From the roles page, each job role has it’s own tile. You can see a quick overview of the number of invites and applicants who have completed their interview.
Click on this line in the tile to review the next candidate (ordered by oldest interview you have not yet reviewed).
You can easily navigate to the next interview by clicking next or previous.
Alternatively, from the shortlist view, hover over the name and click the view button on the left hand panel, or the review button on the main shortlist panel.
