For each candidate profile, both in the list view and on the full profile in the "Activities" tab, you will find an activity history. Here you can see all your activities (project assignments, recruiting status changes, etc.) for this candidate - and also the activities of your team.
This indicates:
- when and by which team member the profile has already been visited in the past, if applicable
requested and received evaluations - conversations and notes already started, if any (by yourself and by the team, if shared).
