How much feedback do you expect after a job interview?

In hiring staff for my high school, I've never given feedback to candidates, even those I hired. When we decide not to go with someone, I'll send them an email thanking them for interviewing, that the position has been filled and wish them well in their job search. My understanding is often applicants aren't notified they didn't get a position, but that has always seemed pretty cold to me. I feel like they took the time to prepare and meet us, the least I can do is thank them for their effort.

I give no feedback for interviews. I agree with the legal sentiment expressed in this thread as the primary reason for not giving any feedback. However, there is a secondary reason - the feedback isn't that helpful for the interviewee. Generally, when someone isn't hired, it falls into one of the following categories:The interviewee was competent, just not for the field being hired for. In this case, there's nothing I can do to make the interviewee more competent in the field being hired for.The interviewee was generally incompetent. In this case, any feedback would be generally discouraging.The interviewee didn't mesh with the personalities of the group. In this case, I can't provide useful feedback because it deals with something the interviewee can't realistically change. Further, vague reasons not to hire someone like personality are particularly prone to legal liability.The interviewee had no social skills (like, in one instance, insulting one interviewer, who happened to be one of the most senior employees in the room). Similar to 3, this isn't something that can be corrected by feedback.

No feedback. It leaves you open for lawsuits, ESPECIALLY if you're telling them you're not hiring them. Thank them for their time, wish them luck, send them on their way.

I interviewed for a couple of jobs recently where I got zero feedback after the interview. It was a case of "if we're hiring you, we'll call you, otherwise you won't hear anything." I get that organisations only have limited resources, and I wouldn't expect lengthy and detailed feedback, but I do think it's pretty rude to just blank someone post-interview. If you've spent time and money preparing and travelling to the interview, taken time off work, and spent a not inconsiderable amount of time talking to the hiring manager, the least you should be able to expect is a brief phone call to say "we've decided not to hire you, but it was great to meet you and thanks for your time." What I've found is that the more senior the job role, the more likely I am to get feedback after the interview. The jobs where I got no communications were lower-paid entry-level roles where I assume they interview en-masse, whereas when I've gone for higher-level positions I've always had decent feedback. The job I'm in now, I was the only candidate.

Zero. Maybe a general "we don't think you'd be the right fit" or "we decided to go with a candidate with more experience in X." Sometimes a "we thought you were a great candidate, though" when applicable. Anything beyond that would be bizarre and potentially insulting. Not only did you not get this job you wanted/needed, perhaps desperately, but let's talk about all the ways you didn't measure up! It's like dating; it's just not polite to tell someone why they're not being chosen, and it's usually not helpful, especially since once you get to the in-person meeting, it often comes down to intangible things that aren't even flaws. The only exception is if it's an interview arranged through a third-party recruiter, and the recruiter is the messenger. But even then, it's usually not done. I do expect to hear about being turned down. It doesn't always happen, but if you make it to the interview stage they should extend that courtesy. Email is fine, but I've gotten the news over the phone.

I don't expect any feedback, although if it is helpful feedback, I would appreciate it. I would expect to be told that someone other than me is being hired, although that is not something that is always communicated. I expect that news to come in a letter; a phone call means I'm getting hired.

It's been a while, but zero feedback expected. A "sorry, but we've gone with another candidate" was great, but not universally provided.

I expect zero feedback, and I give none outside of the interview process- even if a candidate emails me to thank me, we're not supposed to correspond with them. The only exception I make is is for summer interns/grads fresh out of school who are utterly failing at the interview, and I will spend a minute or two reviewing the areas/work that they are expected to know (ie if your resume says you are a math major, and you can't reason through basic probability that might be a problem), as well as try to cut them off when they go on a long elaborate derails. Some get the hint, and are able to reframe their train of thought and have a better rest of the interview, but many don't.

Agree with the above, the exception being if the position is internal. Then, at my request, I have received some feedback. But I didn't expect it and was grateful to receive it- I considered it a kindness of my colleague to give me more detail about what differentiated the preferred candidate from myself (experience, in this case, plus a bit of politics).
