There are three categories of professional employment: hardware, software and signal. The hardware is to do fpga and design chips. Software is to write code and rob the computer of its job. I don't know much about signal processing. Probably the spreading direction of ECE abroad. We should learn the course of signal and system and communication principle well. There are many difficult courses, such as analog electronics, high-frequency electronic circuits and microcomputer principles.

Data structures outside the major, big things and engineering mathematics are also very supportive. In addition, hands-on courses, various experiments and small semesters are also very troublesome. Often can't find the problem, the teacher can give little advice, and 80% depends on self-study. Never learn to communicate. If you are not good at math, it will be very painful. Communication course is a bit complicated, but after learning it, it is found that it is complicated but not refined. I hope my answer can help you.
