I applied for a job last year, so I can give you some advice. For a position like a teacher, the interview is divided into written test, trial lecture and interview. The written test examines the ability of specialized courses. If you want to apply for a math teacher, you must have good math skills. The difficulty of written test depends on the grade you are applying for. After that, there is a trial lecture. If you have been a teacher, it's easy to give lectures. Just take out the aura! After the trial, it is the last meeting. Finally, I will ask you if you can accept the class time, because you are often busy at night, weekends, winter and summer vacations. As for getting a high salary, it must depend on the individual. You take more classes and naturally get a high salary!
