Even with the best structure and consistency, teams still wrestle with manual busywork and too little time with candidates.
Megan, Mega HR’s AI hiring partner, lives inside your Greenhouse workflow as a full-access teammate, not another disconnected add-on. She screens applicants, personalizes outreach, coordinates availability, books interviews, and summarizes conversations; without the need for new tools or process rewrites.
Once connected, grant her access like any Greenhouse user; from there, Megan starts helping immediately.

Adding Megan (AI Agent) to Greenhouse
What Megan (AI hiring assistant) has access to manage in Greenhouse is controlled by what jobs she is added as a Job Admin on.
Follow the steps in this article to invite megan+COMPANYNAME@mega.hr to Greenhouse as a Job Admin: Private.
COMPANYNAME should be replaced with the full name of your company without any spaces.
For example, for a company named Acme Corp, you could use megan+acmecorp@mega.hr. If you have any questions on this, please contact your Mega HR Account Manager or email partner-support@mega.hr.
You may choose to add her to all jobs, or select them individually but Megan must be added as a Job Admin.
Once the following steps have been completed, it’s time to Activate the Mega HR integration:
API key created and shared with your Mega HR account manager
Required Webhooks configured
Megan has been added to one or more jobs as a Job Admin
Your Mega HR account manager then initiates a sync with your Greenhouse company. Once that completes (1 min - 1 hour depending on how much data) you’re ready to go!
