How to Tailor Your Resume to Any Job Posting

Generic resumes get ignored. Research shows that 75% of resumes are rejected by Applicant Tracking Systems (ATS) before a human ever sees them — not because the candidate is unqualified, but because the resume doesn't contain the right keywords.

Here is exactly how to fix that.

What Is ATS and Why Does It Matter?

An Applicant Tracking System (ATS) is software that companies use to filter job applications before a recruiter reviews them. It scans resumes for keywords that match the job description and ranks or rejects candidates based on that match.

Common ATS platforms include Taleo, Greenhouse, Workday, and Lever. Most mid-size and large companies use one.

The problem: most resumes are written generically. They describe what you did at previous jobs using your own language — not the language the employer uses in their job postings. The ATS doesn't know those mean the same thing.

Step 1: Read the Job Posting Like a Document, Not a Description

Read the posting carefully and highlight or note:

- Exact skill names: "React" vs "ReactJS" vs "React.js" can all be treated differently by ATS. Use the exact version in the posting. - Repeated words: If "cross-functional" appears 3 times, it is important. - Required vs preferred: "Required: 3+ years Python" is weighted much higher than "Nice to have: experience with Kubernetes." - Job title language: If the posting says "Software Engineer" and your resume says "Developer," add the exact title somewhere.

Step 2: Make a Keyword List

After reading, create two lists:

1. Skills and tools you actually have that appear in the posting 2. Skills you have but described differently in your resume

For list 2 — this is your rewriting target. You are not adding skills you don't have. You are translating your experience into the employer's language.

Example: - You wrote: "Built web apps using JavaScript frameworks" - The job says: "Proficient in React and TypeScript" - Fix: "Built production web apps using React and TypeScript"

Step 3: Rewrite Bullet Points With the Right Keywords in the Right Places

ATS systems weight keywords more heavily depending on where they appear. The order of importance is roughly:

1. Job title / headline 2. Skills section 3. Bullet points in experience

The STAR format works best for bullet points: - Situation: brief context - Task: what you were responsible for - Action: what you did (use the job's exact verbs) - Result: quantified outcome

"Managed social media" → "Grew Instagram engagement 47% in 6 months by creating a consistent content calendar and A/B testing post formats, resulting in 12,000 new followers."

Every bullet point should answer: what did I do, using which tools/skills, and what measurable result did it produce?

Step 4: Match the Summary or Objective Section

The first 3–5 lines of your resume are critical. Write 2–3 sentences that:

- Use the exact job title from the posting - Mention your years of relevant experience - Include the top 2–3 required skills

Example: "Senior Software Engineer with 6 years of experience building scalable web applications using React, TypeScript, and Node.js. Led teams of 4–8 engineers shipping customer-facing features at a Series B SaaS company."

Step 5: Check Your Skills Section Format

The skills section is the fastest ATS win. Make sure:

- Skills are listed as individual items, not sentences - You use the exact tool names from the job posting - You don't bury skills inside paragraphs of text

Bad: "I have experience with various cloud platforms and CI/CD tools." Good: `AWS | GCP | Docker | GitHub Actions | Terraform`

Step 6: Use Hirabble to Automate This Process

Doing this manually for every job application is time-consuming. Hirabble automates the entire process: upload your resume and paste the job description, and it produces a fit score, an AI-rewritten resume using the job's exact language, a tailored cover letter, and a keyword gap report — in under 60 seconds.

Common Mistakes to Avoid

Using a PDF without text layer: Scanned PDFs cannot be read by ATS. Always save as a text-searchable PDF or Word document.

Using tables and columns: Many ATS parse left-to-right and can mangle content inside tables. Use a simple single-column format.

Putting keywords only in images or headers: ATS usually can't read text inside images or decorative headers.

Making it too long: Keep to one page for under 10 years of experience. ATS systems don't penalize length but recruiters who receive the ATS-filtered shortlist do.

Keyword stuffing: Listing "Python Python Python" doesn't help and looks suspicious to human reviewers. Use each keyword naturally 1–3 times.

The Honest Truth About ATS

Even a perfectly optimized resume only gets past the ATS filter. After that, a human recruiter reads it in 6–10 seconds on average. The keywords get you through the door — but clear writing, strong results, and honest experience are what get you the interview.

Tailor for the machine. Write for the human.
