TL;DR
- Cover letters that restate the resume in paragraph form get skimmed in seconds; the ones that get actually read make a specific, evidenced case for this particular role.
- Specificity in a cover letter has to come from somewhere — usually a real story you've already documented, not one written fresh under deadline pressure the night before applying.
- A cover letter built from a documented example reads as considered; one written generically to match keywords in the job post reads as exactly that.
- The strongest cover letters connect one real thing you did to one real thing the role needs — not a summary of your whole career, just the sharpest relevant point.
- Keeping a running record of specific work stories means you're choosing the best-fitting one for each cover letter, not inventing something plausible on the spot.
Why most cover letters get skimmed
Most cover letters restate the resume in sentence form — “I have five years of experience in X and am excited about Y” — which tells the reader nothing they didn't already know and took nothing from the actual job posting.
What makes one get read
A cover letter that references something specific to the role, backed by a specific thing you actually did, signals that you understood the job and have real evidence you'd be good at it. That combination — specific ask, specific evidence — is rare enough to stand out.
Where the specific evidence comes from
It has to come from somewhere real: a documented story, not something invented for the occasion. If you've been keeping a running record of real work, the cover letter becomes a matter of picking the single best-fitting example, not writing one from scratch.
One example beats a full career summary
A cover letter doesn't need to cover your whole career. One well-chosen, well-evidenced example connected clearly to what the role needs does more work than a paragraph trying to summarize everything.
Frequently asked questions
How long should a cover letter be?
Short — a few tight paragraphs. Length isn't what gets it read; a specific, relevant example is.
Do I need a different cover letter for every application?
The framing should change to match the role, even if the underlying example stays the same — pulling from a documented set of real stories makes this fast rather than a rewrite each time.
What if I don't have a story that obviously fits the role?
Look for the closest match in scope or skill rather than an exact one, and be explicit about the connection — “this is different from X role, but the same judgment call applies.”
Is it okay to skip the cover letter if it's optional?
If it's genuinely optional and you don't have a strong, specific example to include, a short one focused on a single relevant point still outperforms a generic one — or no letter, in most cases.
