Very simple, targeted writing. For example, if you want to do sales, write down your advantages in communicating with others, including persuading others, instead of writing down what projects you have completed, how many books you have read and how to draw a prototype. In short, we must be targeted. An aimless resume will distract your sister and make her wonder what you really want to do. If you haven't found an internship, you can send your resume online. Good luck.
