What is the content of the written test for Skyworth Campus Recruitment?

The written test is one and a half hours. First, there are 20 personality tests, which do not count. Then 20 points in English, 2 readings and 2 translations. The readings are all about TVs. One is about the new functions that may appear on TVs, and the other is also about TVs. I forgot the specific content. One of the translations is about capacitors, and the other is about mobile TVs. It is relatively simple, at the level 4 level. Then there is the 10-point verbal reasoning question, which is relatively simple. The remaining 70 points are professional tests. Definition and use of callback functions, what functions provide the same functions as callback functions, writing a function to realize the exchange of two values, how to split and load a hexadecimal number into an array, pointer resource management (a class instance A defines a pointer, Another class instance B calls the pointer of instance A, how to release the pointer), how MiniGUI achieves cross-platform, talk about your views and improvement suggestions on embedded application development, etc. I can't think of a few questions.
