If your organization has scheduled an interview using the Outlook 365 integration, you can reschedule/update the the interview directly from Greenhouse Recruiting.
Navigate to a candidate profile with an interview that needs rescheduling (All Jobs> Job >Candidates). From the candidate profile, navigate to the Stage tab on the On Job panel and expand the stage that requires a rescheduled interview.
Click Update next to the scheduled interview.
From the Schedule Interview page, edit any interview details.
Once the interview details are edited, click Update Interviewers.
Once sent, interviewers (and Greenhouse Recruiting) will be invited to the updated interview. Users will also need to send a separate interview confirmation email to the candidate for the updated interview.
