Giving feedback is bad for the companies initially as a lot of biases are exposed when the feedback is reviewed. As in some engineer thinks something a candidate doesnt know makes him dumb. Just because the engineer has worked a lot on that problem and the candidate never saw it. In the longer term, I think its good as even constructing the feedback makes you look at your biases in an objective way and evaluate candidates better. I wish every company I interviewed for would give me feedback.
