HackerRank Assessment integration

As a premier technical skills platform, HackerRank is utilized by thousands of global enterprises to effectively discover and recruit elite engineering talent. HackerRank's solution empowers organizations to seamlessly screen, interview, and assess software developers using an expansive library of over 3,000 coding challenges, immersive projects, and collaborative interview tools. Supporting more than 35 distinct programming languages and tech domains, the platform enables hiring teams to accelerate their recruitment cycles. By prioritizing objective, skills-based data over traditional resumes, HackerRank ensures more confident and informed hiring outcomes.

HackerRank integrates with Greenhouse to streamline the candidate screening and interviewing process for recruiters. As a trusted Greenhouse partner, HackerRank uses the Greenhouse Harvest v3 API to power this integration.

The integration allows recruiters to:

  • Send HackerRank test invitations directly from a candidate's Greenhouse profile
  • View test scores and results within Greenhouse without switching tools
  • Send bulk test invites to multiple candidates simultaneously
  • Sync updated assessment scores back to Greenhouse automatically, keeping hiring workflows consolidated inside Greenhouse from application through offer
