## Overview

Most cover letters are ignored because they restate the resume. A good one does
three things in
under 300 words: shows you understand what the company needs, connects one or
two proof points from
your history to that need, and sounds like a human being. This skill drafts
cover letters anchored
to a specific posting, with a voice that matches the company's culture.

## When to use

- A job posting explicitly requests a cover letter

- - Applying to startups, nonprofits, or creative roles where the letter carries
  weight

- Career pivots where the resume alone doesn't explain the "why"

- Cold outreach to hiring managers or founders

- Referral-based applications where you want to name the connection gracefully

## Core concepts

- - - **The 3-paragraph structure.** Paragraph 1: the hook — which role, why
  this company specifically
  (one concrete reason). Paragraph 2: the proof — 1-2 achievements mapped to the
posting's top
  requirements. Paragraph 3: the close — enthusiasm, logistics, call to action.
- - - **Mirror, don't parrot.** Use the posting's vocabulary for skills and
  problems, but in your own
  sentences. This signals fit without sounding like a keyword list.
- - - **One story beats three claims.** A single vivid example ("cut churn 18%
  at a Series B SaaS") is
  more persuasive than "I am results-driven, collaborative, and innovative."
- - - **Voice calibration.** A fintech bank and a game studio want different
  tones. Read the posting
  and the company's public writing, then match formality — slightly warmer than
the posting, never
  colder.
- - - **The referral line.** If referred, say so in the first two sentences:
  "Jane Park suggested I
  apply" — it's the highest-signal sentence a letter can contain.
- - - **Brevity is respect.** Hiring managers skim. 250 words that get read beat
  600 words that get
  closed.

## Practical workflow

1. 1. 1. **Gather inputs.** Job posting (required), the candidate's tailored
   resume or key
   achievements, any connection to the company (referral, customer, prior
interaction), and the
   hiring manager's name if known.
2. 2. 2. **Extract the top 3 needs.** From the posting, identify the 2-3
   problems this hire must solve.
   The letter's proof paragraph maps directly to these.
3. 3. 3. **Find the hook.** What's genuinely interesting about this company to
   this candidate? A
   product they use, a technical decision they admire, a market they know.
Generic flattery
   ("industry leader") is worse than no hook.
4. 4. 4. **Draft tight.** Three short paragraphs, active voice, first person.
   Name the role and
   requisition if applicable. Keep sentences under 20 words.
5. 5. 5. **Insert proof, not promises.** Each claim about ability gets evidence:
   a metric, a project, a
   decision. "I led X, resulting in Y" — never "I believe I would excel at X."
6. 6. 6. **Close cleanly.** One sentence of genuine enthusiasm, one line on
   availability/next steps,
   professional sign-off with contact details.
7. 7. 7. **Tone check.** Read it aloud. If it sounds like a template with names
   swapped in, rewrite the
   hook and proof until it sounds like a person who did homework.

## Common pitfalls

- - - **Summarizing the resume.** If the letter just narrates the work history,
  it adds zero
  information. It should add context the resume can't: motivation, fit,
trajectory.
- - - **Starting with "I am writing to apply for..."** Dead on arrival. Open
  with the specific reason
  this role at this company, or the referral.
- - - **Apologizing for gaps or pivots.** Frame transitions as deliberate
  ("after five years in
  support, I moved into success to own outcomes end-to-end") — never defensive.
- - - **Over-formatting.** No tables, no headers with graphics, no unusual
  fonts. A clean letter in
  the same font as the resume.
- - - **Sending the same letter everywhere.** Recruiters can smell a mail merge.
  One customized
  paragraph per company is the minimum viable effort.
- - - **Forgetting the attachment basics.** PDF named
  "FirstName-LastName-Cover-Letter.pdf", and if
  pasted into a form, strip formatting that breaks in plain text.
