Detect Duplicate Job Candidates from Gmail to Slack via Sheets

This n8n workflow streamlines HR recruitment by monitoring Gmail for emails labeled 'applicant', extracting candidate details like email, phone, name, and role via regex, then checking against a Google Sheets database. If a duplicate is found (by email or phone), it instantly notifies your Slack channel; otherwise, it appends the new candidate's info to the sheet for easy tracking.

Benefits include massive time savings for HR teams manually sifting resumes, reduced errors in candidate tracking, and seamless integration across Gmail, Sheets, and Slack. Ideal for startups, SMEs, or any team handling high-volume applications via email without a full ATS.

Use cases: Automate resume collection from job postings, prevent double-processing applicants, centralize candidate data in Sheets for analysis, and keep recruiters alerted in real-time via Slack. Customizable for different labels, fields, or comparison logic.

Setup is straightforward: Connect credentials, set Sheet columns (name, email, phone, etc.), input IDs for Gmail label/Sheet/Slack, and activate. Requires n8n, Google Workspace, and Slack permissions.
