Pros
Great location and cool work if you're interested in the field of economic development or in conference planning. Colleagues are some of the nicest people you'll meet. Some of my former colleagues are friends I'll keep for the rest of my life!
Cons
The CEO is god awful. I mean just god. Awful. Here are the extent of his staff management activities: 1. Demand a specific (and usually unachievable) outcome and then express your dramatic disappointment that employees didn't achieve this desired outcome OR (this one is his favorite) 2. Demand specific outcomes and then swoop in at the last minute and 'save the day', when all along, the organizational chaos he does nothing about is what meant you couldn't achieve that outcome. Good times. If you would have to report to the CEO, avoid IEDC. If you wouldn't have to interact with the CEO, go for it because most staff is super nice, smart, funny and supportive.
