When and if your client ends up becoming a candidate, you will need to create an applicant/talent profile for them. Creating an applicant/talent profile rather than "converting" their contact profile to an applicant/talent profile ensures that the data captured on each profile is segregated. Linking the profiles together provides a quick way for users to first identify that the subject is both a contact and applicant as well as provide a quick link to the contact profile's counterpart.
Start at the contact's profile and elect to edit the social sites widget
When the pop up box appears in the center, select "link to applicant/talent"
Note: That Alicia's applicant profile will have already need to have been created
Your widget will then display the link
As seen in the above image, you can also link a contact with another contact profile. This should be used if your contact moves to another organization and continues to leverage your Recruiting services. In that case, you will want to create a new company profile and create a new contact profile for them first.
Tip: To keep track of which contact profile is current, you can red flag the old contact and green flag the new.
