Frequently Asked Questions

What is a ghost job?
Ghost jobs are listings that companies post with no intention of filling. Studies estimate 22-27% of all job postings are ghost jobs. They waste job seekers' time and create false hope.
How do you detect ghost jobs?
We track two signals: staleness (listings open for 60+ days without updates) and reposting (the same job repeatedly taken down and reposted, a common tactic to appear active). Both are strong indicators that a position is not being actively filled.
How many verified jobs are available?
There are currently 2532 verified active positions. This updates daily.
