While it may not be possible to give every candidate feedback after an interview, I've found that doing so can have several benefits, including: 1. It can increase the candidate's respect for you and your organization. 2. It can improve their ability to succeed in future interviews. 3. It can give them a perspective they may not be able to get elsewhere. Give the feedback you think will be most helpful for the candidate. I often liken this to a great football quarterback who throws the ball to a receiver in a way that leads to a catch and the ability to get yards after they make the catch. For example, if the candidate had a fantastic interview but fell short on some primary skills needed in the role, it can be helpful to let them know both aspects. To continue the football metaphor, they would be able to "catch" this pass and take specific action after they do.
