There is no system, and policies can change at any moment. Those who cannot accept the system are semi-forced to resign. Internal infighting is severe. When problems arise, people do not solve them together; instead, they stand by and watch, then step in after something goes wrong to showcase their own superior abilities. Senior management, supervisors, and even senior engineers have strong subjective biases and are prone to judging a person's work performance and attitude based on first impressions, age, and habits. The company is still in the development stage, and not a single manager is willing to work for the company's future; they only want to secure a place for themselves. Senior managers use cameras to monitor employees' every move (even when they are on leave) and report them for violations; the primary purpose is not employee safety.
