After you share an interview with a user, you can revoke their access to the interview at anytime.
First, log into Guardify and click "Interviews."
From the Interviews list, find the interview that you want to revoke someone's access to.
Click the 3-dot menu and select "Share."
Find the user's name in the list of shares that you no longer want to have access to the interview, and click the minus sign to the far right of their row.
Click "Save." This user will immediately lose access to the interview.
