The main thing is what you know. For people with work experience, the general company first looks at what he knows, whether his major is unprofessional or not, and whether he can do it independently. For example, I wrote:

Hard-working, hard-working, strong sense of responsibility, hard-working, skilled in using CAD software to draw various electrical drawings. Have high voltage electrician certificate and low voltage electrician certificate.

Although I have a college degree, I have been engaged in real estate electrical and power design for 8 years, with solid theory and rich experience. I can independently complete the electrical engineering design of residential quarters and commercial buildings, and have done electrical design of more than 20 residential quarters and commercial buildings (only written some project experience), and my ability is by no means inferior to that of undergraduates. In addition, due to my work experience, I am proficient in electrical equipment and power engineering used in real estate, and I am fully qualified for the position of the company.
