Pros
Samsung practically owns the political and social institutions in Korea. This means having a relatively stable job that accords some semblance of taking pride, as long as you turn your head away from all that nonsense going on at Samsung. Because the company and its parent Samsung Group dominates all walks of life in Korea, one can choose to fool others and himself in believing that he is doing something genuinely important. When you tell others you work for Samsung as a Director, most people in Korea will respond with a display of respect+jealousy. No matter how desperate he may be on the inner conscience, one may keep up the fool's game.
Cons
Samsung embodies some of the best and worst features of Korea's business culture. Hierarchy and favoritism, as well as nepotism run to the extreme. Senior management has deeply rotten sense of conscience, and don't feel ashamed. Silos between businesses mean one's peers from other BUs attack for the sake of discrediting competition for promotion. It is a food chain running from the Chairman down a long line of pecking order.
