Pros
Semiconductor engineering is fun. If you like working with semiconductors and are willing to put in the effort to learn new tools and methods, then Micron is a place for you. You need to like the outdoors more than you like bars though. Idahoans aren't bar hoppers, they are more interested in camping/hiking/fishing than big city life.
Cons
Managment is bloated and overweight. This often makes getting things done quickly nearly impossible. There are more than 4 layers of heirarchy in product engineering and development alone. Unfortunately this bloated nature makes it hard to get promotions as well. Also, the DRAM/FLASH/IMAGER semiconductor field has become very commodity driven and suffers high peaks and deep valleys when looking at revenues. Entering a downturn in the economy, you don't want to be involved with this company as you are likely to be laid off.
