In the Application Card View, a new field named Lead Source has been added to a person's card. This field shows the original source where the person found an opening. If you click "[all]," it will show each time and each source where the person was tracked. The initial tracking event will be the one that is shown.
You can also view the Lead Sources in the Action dropdown menu within a person's profile.
This differs from the Referral Source field in that the Referral Source is filled out by the person during their application, or by the recruiter, while Lead Source is automatically filled in by A-Suite's tracking functions.
