If you use Google Calendar, and if a stage consists of multiple interviews, you can choose to schedule all of the interviews at the same time.
Navigate to the candidate's profile and click Schedule All in the appropriate stage.
From the Scheduling for candidate page, click the Settings icon and ensure Google is the selected calendar. If another calendar (or no calendar) is selected, click the Calendar Type dropdown and select Google. Click Save when finished.
Enter the information for each of the interviews, including the date, time, interviewers, etc. Once you have added all information, click Schedule and Continue.
On the subsequent page, confirm the interview details are correct, then clicking Send Invites to send the invitations directly from Greenhouse Recruiting (if you have enabled the Google Calendar integration), or click Open in Google to view and send the invitations from Google Calendar. If you click Open in Google, the invitations will open in new tabs or windows.
If needed, finish sending the invitations from Google Calendar by clicking Save in each. Once you have sent the invitations from either Greenhouse Recruiting or Google Calendar, be sure to send an interview confirmation email to the candidate.
