Pros

Not much work to do, so things are quite relaxed. Most employees are introverted and gentle.

Cons

No opportunities at all for personal growth. An outdated organizational culture that doesn’t fit 2025. A strange compensation structure that gives billions of won to a few people. Incompetence of the executives.
