I have very detailed interviews and rate different aspects of a candidate when I do the interview.

Is it OK if I let my feedback and notes be known to them? It is my first impression of them, and if I were were candidate I would be very thankful for the feedback.

Having said that, I know this goes beyond convention. I am OK if he knows what aspects he needs to get better to impress the next interviewer. I'm ok if he knows this, just as long as he's telling the truth I really don't mind him knowing what I felt he was weak in.

What are your thoughts on this?
