Optimize Hire provides short, but highly predictive pre-employment tests that help small and large businesses select candidates who will perform better and stay in jobs longer. The assessments are developed with the assistance of researchers at the Wharton School of the University of Pennsylvania.

Greenhouse Recruiting’s integration with Optimize Hire allows candidates to take the Optimize Hire pre-employment test and have results pass back to the Greenhouse interface, where hiring managers can then use the scores to make a hiring decision. In this article, we will cover how to:
