Pros
I don't want to consider punctual salaries as a pro. To work is your duty, to be paid is your right.
Cons
If it really does exist the concept of circus in a company, you can find it at Cheil Industries. No job descriptions, no roles, only lies. Today you can be a manager and tomorrow you will be used as a warehouseman, independently from your background and expertise. Don't hope to make a career there inside, unless you are Korean. The biggest risk is to forget how to work, as there inside you just play something unintellegible. There is a huge difference of salary treatment among Korean people and other ethnicities' ones. They will try with all their efforts to keep some money from your settlement, when you leave, as they consider a shame the fact that you're leaving this company and they will get offended like children. It is strong their attempt to make you think as a Korean, as they don't want to accept that they're working in a foreign country. The management is composed by people that don't even know their name, nor why they've been put there.
