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.

Using the Greenhouse/Optimize Hire integration

Applicant assessment experience

When an assessment is sent, applicants receive an email with a link to begin the test

The Optimize Hire/Greenhouse Integration is set up in a way in which every applicant who completes the Greenhouse application automatically receives an email with a link to take the Optimize Hire Pre-Employment Test.

Optimize Hire can edit the content and branding of this email template to meet your needs.

Completed tests will display any next steps to the applicant.

Review an assessment

Applicant test scores are found in the Candidate tab of each job

Focus on the highest-scoring applicants. Overall score is based on the following factors:

  • Highest possible score: 100
  • Highest scores you are likely to see: high 70s or low 80s
  • Top 25% of applicants: 65 and above
  • Average score: 60

Applicants who score high on the Optimize Hire Pre-Employment Test are significantly more likely to have lower turnover, be more engaged in their work, be more committed to the organization, be promoted, and achieve higher supervisor ratings than low scorers.
