HackerNews JD Matcher (Who Wants to be Hired)

Every month, a new thread is created on HackerNews called Who Wants to be Hired where people who are looking for a new role can post their details. It's mostly tech talents. It's a good source of amazing candidates if you're hiring tech or tech adjacent roles like we are at JigsawStack!

On average there are 600+ profiles posted every month, and it's a pain to go through them one by one.

So we wrote a script that uses JigsawStack's AI scraper and Prompt Engine to automatically scrape the profiles, structure the data, fix it then score it using AI by comparing it to our JD. We email the top candidates for an interview :)

We've found amazing candidates who will be joining us at JigsawStack and it's saved us a lot of time!

Note: This is not a perfect solution, it worked for our hiring process but might not for yours, use at your own risk!

Stack

• Bun
• JigsawStack
• Resend

Here's how you can use it:

• Clone the repo
• Install dependencies with bun install
• Create a .env file and add your JigsawStack API key. Use the .env.example as a reference.
• All config is in config folder in the root. You can replace the JD.md with your own JD in markdown format.
• Run the script with bun run index.ts

You can view the example of how results look like here

Config

{
  "promptKey": "post_description",
  "hnWhoWantsToBeHiredURL": "https://news.ycombinator.com/item?id=42575535", //replace this to the latest month URL
  "jd_file_name": "config/JD.md",
  "min_rating": 8, //lower or increase the rating of the candidates
  "email": {
    //optional, only if you want to automatically email the candidates
    "email_file_name": "config/email.md",
    "from": "YourName <[email protected]>",
    "subject": "Saw your post on HN for a new role",
    "replyTo": "[email protected]"
  }
}

You can replace hnWhoWantsToBeHiredURL with the latest month URL. Find all who wants to be hired threads here.

Replace the JD.md with your own JD in markdown format.

Data

After running the script, you can find the data in the data folder.

• hn_profile_scrape.json - the raw data scraped from the HackerNews thread
• hn_profile_clean.json - the cleaned data with the structured profiles
• hn_profile_fixed_with_scores.json - the data with the scores and formatting fixes
• results.json - the file results with the scores and the email

Since the data is cache, scraping the initial data is only done once. To re-scrape the latest data, you can run bun run clean_data to remove all files in the data folder. Then run the script again.

Email

After running the script, you can email the candidates using Resend by running bun run email.ts.

You can edit the email.md file to change the email content and the email object in config/config.json to change the email settings.

Future

This is an example of how we used JigsawStack to help with hiring. This script can be transformed to work for other forums like job portals, like reddit. You could even reverse it to find job opportunities in Who is hiring?
