Pros
Solid, stable company. Industry leader. Opportunities for advancement or movement to other positions. Great for sales and marketing or R&D but not much else.
Cons
Overworked and underpaid. Lots of turnover and little training, which means a lot of managers that don't know what they are doing. Too much focus on "the numbers" and stock price, and not concerned about employee happiness. Emphasis is on cutting costs (labor specifically) and not on creating value for the customer. Company does not learn from mistakes, and all decisions are top-down. Does not listen to ideas from below. Very political. Rewards "yes-men" who appease their managers, and punishes anyone with negative feedback (even if it's the truth). Very poor communication between divisions. No transparency. Has major, major problems with IT infrastructure and its proprietary software that is essential to its operations.
