2, the hukou problem, this is hard to say. Not all large enterprises can solve the hukou, and the enterprises that can get the hukou at present are all like this. Central enterprises, North enterprises, other state-owned enterprises in Beijing or high-tech companies (such as Baidu) cannot solve the hukou because they have no national background. If you want to solve the hukou, you need to find a unit with a state-owned background, otherwise it is unlikely.
You'd better ask about their treatment and hukou, which is the most direct. Just ask. All units like direct people, and no unit likes people who beat around the bush.
