Do faculty hiring committees inform the candidates of the results?
My own experience was that whether and when a response came appeared to be exceedingly arbitrary.  Some places gave a rapid "no", others gave a "no" after many months (one after more than a year), and some never said anything at all.  I have heard of similar experiences from other people.

I have not been able to discern a pattern of which organizations are likely to fall into which category, and also know that different people seem to have different experiences with the same organization, presumably based on who is running the committee in a given year.
