Generally speaking, no notification will be given. But just one week does not mean that you have no chance of being hired. There are many companies that are very slow in deciding whether to hire people, and some take a month to decide whether to hire someone.

Especially for large companies, they often reserve in advance, so don’t rush. Pay attention to their website or WeChat account. Generally speaking, they will release company news. If they release such news, it means that you have not been hired.

I have passed the exam now and am already working there. Last year I bought the review materials from Blue and White Deer, which included video courses, past papers, 50 sets of all-real simulation papers, etc. Overall it's very good, you can refer to it for your own reference.
