How can we help you?


Requirements: The following integration makes use of the custom application fields feature. Only organizations with an Advanced subscription tier can utilize this integration.

Plum provides organizations with the data they need to make predictive talent decisions with the power of AI and Industrial/Organizational Psychology. By measuring talents such as adaptability, innovation, and communication, Plum hosts the single largest database for quantifying human potential at every stage of the employee journey — predicting successful hires, and informing professional development, strategic workforce planning, and emerging leader capability.

Greenhouse Recruiting’s integration with Plum allows you to build consensus around specific talents that are required for each of your jobs. Applicants will be automatically invited to share their individual Match Scores for each job so that from within Greenhouse you can easily determine who possess the talents required to succeed in your specific job. This is accomplished by:

  • Mirroring jobs having the set of Plum specific stages in Greenhouse to Plum.
  • Aligning your hiring team within Plum on the talents or Match Criteria that are required for each job.
  • Inviting applicants to complete and share the results (Match Score) of their Talent Discovery Survey to application fields within Greenhouse.

Add Plum Stage to Job's Interview Plan

For a job within Greenhouse to be mirrored to Plum, it must have three custom Plum stages in its Interview Plan. Our recommendation is to create a template that contains the custom Plum stages. Click here for more information about how to create a template job. 

Within the template you will need to add three specific stages in the following order (spelling is important):

  • Plum Invite
  • Plum In-Progress
  • Plum Complete

We recommend that the Plum stages are the first stages in your Interview Plan.
