HackerRank for Work user accounts is assigned any one of the two profiles: Recruiter or Developer. Your HackerRank account's Company Admin assigns one of the above profiles to your user account based on the activities you are required to perform in the application.
To be able to send Test email invitations to Candidates, your user account must be assigned to the Recruiter profile. It is recommended that you contact your company's HackerRank account Owner to verify that your user account is assigned to the Recruiter profile.
Once you log in with the Recruiter user account, you will be able to invite Candidates to Tests.
