I have written a written test, and Zhang Ping's group has a separate written test in its own group, which is rich in content. At that time, I took an examination of probability, statistics, communication system principles, digital signal processing, digital counters, analog triodes and C and C++. In fact, the exam is relatively wide, so we should pay attention to the foundation. In addition, there will be an English interview. At that time, we talked with the interview teacher in pairs and translated a document, not majoring in communication. English questions are easy to ask the direction you are interested in. Generally speaking, the planning experience of the questions that students have done in the past is to calm down and relax, think for a few seconds before answering. Wish you success!
