This is gold

Corp America companies don’t do exit interviews often anymore. You have to be at a high level for them to even care about the reasons why you leave.If you want to give constructive feedback, then type up a physical letter, and get it to your Sr Sr manager, anonomysly. Do this way before you quit so it doesn’t look…

I have interoffice mailed confidential and ananamous letters to Sr management with constructive criticism. That actually has worked to make improvements.

This advise is spot on. In a utopia the suggestions from the author are awesome; however they are not value added in reality. If you work in a small industry, or are well known then saying anything in an exit interview is damning and will burn you in spades.
