Build a Job Application System with Claude

Spend one evening letting Claude interview you into a master file and CV. After that, each application is a tailored pack built in minutes.

Most people tailor each application from scratch, so each one takes an hour and the CV drifts a little further from the truth every time. Turn it around. Give Claude one evening to interview you and write down everything you've done, then build one master CV you're happy with. Every job after that is the same move: paste the post, get a pack built only from your own record.

Before you start: this uses the Code tab in the Claude desktop app (download it at claude.ai/download), which needs a paid plan from $20 a month. Step 1 sets up the folder where Claude saves every file in this tutorial.

That folder is the difference from pasting into ChatGPT. Your record lives in files on your computer, so application number seven reads the same master file as number one, and you never paste your CV or explain your career again. Pick your role below to see the examples in your field.

  1. step 01 / 07

    Set up your folder

    Make an empty folder called job-search anywhere on your computer. Open the Code tab in the Claude desktop app, select Local, click Select folder and choose job-search. Then ask Claude to make the three folders below and watch them appear in the Files pane. Every later step saves into them, so your record stays in one place.

    Prompt
    Set up this folder for my job search. Make a career-vault folder for my record, with a versions folder inside it for old CVs and samples, and an applications folder for one folder per job. Then tell me what each one is for.

  2. step 02 / 07

    Let Claude interview you

    Don't start with your CV. Start by letting Claude ask the questions, one at a time, from your education onward. Answer out loud with a dictation tool if you have one: people say far more than they type, and the detail you say out loud is what the later steps are built from. Keep answering until Claude runs out of questions. That's dozens of turns, not one, so budget an evening.

    Prompt
    I'm looking for a new job. Interview me about my whole career so you can build a complete record of me. Ask one question at a time, starting from my education. Push for numbers, decisions and things that went wrong. Don't write anything yet.

  3. step 03 / 07

    Save the master file of you

    The master file is not a CV. It's everything you said, organized, and it's long on purpose. Ask Claude where it saved the file, open it, and correct anything wrong now. Every application you make later inherits whatever is in this file, mistakes included. Leave out your national ID number, date of birth, home address and anything else you wouldn't print on a CV: the file stays on your computer, but Claude reads it every time you apply.

    Prompt
    That's enough for tonight. Write everything I've told you into career-vault/master-file.md: education, every role with dates, projects, numbers, tools, what went wrong and what I learned. Keep my own words where you can. Where have you stored this?

  4. step 04 / 07

    Give Claude the CV format you like

    Find a CV layout you like and hand it to Claude as a template. Keep it plain: one column, a standard font, bullets and bold only, no tables, icons or sidebars. Applicant tracking systems read text, not design, and fancy layouts are where they scramble. Keep it short too. One page is the usual norm in North America, two in Europe and Australia. Applying in Bangladesh? Local employers often expect a photo, two referees and a longer CV, while international and remote roles want the plain format above with no photo and no personal details such as father's name, religion or marital status. If you apply to both, ask Claude for two templates.

    Prompt
    Here's a CV I like the look of: career-vault/versions/format-sample.pdf. Turn it into a template at career-vault/resume-template.md. One column, bullets and bold only, no tables, no icons. Two pages at most.

  5. step 05 / 07

    Build your master CV, then make it true

    Now Claude fills the template from the master file. This master CV is your boilerplate: not tailored to any job yet, but a version you'd be comfortable sending anywhere. Push back on every line until it's something you could defend for five minutes in an interview.

    Prompt
    Build my master CV in career-vault/resume.md using the template and only what's in master-file.md. Every bullet starts with a verb and ends with a result. Then show me the lines you're least sure about.

    what you should see

  6. step 06 / 07

    Paste a job post and ask for the pack

    From here on, every job gets the same treatment. Copy the full post, paste it in, and ask for an application pack. Claude tailors the master CV against the post and writes everything else from your career vault, so you're editing, not starting from zero.

    Prompt
    I want to apply to this position. Make me an application pack in career-vault/applications/: a tailored resume, a cover letter, answers to the form questions, and interview prep. Use only what's in my career vault, and tell me where I don't fit.

    Click a violet field and type your own details, then copy.

    what you should see

  7. step 07 / 07

    Read the gaps before you send

    Read every file before it goes out. Claude can't make you a stronger candidate than your master file says you are, and you don't want it to: the invented line is always the one the interviewer asks about. When the fit is weak, ask for the pack anyway and decide with the gaps in front of you. The cover letter still opens on your strongest match: a missing must-have gets one honest line in the middle, and a missing nice-to-have gets nothing. Check the interview prep the same way, because rehearsed answers are where made-up detail creeps back in.

    Prompt
    The fit is weaker than I hoped. Make me the pack anyway, but don't stretch anything to cover the gaps. Open the cover letter on my strongest match, handle any missing must-have in one line in the middle, and show me the opening.
