GhostJob

GhostJob is a Manifest V3 Chrome extension that scores job listings for ghost listing risk.

It flags weak signals: stale posts, reposted fingerprints, vague evergreen titles, missing dates, low extraction confidence, and optional company career page mismatch.

What it checks

• Extracts title, company, location, description, posted date, valid through date, application URL, canonical URL, host, and extraction method.
• Uses JSON LD JobPosting first when present.
• Falls back through ATS specific extractors for Greenhouse, Lever, Ashby, LinkedIn, Indeed, Workday, and generic job pages.
• Rejects normal app or content pages that only match the weak fallback extractor.
• Stores local listing fingerprints to detect reposts or the same listing appearing across URLs.
• Ignores repeated scans of the exact same page so Run does not inflate repost risk.
• Flags old listings at 30, 60, and 90 days.
• Flags inactive or future pool wording like not an active opening, future opportunities, talent community, general application, and candidate pool.
• Optional live checks can search likely company career URLs when the user grants host permission.

Privacy

• Page extraction runs only when the popup scans the active tab.
• Local history is stored in chrome.storage.local.
• No remote server is used.
• Live checks are off by default.
• Live checks require optional host permission and fetch likely company career pages from the extension background worker.
