If and when you want to send manual reminders to those that haven't yet finished their interviews, you can do so by selecting the "Remind Group" option on your Tribal Layer Task. This will e-mail everyone in that task that has not yet completed their interview.
Note that this is capped to one e-mail every 24 hours, and explicitly shows when the last e-mail was sent too.
Automated Reminders
Automated reminders are sent out at particular intervals between the time you create the interview request through to the deadline you have set:
Initial Request: Sent when you first create the Interview task.
Halfway: Triggered at the halfway point between the "Task Created" date and the "Deadline"
3/4 Mark: Triggered once we are three-quarters of the way from the time the interview was first requested to the deadline set
Day Before Deadline: 1-day before the set deadline another reminder will be sent.
Deadline Day: Sent on the day of the deadline you have set for your tasks.
Overdue: Once the deadline has passed, one final e-mail will be sent informing the interviewee that they're task is now overdue.
We've also put a cap on the frequency of these, so a user will never be e-mailed more than once within a 24 hour period.
