume alone.

Example

A marketing manager applies to a climate tech startup. Instead of a generic opener, her cover letter reads: 'I've been following Watershed's carbon accounting platform for two years — I referenced your emissions methodology in a talk I gave at my company's sustainability summit last spring.' That specificity signals genuine interest and gets her interview scheduled within 48 hours of submission.
