When you signed up, you filled in a lot of work experience, because it would give people a feeling that you are more experienced. If you have no experience, you can write in detail what you have done or just participated in, focusing on the improvement of your ability in one aspect.
In the interview, I feel that I must be calm and don't show off too much. The trees in the forest will be destroyed by the wind, and my subordinates are too lively and difficult to use. It is very important to show your confidence as much as possible and let them know that you are qualified for this job and that you have a mind to analyze and deal with things. In addition, it is also important to show your interpersonal skills. Remember to look the interviewer in the eye and try your best to make them remember you.
As for the departments to apply for, I would like to give you a suggestion, that is, it is best to apply for only one department, because if you apply for two departments, you will feel wavering and not firm when reviewing. If you have hobbies or specialties, it is better to choose a department with specialties. If you prefer to have real power, the office and organization department are better, followed by the community department and the practice department.
