Writing a resume
Cover letter: add proof the resume cannot hold
Write a cover letter only when the posting or the portal asks for one, or when one proof will not fit on the resume. Three short paragraphs: why this job, one story with a number, a clean close. Greenhouse and Workday often store the letter as a paste field — keep it plain text. Do not repeat the resume.

Key takeaways
- · If the posting says optional, skip the letter unless you have one fact the resume cannot carry — a relocation date, a license, a named project.
- · One page, three paragraphs, no wallpaper of adjectives. Recruiters skim on a phone between Workday tabs.
- · Name a tool or a result once. Repeating every resume bullet is how the letter gets closed.
- · Paste fields in Greenhouse and Workday strip design. Type the letter as text, then attach a matching .docx if they also want a file.
- · Pair the letter with a parse-safe resume: check the resume even when the letter itself is not parsed like a CV.
When a cover letter earns a slot — and when it wastes an evening
Key takeaway: Optional means optional. Write when you have one proof the resume cannot hold, or when the form requires a file.
A cover letter is not a second resume. It is a short argument that you understood this posting. Workday, Greenhouse, Taleo, Lever, and iCIMS may all offer a “cover letter” upload or a text box. Some hiring managers never open it. Some municipal and nonprofit panels still score it. Match the process, not a blog that says every job needs three pages of passion.
Write when the posting requires it. Write when the box is required in the application. Write when one fact will not fit a bullet: you move in six weeks, you already hold the city electrician license, you ran the grant they named. Skip it when the posting says optional and your resume already maps the nouns. A empty letter of “I am excited to apply” is worse than no letter.
Internal moves are a special case. The hiring manager may know you. The ATS record may not. A short letter that names the requisition and the project you already shipped can connect the Workday profile to this req. Do not recap your whole badge history.
Honest skips
- Mass apply with the same paragraph. Greenhouse recruiters notice identical first lines.
- Letters that only restate the resume in full sentences.
- Letters addressed to “Dear Hiring Manager” when the posting names a person — use the name.
- Designed PDFs with a sidebar matching a two-column resume. Paste fields will mangle them.
For the resume that sits next to the letter, use how to write a resume and tailor a resume to a job. The letter cannot rescue a file that Taleo stored without dates.
What Greenhouse and Workday actually store from a cover letter
Key takeaway: Many portals keep the letter as plain text. Fancy layout is for a human email, not for the paste box.
Workday often has a cover letter attachment and a comments box. The attachment may never be parsed into skill fields the way a resume is. Recruiters still open it in a viewer. If the PDF is an image, they see a blank. Selectable text still matters.
Greenhouse frequently uses a text area. Bold, columns, and letterhead vanish. Write in paragraphs a phone can finish. iCIMS and Taleo vary by employer: some require a file, some ignore it. When both upload and paste exist, paste a clean version and upload the same words as .docx — not two different stories.
Keyword stuffing in a letter looks worse than on a resume because a human is more likely to read the first eight lines. Name the posting’s tool once in a sentence you can defend. Do not list every noun from the ad. Lever search may still hit the resume; the letter is for the person who clicked through.
Length: under one page. About 250–400 words is enough. If you need 800 words, you are writing a memo. Municipal electrician packets sometimes want a longer narrative — follow that packet, then still use headings a human can scan.
File name: FirstLast_CoverLetter_Role.pdf, matching the resume name. Joke filenames show up in the same recruiter queue as the resume. Pair with a parse-safe resume via the ATS checker.
Rewrite letter lines that only repeat the resume: three transforms
Key takeaway: The letter should add a story, a constraint, or a named match. If the line could sit on the resume, cut it.
These rewrites are from grant writing, a city electrician application, and a school library — not generic “passion for the role” samples. Steal the pattern.
Before
I am writing to express my interest in the Development Officer position at your esteemed organization where I can grow.
After
I am applying for the Development Officer role. Last year I wrote the narrative for a $180k IMLS-adjacent grant that funded two part-time cataloguers; I can walk you through the logic model we used with the board.
Before
As a licensed electrician I am responsible for all electrical work and I work well with teams in a fast-paced environment.
After
I hold a City of Dayton journeyman license (exp. 2027). On the last school-bond job I pulled 14 panels on nights so the library stayed open, with zero repeat callbacks on the punch list.
Before
I have always loved books and believe I would be a great fit for your library media specialist opening.
After
I am applying for the Library Media Specialist posting at Eastview K–8. I taught weekly database lessons in Destiny and cut overdue notices 30% by moving homeroom checkout to a two-scanner setup.
Do not invent a grant or a license. If you lack a number, use scope: number of classrooms, miles of feeder, languages of the collection. “Night shift in an occupied school” is a number. “Excellent communicator” is not.
A 10-step cover letter playbook you can finish in 40 minutes
Key takeaway: Gather the posting and one story first. Writing the greeting before you have proof is how people ship wallpaper.
Have the job ad, your resume, and one episode you can tell in four sentences. If the resume is still a two-column Canva, fix that in the builder before you draft the letter. The portal will show both.
- Confirm the posting asks for a letter or that you have one non-resume fact. If neither, skip.
- Find a name. Posting, LinkedIn of the hiring manager, or “Hiring committee for [Role].” Avoid “To whom it may concern.”
- Paragraph 1: the exact job title, where you saw it, and one line of fit (license, years in this setting, a tool they named).
- Paragraph 2: one story with a number or a named system. Not three stories.
- Paragraph 3: availability, work authorization only if relevant, thank you, and that you attached the resume.
- Cut every sentence that restates a resume bullet without adding context.
- Read it aloud. If you wince at “passionate,” delete the sentence.
- Paste into a plain text editor. Restore paragraph breaks. That is what Greenhouse will keep.
- If they also want a file, export selectable .docx or PDF. No letterhead image covering the name.
- Upload. Open the preview. Confirm the paste box did not eat the first paragraph. Then submit the resume that still parses.
Step 4 is the one people overload. Three anecdotes in one paragraph is a memoir. Pick the story closest to the posting’s first required skill.
If Workday truncates at a character limit, cut paragraph 3 first, then adjectives, never the license line. Details on resume keywords that should stay on the resume: resume keywords.
Cover letter choices: do this, skip that
Key takeaway: Optimize for one proof a tired reader can finish. Wallpaper and design theater fail in paste boxes.
Use this while you edit. If a choice is not in the table, ask: would this sentence still matter if they never opened the resume? If yes, keep it. If no, it belongs on the resume or nowhere.
Human-readable vs. portal-hostile cover letter choices
| Topic | Do | Don’t |
|---|---|---|
| When | Required field, or one fact the resume cannot hold. | Optional box filled with “I am excited to apply.” |
| Length | One page, ~250–400 words, three paragraphs. | Two pages of biography or a slogan under a logo. |
| Proof | One numbered story, one named tool. | Every resume bullet rewritten as a sentence. |
| Greeting | Named person or “Hiring committee for [Role].” | To whom it may concern, or the wrong company from a mail merge. |
| File | Plain text paste + selectable .docx if they want a file. | Canva letter with a sidebar; image-only PDF. |
| ATS | Assume paste strips design; keep the resume parse-safe. | Keyword footer in the letter; white text tricks. |
Creative roles sometimes want a designed PDF. Send it if they asked. Still paste a text version if Greenhouse has a box. Two channels, one story. Do not let the designed file be the only copy of your name.
Length, tone, and country habits that change the letter
Key takeaway: US letters stay short and specific. Some EU processes still want a more formal Anschreiben. Follow the packet, then still tell one true story.
United States private sector: skip unless asked, then keep it tight. No photo. No salary history in the letter unless they demanded it — and even then, many US employers cannot ask. UK letters can be a bit longer; still one page. German Anschreiben is often expected with the Lebenslauf; it can be more formal, still needs a fact, not only courtesy formulas.
Do not copy US casual tone into a German packet, or German formality into a US startup Greenhouse. Match the posting’s language. If the ad is dry and legal, your letter can be dry and legal. If the ad is plain, write plain.
Salary, visa, and notice period: one sentence in paragraph 3 if it changes whether they can hire you. Do not hide a visa need in a P.S. Do not open with salary. Recruiters in Lever will get to logistics; they need the proof first.
What to do today: pick one posting that requires a letter, run the 10 steps, paste into a text box, then score the resume. The Enhance CV home page returns you to the builder. The letter lives in a notes app until the resume parses.
Edge cases: no name, career change, and “upload any additional documents”
Key takeaway: The structure stays. You only change which proof you lead with, and whether you write at all.
No name on the posting: “Hiring committee for Electrician, Facilities Division” is better than a fake first name you guessed from LinkedIn and got wrong. Wrong names are remembered.
Career change: the letter is one of the few places a pivot belongs. One paragraph on the transferable system (grant logic, panel schedules, Destiny) and one on what you are not pretending to have done. Do not write a novel. See career change resume for the file beside it.
“Additional documents” with no mention of a letter: upload a license PDF or a writing sample they asked for, not an unsolicited essay. Extra files clutter iCIMS and rarely get opened.
After a silent Workday status: the letter is rarely why you vanished. Check whether the resume parse dropped contact. Fix that first.
FAQ
Do I need a cover letter in 2026?
Only if the posting or the application form requires one, or if you have a single fact the resume cannot hold. Many Greenhouse and Workday reqs make the letter optional and hiring managers skip it. An empty excitement paragraph can hurt more than silence. When you do write, keep it to one page and one story.
How long should a cover letter be?
Under one page, usually 250–400 words, three paragraphs. If a municipal or academic packet asks for a longer narrative, follow that packet. Paste boxes in Workday may truncate; put the license and the story first. Recruiters rarely finish a two-page letter on a phone.
Should a cover letter repeat my resume?
No. Repeat the job title and one matching noun, then add a story, a date, or a constraint the bullets cannot carry. If every sentence is a resume bullet with “I” in front, delete the letter. Humans notice the copy-paste. Parsers do not reward it either.
Do ATS systems read cover letters?
Sometimes the file is stored and searched; often it is a blob a recruiter opens later. Greenhouse paste fields keep text, not design. Workday may attach a PDF that never fills skill fields. Assume a human may read the first screen. Keep the resume parse-safe either way.
How do I address a cover letter with no name?
Use “Hiring committee for [exact job title]” or the team name in the posting. Guessing a first name from a wrong LinkedIn profile is remembered for the wrong reason. If the posting names a person, use that name and spell it correctly.
Can I use the same cover letter for every job?
You can keep a skeleton: greeting pattern, one reusable story, a close. You cannot keep the first paragraph. Swap the job title, the company, and the noun from this posting. Identical letters across 40 Greenhouse apps get recognized. One tailored letter beats ten generic ones.
Should I send a cover letter as PDF or in the text box?
Follow the form. If there is a paste box, paste plain paragraphs. If they want a file, selectable .docx or PDF. When both exist, make the words match. Do not put the only copy of your name in a letterhead image that Taleo cannot read.
Does a cover letter help me pass an ATS?
Rarely as a keyword trick. The resume is what Workday maps into fields. A letter can help the human who opens your Greenhouse card. Stuffing tools into the letter will not repair a missing email on the resume. Check the resume with the Enhance CV ATS checker before you polish adjectives in the letter.
Keep the resume in a layout parsers already map
Open the Enhance CV builder, keep your facts, and write the letter beside a file that still contains your contact data. Then score the resume against the posting.
