# Guides GH automation how does it work

## Send automated emails with self-scheduling links

[**How is the automation triggered and what will happen?**](https://www.loom.com/share/9cc4ed4115354876941a6939bf13bca5)

The automation is set per job role and per interview stage. Once a candidate moves into the automated interview stage, they will receive an automated e-mail invitation with a scheduling link of the respective interviewer(s).

The system will look into the interviewer(s) available (free) slots in their regular calendar and share those with the candidate.

When the candidate chooses a slot, all attendees will receive calendar invitations for the interview.

**How will the automation know which interviewer to select?
**
In most cases this will be chosen based on the [interviewers in the interview plan in Greenhouse](https://www.loom.com/share/fafb37c488c14d91bfa25233d8845be1?sid=aaaa8838-492a-492f-a3fa-bfce05e574ed) (not the hiring team).

There are two ways that the correct interviewer(s) scheduling link can be identified to sent to the candidate:

- Greenhouse default interviewer (this will be in most cases)

- One interviewer

- Two or more interviewers where all should attend

- Two or more interviewers where one of the pool should attend

- Cronofy interviewer template (link to setting up interviewer template)

- Interview limits needed to be applied to interviewers.

- Complex interviews e.g. 2 people from a pool should be selected
