# How to prevent duplicate invites?

If you accidentally invite a candidate who has already been invited:

* **Single Invite** 
A popup will appear alerting you of the duplicate invite. If you still wish to proceed, click **Invite Anyway**.
|| A candidate who has already completed the assessment cannot retake it, even if re-invited.

* **Bulk Invite** 
Duplicates are automatically detected and filtered out. If the uploaded file contains a candidate who was previously invited, a popup will appear notifying you of the duplicate.
