Personally, if management really WANTED to know the issues versus having the exit interview serve as a formality, I'd expound on the issues in a calm and organized way. It sounds to me that it would likely take the turn of management just going through the motions, and I doubt I'd say much of anything under those circumstances.
I quit a job 25 years ago due to the high stress level and micromanagement that everyone endured having the longest tenure there at 2 years. The exit interview was an excuse for the Regional Manager to belittle me and tell me I should maybe pursue a diametrically opposed job to this one. My numbers and my attitude were never an issue in the job with this Fortune 100 company. This RM had several connections with hiring managers in related and non-related fields, so if there's the potential for retribution or an a-wipe manager has the ability to put the kibosh on a possible offer, I wouldn't say anything that didn't create a veneer over the situation and just thank them for the opportunity.
