How to Write a Cover Letter: A 4-Part Structure That Passes the Screening

The 4-Part Cover Letter Structure That Passes Screening

Most cover letter prompts ultimately ask four things: motivation to apply, job competency, experience (achievements), and aspirations after joining. Remember these four axes and you can frame any prompt.

1. Motivation to apply - Answer "why this company, this role." Throw out sentences that fit any company, like "because I want to grow." Connect the company's products and business direction with your experience in a single sentence.
2. Job competency - Take the qualifications from the job posting verbatim and match them to the abilities you have. If the posting says "data analysis," that keyword must appear in your sentences too, with evidence.
3. Experience and achievements (STAR) - The real examples that back up your competency. Covered in detail below.
4. Aspirations after joining - Write not vague resolutions but a concrete plan, like "within 6 months / 1 year of joining, I will do X."

Three Principles: Conclusion-First, Concrete Numbers, Job Connection

Once you've framed the structure, there are three principles to observe at the sentence level.

First, write conclusion-first. Put the conclusion at the very front. Start with "I have experience improving an inventory management process to cut processing time," and then attach the situation and process. The reader should grasp the gist even if they read only the first sentence. Placing the key point in the first line of each answer, like a subheading, is also a method.

Second, turn abstract words into numbers. Change "I handled many customers" into "I handled an average of about 40 inquiries a day," and "I contributed to sales" into "Over three months, I proposed and ran a campaign that improved the repurchase rate." Without numbers, a sentence loses its power to prove. That said, inventing numbers that don't exist is fatal at the verification stage, so pull them from real experience.

Third, connect every sentence to the job. Whether it's a club, a part-time job, or a department project, end with "so how does this experience apply to the role I'm applying for." The key is translating the competency gained from the experience into the language of the job, rather than the experience itself.

Frame Experience With STAR - Giving Your Story a Backbone

The experience question, which carries the most weight, won't wobble if you organize it with the STAR technique.

• S (Situation) - When, and against what background, in one or two concise sentences. If the background explanation runs long, your own role gets buried.
• T (Task) - What goal or problem you were assigned in that situation.
• A (Action) - What you specifically did. This is the heart of the cover letter and the part you write at greatest length. Describe it as "I did," not "the team did."
• R (Result) - What changed because of that action. Include numbers if you have them; if not, be specific about what you learned or improved.

Let's get a feel for it with an example. "In a department team project, gathering the presentation materials kept piling up right before the deadline and caused delays (S/T). I organized each part's due date and owner into a table in a shared document and proposed a mid-point check two days before (A). As a result, we finished all three subsequent presentations a day early, and my teammates kept using this method the next semester too (R)." It's short, but situation, action, and result stand out clearly.

Approaches by Prompt

Even though the wording of prompts differs by company, the intent lies within the earlier four parts. First find the core keyword of the prompt.

• "Motivation to apply and plans after joining" - Researching the company is where it's won. Grasp the business direction from the website, job posting, and recent news, and tie one of them to your experience.
• "Job-related competency and experience" - Break the posting's qualifications down item by item and place one matching example against each.
• "Growth background and values" - It looks like a personality question, but you must ultimately land it on your work attitude. If you mentioned diligence, connect it to how that shows up in your work.
• "Failure or conflict experience" - Devote the volume to the response and lessons afterward, rather than the failure itself.

Always observe the character limit, but it's best to fill at least 80% of the minimum. Too short looks careless, and going over gets cut off.

Common Mistakes That Cost You Points

Even with good content, a single one of the mistakes below can collapse the impression you make.

• Listing abstract words - Repeating only "passion, diligence, communication skills" with no evidence. Prove it with examples and numbers instead of adjectives.
• Copying and getting the company name wrong - Pasting online samples or a successful applicant's cover letter as is gets caught by similarity checks, and submitting without deleting another company's name is grounds for instant rejection. Always re-check the company and job title before submitting.
• Motivation centered on you, not the company - Having only "for my own growth" and nothing about "what I'll contribute to the company."
• Burying the conclusion and rambling - Writing where the conclusion comes at the very end, or where a long background explanation buries the key point.
• Spelling and typos - Read as a lack of fundamentals. Before submitting, read it aloud and run it through a spell-checker once more.

AI Only Up to the Draft

Using generative AI to frame the skeleton of your cover letter or polish sentences is a useful tool. However, submitting text the AI wrote as is is not recommended. Because AI doesn't know your actual experiences and numbers, its sentences are blunt and generic. When many applicants use similar prompts, the expressions overlap and lose distinctiveness, and some companies even check whether AI was used. Use AI only up to the draft stage-framing the structure and suggesting expressions-and be sure to fill in the concrete experiences, numbers, and job connections in your own words. After getting a draft, just ask yourself of each sentence, "Is this an example that's uniquely mine?"

FAQ

I don't have any special experience worth putting in a cover letter.

You don't need grand experience. A small moment where you "spotted a problem and changed something" is enough-whether in a part-time job, a department assignment, a club, or volunteer work. What matters is not the scale but whether it's structured with STAR and connected to the job.

How much of the character limit should I fill?

Going over the limit gets cut off and becomes a point deduction, so always stay within it, but I recommend filling at least 80-90% of the lower bound. Too short looks like a lack of effort. Density matters more than length, so cut unnecessary background explanation and allocate volume to action and results.

Can I reuse the same cover letter for several companies?

You can reuse basic material like experience examples, but the motivation and job-connection parts must be rewritten for each company. Managers quickly spot text copied without any research on their company. At minimum, adjusting the opening and closing to fit the company name, business direction, and prompt keywords is the way to raise your pass rate.
