You can view a candidate or lead's history with your company by opening up their HiredScore profile and selecting the "history" tab.

You'll be able to see all of the requisitions that the candidate or lead previously applied to at your company, along with some information about the req (including the hiring team, job level, and location). HiredScore will also flag if a candidate is still active in another req at your company with the red "active" button.

If your company's CRM is integrated with HiredScore, you'll also be able to see if the candidate or lead you're reviewing exists within a pipeline.
