Once an interview is scheduled, you can confirm the date and time with the candidate by sending an interview confirmation email.
Send interview confirmation email
To send an interview confirmation email, navigate to the scheduled stage on the candidate's On Job tab.
Click Send Interview Confirmation.
From the Availability dialog box, edit the necessary fields of the email. By default, the body of the email is drawn from the Candidate Interview Confirmation Message template.

When finished, click Send Email.
Include calendar files (.ics)
Calendar files allow candidates to add a scheduled interview to their personal calendars via a downloadable (.ics) file. By default, Greenhouse Recruiting includes the calendar files in the intergview confirmation email. You can uncheck the box to remove the .ics calendar file.
Note: If all of the scheduled interviews are back-to-back with no gaps in-between, one calendar file will be attached with the start time of the first interview and the end time of the last one. If there are gaps, multiple files will be added, although Greenhouse will attempt to consolidate them wherever possible.
You can adjust the name of the calendar files by clicking the Edit icon 
.
Once the interview confirmation email is sent, the calendar files will be added as an attachment to the email.
The way the file is displayed for the candidate can vary with each mail/calendar client. Generally, the candidate will need to download and/or add the .ics file(s) to their calendars.
The body of your email will also be displayed in the calendar files, so anything the candidate needs to know should be readily available to them.
Note: Calendar files are not linked to the scheduled interviews in Greenhouse, so making a change to the date or time would require sending update calendar files to the candidate manually.
