Pros
There is a chance for great camaraderie if you're in the right group. The company is respected in its field and looks great on paper. The team I was in was a well oiled machine until a new manager came in and changed everything, now they are just limping along and all looking to get out (or for the older ones, make it to retirement under the radar). Nice cafeteria. Train shuttle. Nice campus on the water.
Cons
When Gartner was good, it was great. Now it's too big for its britches and really poorly managed. New management keeps coming in to clean house and not for the better in most cases. Somehow many of the ineffective dinosaurs remain. I have seen people transform from pleasant coworkers to slimy snakes who will do anything to desperately hang on. They keep cramming people into desk spaces that get smaller and smaller. The vibe definitely changed there from a place that cares to merely keeping up their image on sites like this. I went from seeing people truly love their jobs to crying at their desks or being afraid of being let go constantly. There are intense politics and backstabbing is rampant. It's tough to watch but the shameless brownnosers always win there. I really don't know how it keeps winning Best Place to Work awards - I think a lot of the millennials in Fort Myers think it's awesome because they are new to the working world and it's a lot of fun (but yes, hard work) in their sales groups.
