Most people paste their resume into ChatGPT and hope for the best. Your resume is not the problem. Your prompt is. Here is the four-skill Claude loop that diagnoses, scores, rewrites, and interview-preps your resume in a single session.

Why your current approach is not working

The typical move: open ChatGPT, paste the resume, type "make this better." Claude or any AI gives you generic improvements, you copy them in, and you still do not hear back. The issue is that a single vague prompt treats a multi-stage problem as if it were one thing.

Getting a job interview requires surviving four completely separate filters: an ATS scanner, a keyword match against the job post, a human recruiter's eye, and a hiring manager's questions. Each filter has different criteria. One prompt cannot address all four at once.

Here is what each skill does and why the order matters:

Each skill hands off to the next, so your resume compounds in strength at every step:

The prompts: exactly what to type into Claude

Run these in sequence in a single Claude conversation. Paste your resume text after each prompt where indicated.

You are a senior ATS specialist. Scan the resume below exactly as a top-tier ATS system would.

1. List every section, formatting choice, or phrase that would cause the ATS to skip or misread this resume.
2. For each issue, explain why it is a problem and give me the exact fix.
3. Score the resume's ATS compatibility out of 100 and tell me what score I need to reach before moving on.

Now act as a senior recruiter who has reviewed 1,000 job posts identical to this role.

1. List the top 15 keywords and phrases that appear most in those job posts but are missing or weak in my resume.
2. For each keyword, tell me exactly where and how to add it naturally.
3. Flag any section where my experience looks thin compared to what recruiters in this field expect to see.

Now act as a professional resume writer trained in Google's XYZ formula.

Rewrite every bullet point in my resume using the format:
"Accomplished [X], measured by [Y], by doing [Z]."

Rules:
- Every bullet must include a specific number, percentage, or dollar figure.
- Remove all vague phrases like "responsible for," "helped with," or "worked on."
- If a bullet lacks a metric, ask me one question to get the number before rewriting it.

Rewrite the full resume and present it cleanly below.

Now act as a senior hiring manager at a top company interviewing me for this role.

Using my rewritten resume and the job description:
1. Ask me the 10 questions you would most likely ask in the first interview.
2. After I answer each one, score my answer out of 10 and tell me exactly how to improve it.
3. Flag any answer that would make you hesitate to move me to the next round.

Start with question 1 now.

What each skill is actually fixing

How to run the loop effectively 🎓

1. Use one conversation for the whole loop. Claude carries context across all four skills. Starting fresh for each skill means it loses the fixes and rewrites from the earlier steps.
2. Fix the ATS issues before moving to the Recruiter skill. The Diagnoser gives you a score and a target. Do not progress until you hit it, otherwise the recruiter keyword fixes land on a structurally broken document.
3. Gather your metrics before the Rewriter skill. The Rewriter will ask for numbers. Have your performance reviews, project outcomes, and team sizes ready so you are not guessing.
4. Actually answer the Hiring Manager's questions out loud. Typing a polished answer is not the same as saying it. Use the mock interview to rehearse your spoken delivery, not just your written one.
5. Run the loop again for each new role you apply for. The Recruiter skill is job-specific. A resume optimised for a product manager role at a startup needs a different keyword pass than the same role at a bank.

The honest bit ✅

• Claude cannot access the actual ATS system a company uses. The Diagnoser prompt simulates common ATS behaviour based on known patterns. It catches the most common issues, but every system has quirks.
• The "1,000 job posts" framing is a prompting technique, not a live database query. Claude draws on its training data. It surfaces real patterns, but it is not running a live scrape of current job boards.
• Metrics you invent will hurt you. The Rewriter asks for numbers because they work. If you do not have a real figure, the prompt asks you a question to find one. Do not fabricate numbers, interviewers verify them.
• A great resume still needs a great application. This loop gets your resume past filters and prepares you for the room. The relationship, the referral, and the cover letter are still separate work this loop does not replace.
• Claude's output is a starting point, not a final draft. Read every rewritten bullet and confirm it accurately reflects what you actually did. AI rewrites can be technically polished but factually off if your original bullet was vague.
