A completion deadline tells one invited candidate when they need to finish by. It's optional. Truffle doesn't set one automatically. You turn it on when you invite a candidate, or add one afterward from their profile. Once it's passed, the link still opens but shows an expired message and the candidate can't continue. You can extend, change, or add a deadline at any time before then, either for one candidate or several at once.
How to change one candidate's deadline
Open your position and find the candidate on the Incomplete tab (or All Candidates if you're not sure where they are).
Click the candidate to open their profile.
Next to the deadline line, click the pencil icon labeled Edit deadline. This works whether the candidate already has a deadline or shows No deadline set.
Pick the new date and time.
Leave Notify candidate by email checked to send them a deadline-update email, or uncheck it to change the deadline without telling them.
Save.
This only changes the deadline. It doesn't resend the candidate's interview link or generate a new one.
Extend deadlines for multiple candidates at once
Go to the position's candidate list.
Select the candidates you want to extend (checkbox column).
Open the More dropdown in the selection bar and click Extend deadline.
Pick one new date and time, then save. It replaces the current deadline for every selected candidate (or sets one, for candidates who didn't have one).
Candidates who've already submitted their interview are skipped automatically since a deadline no longer applies to them.
Resending an invite doesn't change the deadline
Resending an invite or sending a manual reminder is a separate action from editing the deadline. It reuses the candidate's existing invite link and doesn't extend, reset, or otherwise touch their deadline. To give a candidate more time, edit the deadline directly using the steps above. See How do I send a reminder to a candidate?.
The position itself can also expire
A per-candidate completion deadline is different from the position's own application deadline. Positions don't expire unless you set one, but if you do, the position automatically stops accepting new candidates and invites once that date passes — independent of any individual candidate's deadline.
