I went to the interview the day before yesterday, and HR told me that their promotion there was particularly fast, saying that she came in July last year, and now she has been promoted to level 4 and worked as a department manager. But he also told me that the company's employees are particularly mobile or something. I don't think it's very reliable anyway. The management mode of each sales office is also closed and militarized. Employees go to work after eight o'clock in the morning, eat and live together, and have little contact with the outside world.
