Resume can be divided into four modules: basic information, educational experience (if you don't have much advantage, you can put it last), internship experience and self-evaluation.
The emphasis is on internship experience. The description of internship experience should include not only the contents of the work done, but also the results of the work. You can write according to the star rule.
Self-evaluation should not be c+v, but should highlight one's own advantages and write a summary of work experience.
