The focus of your resume is what social practices you participated in during your school days. What job did you do in the student union? What internship experience do you have? What scientific research projects have you participated in? What competitions have you participated in, etc.

When describing the above experience, you should write clearly about your role or responsibility at that time, what you did and what you achieved. Through this information, HR can preliminarily judge whether your school experience is good or bad, and whether your past experience is consistent with the position you are applying for.

Be sure to control the length of your resume and try not to exceed one A4 page. If it's too long, HR will probably just pass without looking.
