You can set up an interview without leaving the candidate — the profile's Events tab schedules it and keeps the whole interview history in one place.
Schedule from the profile
Open the candidate's profile and go to the Events tab.
Click Schedule event.
Work through the schedule dialog — set it up (type, interviewers, location/link), find a time, choose who to notify, and send.
The interview then appears under Upcoming on the Events tab, where you can move, mark, or cancel it. Nothing is sent to anyone until you send it.
