Exit interviews are a signature quest. They need you to sign some NDA so you can't bitch about the reeeeally sketchy stuff your boss did.

If they pulled a guy out of a meeting - his meeting - to fire him, those cruel fucks deserve nothing from me but a glance in my rearview.

My last resignation was via a note added to my file on the way out. I left another job with Friday plane tickets and a go-bag and was starting work on Monday in a new time-zone.
