Once you've hired somebody, you can convert them from a candidate into a member of one or several teams. This way they'll appear in the team reports.
Find the candidate's report (within the Teams & reports tab). From the candidate's report page, click the "Convert to team member" button. Done! The candidate has now become a member in all of the teams they were linked to.
They will be able to see the team reports and create teams if an admin has given them permission.
