Any reply would be good. Even if it's a pre-canned copy/paste. It answers the questions that comes up if you don't hear anything: "did my email not send properly?", "did they miss me?", "are they ignoring me on purpose?" etc.

It takes almost no effort, and shows that you care about the people around you. If someone came up to you and asked you in person, would you ignore them and keep walking?

We respond to all candidates, in all stages.

Now to be honest - we use greenhouse, and their tooling for recruitment workflow is not bad. A decision to accept/reject will always trigger an email. Of course we've templated our own custom responses, but editing the outgoing email before sending is also easy enough.

As for interview feedback, I personally write my interview notes in such a way that if the candidate asks for more detailed feedback, the notes can be pasted pretty much as-is. When the hiring workflow and candidate communication are intricately linked, things are less likely to fall between the cracks. Everyone feels better.
