College students' internship should take a formal approach.
The best way for college students to practice is through school channels. General schools will cooperate with enterprises. Although the salary of interns through this channel is really low. However, in addition to college students' own audit, the school will also help to see the payment of wages and the signing of labor contracts. You can avoid many workplace traps.
More "mistakes"
Generally, companies will arrange old employees to bring new people, so that new people can adapt to the environment more quickly. Old employees will tell you how to do the work. On the basic premise of knowing how to do a good job, ask the old employees what to do if they make mistakes, even deliberately. Because making mistakes is human nature. Personally, it is more important to know how to make up for mistakes than to do a good job.
