Method:

How we verify

Evidence: Article or interviewA newsletter, journalist or interview account of what happened.

Context: A practice application; no real hiring result.

Outcome

A writer fed ChatGPT a job description and his existing application details to produce a tailored resume (two attempts; the first looked too plain), a one-page cover letter and a LinkedIn summary with recruiter keywords. He then asked Gemini to play the hiring manager: it scored him 8.5 out of 10 with 'a very high probability of landing an interview', but said the documents were too 'tech-first' rather than 'finance-first' for this employer.

Agent

ChatGPT, Gemini

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Let's tailor my resume, cover letter and LinkedIn summary to one job, then review them as the hiring manager would.

What I'll share as we go:
- The job description and employer
- My current resume and extra details
- Tone I want

Rules:
- Use only my real experience; never invent jobs, numbers or skills.
- Match the job's requirements point by point in the cover letter.
- Add relevant keywords to the LinkedIn summary.
- Then review the documents as the employer would: score, strengths, and what the employer cares about that's missing.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: Tailored resume, one-page cover letter, LinkedIn summary and a hiring-manager review.

You'll know it worked when: every requirement in the job ad is addressed, with gaps fixed or noted.

- Read each document aloud and change anything that doesn't sound like me before sending.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
