Users who have enabled the Google Calendar integration can schedule interviews to calendars where they have appropriate editing permissions.
Note: In order to schedule to a shared calendar, you must have permission to Make changes to events on the shared calendar. For more information on creating a shared calendar, click here.
The scheduling process is exactly the same as scheduling an interview to a personal Google calendar, except you'll need to select the shared calendar from the Calendar Type field.
You can access these options by clicking the Settings icon on the schedule page.
