If a campaign has already been created for the quiz you want to make a campaign for you can copy most of the settings from the preexisting one to cut down on the time it take to make the new one. You will want to clone over creating a new campaign from scratch if possible to cut down on the potential of entering incorrect settings.
Go to the share tab and scroll down to find the Email Campaigns and Source Tracking section. Copy the old campaign by clicking on the two pages symbol marked in the image.
Go into the settings tab and change the campaign name to the name of the prospective hire that this campaign will be for and save the change with the green button in the bottom right.
You are now done with cloning a campaign. For details on sending the new campaign to the potential hire go to the Adding a User and Sending the Quiz Link section.
