It extracts resume details, identifies the applied job from the message, fetches the correct job description, and provides a summarized evaluation via Slack and tracking sheet. Perfect for HR teams using Slack.\n\n## **Who’s it for**\nThis workflow is designed for:\n- **HR Teams**, **Recruiters**, and **Hiring Managers**  \n- Working in software or tech companies using **Slack**, **Google Sheets**, and **n8n**\n- Who want to **automate candidate evaluation** based on uploaded profiles and applied job positions\n\n## **How it works / What it does**\nThis workflow is triggered when a **Slack user mentions the HR bot** and attaches a **candidate profile PDF**.\nThe workflow performs the following steps:\n1. **Trigger from Slack Mention**  \n   - A user mentions the bot in Slack with a message like:  \n     `@HRBot Please evaluate this candidate for the AI Engineer role.`  \n     (with PDF attached)\n2. **Input Validation**  \n   - If no file is attached, the bot replies:  \n     _\"Please upload the candidate profile file before sending the message.\"_\n3. **Extract Candidate Profile**  \n   - Downloads the attached PDF from Slack  \n   - Uses `Extract from File` to parse the resume into text\n4. **Profile Analysis (AI Agent)**  \n   - Sends the resume text and message to the `Profile Analyzer Agent`\n   - Identifies:\n     - Candidate name, email, and summary\n     - Applied position (from message)\n   - Looks up the **Job Description PDF URL** using Google Sheets\n5. **Job Description Retrieval**  \n   - Downloads and parses the matching JD PDF\n6. **HR Evaluation (AI Agent)**  \n   - Sends both the **candidate profile** and **job description** to `HR Expert Agent`\n   - Receives a summarized **fit evaluation** and insights\n7. **Output and Logging**  \n   - Sends evaluation result back to Slack in the original thread  \n   - Updates a **Google Sheet** with evaluation data for tracking\n\n## **How to set up**\n1. **Slack Setup**\n   - Create a Slack bot and install it into your workspace\n   - Enable the `app_mention` event and generate a **bot token**\n   - Connect Slack to n8n using **Slack Bot credentials**\n2. **Google Sheets Setup**\n   - Create a sheet mapping `Position Title → Job Description URL`\n   - Create another sheet for logging evaluation results\n3. **n8n Setup**\n   - Add a **Webhook Trigger** for Slack mentions\n   - Connect Slack, Google Sheets, and GPT-4 credentials\n   - Set up agents (`Profile Analyzer Agent`, `HR Expert Agent`) with appropriate prompts\n4. **Deploy & Test**\n   - Mention your bot in Slack with a message and file\n   - Confirm the reply and entry in the evaluation tracking sheet\n\n## **Requirements**\n\n- n8n (self-hosted or cloud)\n- Slack App with Bot Token\n- OpenAI or Azure OpenAI account (for GPT-4)\n- Google Sheets (2 sheets: job mapping + evaluation log)\n- Candidate profiles in PDF format\n- Defined job titles and descriptions\n\n## **How to customize the workflow**\n\nYou can easily adapt this workflow to your team’s needs:\n| Customization Area       | How to Customize                                                                 |\n|--------------------------|----------------------------------------------------------------------------------|\n| Job Mapping Source       | Replace Google Sheet with Airtable or Notion DB                                 |\n| JD Format                | Use Markdown or inline descriptions instead of PDF                              |\n| Evaluation Output Format | Change from Slack message to Email or Notion update                             |\n| HR Agent Prompt          | Customize to match your company tone or include scoring rubrics                 |\n| Language Support         | Add support for bilingual input/output (e.g., Vietnamese & English)             |\n| Workflow Trigger         | Trigger from slash command or form instead of `@mention`                        |"
