# How to share invitation with a duplicate candidate ?

Refer to the guides below to learn how to send invitations to candidates across each product:
* [Assessments](https://xobin.crisp.help/en-us/article/how-to-send-an-assessment-to-a-candidate-12cli2k/)
* [XoForms](https://xobin.crisp.help/en-us/article/how-to-invite-candidates-to-fill-up-a-xoform-ib1p4m/)
* [AI Interviews](https://xobin.crisp.help/en-us/article/how-to-invite-candidates-to-an-ai-interview-136q3dz/)
* [Tracks](https://xobin.crisp.help/en-us/article/how-to-invite-candidates-to-apply-for-a-track-1yi3v17/)

If you attempt to invite a candidate who has already been invited, follow the same steps as above. The platform will handle duplicates as follows:
* **Single Invite** 
A popup will appear alerting you of the duplicate invite. Click **Invite Anyway** to proceed.

|| 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. Click Invite Anyway.
