The system they use is rather strange; I've never seen it before, so it's probably self-developed. Below are the programming questions: A piece of code related to multithreading. What is the output after running it? This is very simple; anyone with basic programming skills can answer it correctly. A string with a fixed pattern (described in the question). You need to check if the string matches this fixed pattern. It mainly contains numbers and characters. Also very simple. The rest are some behavioral questions, but they lean towards engineering behavior—scenarios you'd encounter in real work, such as explaining a technical article or report to a non-technical person.
