HackerRank Work integrations and automation

HackerRank Work (HackerRank for Work) runs the technical part of hiring: timed coding tests and live interview pads. Recruiters spend a surprising amount of time on the logistics around it, inviting shortlisted candidates, chasing people who have not started, and copying scores into the applicant tracking system. Those are the steps worth automating; judging the code is still for the hiring team.

The HackerRank for Work REST API (v3) authenticates with an API token generated by an account user. Inviting a candidate means creating a candidate on a specific test with their email, with a flag controlling whether HackerRank sends the invitation email, and it returns a candidate record. That record later carries the invite date, score and a link to the detailed report once the attempt is finished. HackerRank's partner guide also describes scheduling interview sessions through the API.

Respect the data. Candidate reports contain submitted code and personal details, so pass a score and a report link into the ATS or a hiring channel rather than copying full submissions around. The API returns both a standard report URL, which needs a HackerRank login, and an authenticated report URL with an access key built in; share the authenticated one only where everyone in the channel should be able to open the report.

A daily check is usually enough: read the candidates on each test, find those whose score appeared since the last run, record it, and nudge recruiters about invitations that have gone unanswered for several days based on the invite date. Keep the candidate id with each row so a re-invite or a second attempt does not overwrite the first result, and so the same candidate is never posted twice to a hiring channel.
