1. The school and the company have different schedules. We can be late for school, skip classes, and leave early. But after joining the company, you must follow the working hours of the company, because the company has an assessment system. If you want a promotion or a raise, you should go to work on time. Generally, companies go to work at 8 am and get off work at 5 pm, which is enough time. Don't let yourself sleep late at night, and you can't get up in the morning, which will affect yourself.
2. The nature of work in schools and companies is different. In school, teachers are usually cramming education. Even if you don't want to listen, teachers and family still want you to study, and even force you to study. Whether you understand it or not, you just follow the teacher's rhythm. But when you get to the company, no one forces you to study, and everything depends on your own consciousness. The general supervisor will find you a master. Communicate with the master actively, ask questions if you don't understand, and take notes when appropriate. At this time, taking notes is the best choice. You can watch it later. You should be proactive and good at performance in your work, so that the supervisor can find you, thus enhancing your influence and thinking that you are a proactive person and will leave a good impression on others.
3. Don't engage in small groups. Schools are different from companies. In class, your friends show that you are very popular and your classmates like you. However, if you get too close to your colleagues in the company and start a small group, your supervisor or boss will think that you are starting a small group. Maybe you have some premeditation. The boss hates the existence of such small groups, so you should learn the doctrine of the mean in the office, don't alienate others, but don't get too close to them. Just keep the relationship with your colleagues.
4. Don't talk nonsense. At school, it doesn't matter what you want to say, because it won't hurt others or their interests, but once you enter the job, you should learn to keep silent, do more and talk less. There is a saying that disaster comes from your mouth. At the same time, we should pay attention to how we should speak, and don't hurt the interests of others, otherwise we will make enemies. As for this degree, you should master it slowly in your work.
5. Learn to be observant and work hard. There are many complicated things at work, so we should pay more attention to how our colleagues deal with such things, get in touch with them more, and don't make their own suggestions. Once the interests of others are involved, stop immediately and don't make mistakes.
6. Don't complain and don't get angry. There are inevitably many troubles at work. At the same time, you will meet many kinds of people, and the interests of others will inevitably be involved in your work. Once you touch the interests of others or your own interests, you should hold your horses, don't be impulsive, don't argue with others when you think it's right, learn to be calm, and don't complain about others' bad after solving it. This is impolite to others, and it is also damaging your image. Others will think that you only complain and speak ill of others behind their backs, and you are an unworthy friend or colleague. This is not worth the loss, so remember, impulse is the devil.
These are my personal feelings. There's still a lot to write. Some things still need to be experienced by yourself. With more contact, I gradually get to know them. Good luck in your work and an early promotion. I hope my answer can help you. I wish you a happy job!
