Disconnections are often due to your internet connection. Your interview is still available to complete. Follow the link in your invitation email, or the steps you initially took, to access your interview again.
If you were disconnected in-between answering questions, then you can simply resume your interview. You will go to the next question in the interview; your previous answers were safely saved to HireVue.
If you were disconnected while answering a question, your question has most likely been submitted. When you enter the interview again, you will go to the next question in the interview. There is not a way for this question to be reset. We recommend finishing the interview and then contacting the company you applied to about the disconnection you experienced. They will be able to send you a retake for the interview if they feel it is needed.
Because HireVue provides support for the interviewing platform, but have no involvement in the actual hiring process; we do not have permission to provide another interview for you.
