The first is the internship during school, which is also the practice of all college students. However, let's take a look at how most people describe the internship, just talking about the time, internship unit and internship work, and few people will describe the specific content. To this end, we can make a more in-depth description here. The key is to use your hands and brains when you practice, instead of just moving your eyes and watching like ordinary people. You can find any job to show these two points. For example, when you are an intern as a surveyor, you know how to choose a measuring point, how to improve the accuracy when measuring, how many times a point needs to be measured, the geographical location and the purpose of this measurement. Don't go too far, be comprehensive. Explain in an all-round way that you actually measured it, not watching the master of another unit measure it there. If you haven't really practiced, it's hard to say everything inside.
Secondly, it is based on personal life background, such as you grew up in a smelter, what does your father do in the unit, and then learn something from him when you have time. This is also an exercise, which can let you know a lot. Also, you can go to the shop opened by relatives and friends for help on weekends, even if it is not many times, but you know something related, you can add it.
