Nothing particularly horrible about the place. The current CEO lashes out sometimes but it's not frequent.
Pay is good - "for Busan".
One major issue I have with this company though is that there is no real HR where you can raise issues you face against another employee or your other concerns. You can take it to your head of department or team lead but I can't say any real action is taken against the person you are 'suing'. So, you're unable to take action against overly disrecpectful employees and their horrible actions won't be reflected in their employee evaluation at all. No HR..
