If you use Outlook for PC, and if a stage consists of multiple interviews, you can choose to schedule all of the interviews at the same time by clicking Schedule All.
You will want to ensure that you have selected Outlook or Outlook for Mac as your Calendar of choice. Please note: If you select Outlook for Mac you must enter the interviewers and firstname.lastname@example.org in Outlook.
Once you have entered the information for all of the interviews, you will click Download Outlook Invite. This will bring up a separate .ics file for each invite.
Clicking each .ics file will open up the interview invite so you can make any final edits and send out your invitations!
