Work out what the job needs, shortlist the people worth meeting and book their interviews, all with free tools and prompts you can copy and paste.

Most teams hire from an inbox and a spreadsheet. A hundred CVs land in your email, you read the first 40 properly, and the rest blur together. Then come days of back-and-forth to book interviews.

Here's how to hire for free, without reading every CV yourself or chasing interviews over email.

The short version

What you need: three free tools.

  • Claude (an AI chat): you paste in the prompts, and it does the writing and the comparing.
  • Tally (forms): holds your apply form, where candidates apply.
  • Cal.com (booking): candidates pick their own interview time.

What you do: copy the seven prompts below into one Claude chat, in order. They take you from working out what the job needs, to a job post and apply form, to comparing applicants and sending interview invites. Claude does the work at each step. You check it and make every decision.

What you'll have in 30 minutes:

  • A benchmark to check every applicant against.
  • An apply page where candidates answer the questions that matter to you.
  • A way for candidates to book their interviews based on your availability.

This guide follows hiring best practices from professional HR bodies (SHRM and CIPD). The free tools save you time, and you're still set up to hire the best applicant for you.

Step 1: Work out the responsibilities and requirements

Open claude.ai and sign up free. In Settings, then Privacy, switch off model training, so applicants' details stay private.

Run every prompt in this guide in the same chat, in order. After each step, Claude tells you which prompt to copy next.

Tip: answer Claude's questions out loud with the microphone button in the Claude app. Long, messy spoken answers give it more to work with than a few typed lines.

Claude asks you a few questions, writes the responsibilities, and waits for your OK before it writes the requirements.

Step 1 prompt: Work out the responsibilities and requirements

Before you move on, check:

  • Would the person doing this job recognise every responsibility as real work?
  • Could you tell from a CV whether someone meets each requirement?

If not, ask Claude to make it more specific.

Step 2: Build a skills profile

A skills profile is how you tell the people worth meeting from the ones whose CVs make claims they can't back up. With AI, every CV looks good now, which makes it hard to tell applicants apart. This is your benchmark.

It lists the skills this job needs and what each one looks like at three levels. The prompt below builds one for your role, fitted to your company.

Step 2 prompt: Build a skills profile

One skill from a skills profile, short-form video making, with what beginner, intermediate and expert look like and the level needed
One skill from a skills profile, short-form video making, with what beginner, intermediate and expert look like and the level needed

One skill from our test run, for a made-up Content Creator job.

Before you move on, check:

  • Is each level the lowest that would still do the job well?
  • If most say expert, ask Claude which ones really need it.

Step 3: Write the questions for your apply form

A CV shows what someone has done, not whether they can start on your date or work your hours. A few yes/no questions check that.

Step 3 prompt: Write the questions for your apply form

Four yes/no questions on an apply form: the work schedule, living in Dubai, the visa and the start date
Four yes/no questions on an apply form: the work schedule, living in Dubai, the visa and the start date

The questions from our test run, as applicants see them.

Before you move on, check:

  • Is "yes" the answer you want for each question?
  • Would some people really answer no? If everyone would say yes, cut the question.

Step 4: Write the job post

Claude asks about your website, perks, salary and hours, then writes the post that sits at the top of your apply form.

Step 4 prompt: Write the job post

Before you move on, check:

  • Read it as the person you want to hire. Would they recognise the job?
  • Is every perk real?

Step 5: Build your apply form in Tally

First, set up Tally (you only do this once):

  • Sign up free at tally.so.
  • In Claude, go to Customize, then Connectors, then Browse connectors. Search for Tally, click Connect and allow access. This lets Claude build your form and read the applications.
Claude's Customize page, Connectors tab, with the Tally connector showing as connected
Claude's Customize page, Connectors tab, with the Tally connector showing as connected

Once connected, Tally shows under Customize, then Connectors.

Then Claude builds the form in your Tally account.

Step 5 prompt: Build your apply form in Tally

The top of the form from our test run. The job and company are made up.

Before you share it, check:

  • Fill in the form once yourself, including the CV upload.
  • Then delete your test answer in Tally.

Step 6: Compare applicants

When the applications come in, they all land in one table in Tally: each applicant's details, answers and CV in one row, instead of spread across your inbox.

The Submissions table in Tally, with five made-up applicants, each with their CV file and portfolio link in one row

Applications from our test run (made-up applicants). Scroll right in Tally to see each person's answers.

To compare them, click "Download file uploads" in Tally to get all the CVs (Claude can't open them inside Tally). Drag them into the chat with the prompt below, up to 20 at a time.

Tip: More than 20 applicants? Claude takes up to 20 files per chat, and a free account can run out partway through a big pile. So work in batches of 20: for each new batch, start a new chat, paste in your skills profile from step 2, then the step 6 prompt, and attach the next 20 CVs. Then put the top people from each batch side by side. A paid Claude plan gives you more room.

Step 6 prompt: Compare applicants

A ranked table of five made-up applicants, with the level each one showed for each skill and two practical flags

The ranked table from our test run (made-up applicants). Want it as a spreadsheet? Ask Claude: "Create a spreadsheet from your last answer."

Before you move on, check:

  • Open the top two or three applications yourself.
  • Does the proof Claude quoted match what they wrote?

Step 7: Send interview invites

First, set up Cal.com (you only do this once):

  • Sign up free at cal.com and connect your calendar.
  • Add a video tool (Google Meet, Zoom or Cal.com's own video), so every booking gets a link.
  • Create a booking type, for example "Interview: 30 min", with your free times, a 15-minute gap and at least a day's notice. Pick your video tool as the location.
  • Book a test slot, check the confirmation has a video link, then cancel it and copy your booking link.

Then add your booking link where the prompt says.

Step 7 prompt: Send interview invites

A Cal.com booking page for a 30-minute interview on Zoom, with open times to pick from
A Cal.com booking page for a 30-minute interview on Zoom, with open times to pick from

What applicants see when they open your booking link.

Then: send the invites. Candidates pick a time, the interview lands in both calendars, and Cal.com sends them reminders. To tell everyone else, your form's thank-you message already covers it, or ask Claude for one short email you can send in BCC.

Questions people ask

Is it really free to hire this way?

Yes. Claude, Tally and Cal.com all have free plans, and this guide uses only what's in them. Tally's free plan includes file uploads up to 10 MB, so applicants can attach a CV. In our test run, a free Claude account compared five applicants and their CVs without hitting a limit.

How long does it take to hire with free tools?

About 30 minutes of your own time per hire, plus the days you wait for applications. Signing up for each tool takes a few minutes the first time.

Can I use ChatGPT or another AI instead of Claude?

Steps 1 to 4 and 7 work in any AI chat. Steps 5 and 6 use Claude's Tally connector to build the form and read the applications. With another AI, you'd build the form in Tally yourself and download the applications.

Is it safe to share applicants' CVs with Claude?

Switch off model training first (see step 1). The step 6 prompt tells Claude to ignore names, age, gender, nationality, photos and where people studied or worked. Share only the CVs you need, and delete the chat when the hire is done.

Will Claude reject good applicants?

No. The prompts tell Claude not to reject anyone. It flags "no" answers, shows its proof and leaves the shortlist to you.
