Pros

Workload is not too heavy and can be suitable for people who prefer a stable and routine job. The salary is relatively good compared with the actual workload. It may be a comfortable place for those who are not looking for fast career growth or major challenges.

Cons

The work culture can be quite toxic and political. There is low psychological safety, and people may not feel comfortable speaking honestly. The organization has too much hierarchy, which makes decision-making slow and unnecessarily complicated. Some managers seem to have limited capability in leadership, problem-solving, and decision-making. Many managers act more like messengers than real decision makers. People decisions can sometimes feel influenced by gossip or personal opinions rather than clear data and fair criteria. There are also concerns about bias in hiring or internal selection, such as age, education background, or other factors that may not directly relate to performance. The company also seems to overhire in some areas and still relies heavily on manual work. IT systems and processes are inefficient, duplicated, and create unnecessary extra work. Accountability is not consistent. In some cases, senior people may appear to be treated differently when issues happen.
