(1)First of all, I worked as a XXX in XXX Company after graduation. This job helps me to reduce the burden of my life and also allows me to gain a lot of experience.
(2)Secondly, I directly communicated with professors/teachers, participating in the research/experiment of the subject named XXX when I was in the school, and published the paper of XXX. This research experience helped me to improve my knowledge framework and system (improve my practical ability and experimental skills), deepening my knowledge of XXX major content, and inspire my future research ideas.
(3)In my spare time, I have participated in some forum activities/course training/ lectures/conferences/competitions on XXX major and made some reports related to XXX major. These experiences have broadened my horizon, training my practical skills and made me think about what kind of research I will carry out in the future.
(4)Finally, from my personal point of view, I like the XXX major of your university very much, and I've also paid attention to it in my spare time. I'm looking forward to studying in xxx school. Although my work has helped me reduce the burden of life and given me a lot of experience, my promotion and salary are undoubtedly linked with my education background, and when I encounter problems, I have little time to learn the methods and knowledge to solve these problems, so I want to stop and learn more when I still have learning motivation to cope with challenges.
