I have to admit, I was forewarned about working at Disney, and I didn't take it seriously. It's as bad as you've heard, and worse. Substandard pay, long hours, little to no advancement opportunity, incompetent leadership, and petty infighting are the "culture". They don't want top talent, they want "fan-boys" that drink the Disney Koolaid.
The ONLY benefit of working at Disney is that it looks good on a resume, and will probably help land you interviews for other opportunities.
