It depends on whether you are a trainee manager or an ordinary part-time employee
1 If you are an ordinary part-time employee, it is very important to go to the restaurant you want to go to and ask the manager on duty for a resume and fill it out, especially the working hours you can provide.
2 If the time you provide is exactly what the restaurant needs, you will be informed of an interview soon. The main purpose of the interview is to see if you are suitable for the service industry, your service awareness and your previous work experience. You should answer honestly. Then they will arrange time for trial work. Trial work is generally to make you feel complex and see if you are diligent. It will be more fortunate and bitter. The trial work time usually ranges from 4 hours to 8 hours. There is no salary, but catering is provided.
McDonald's is tired. If you are sure to go, you should be prepared.
Part-time job. You can go to the talent network in Beijing and choose part-time job. There will be many choices.
I suggest you find an internship related to your major while working. If not, consider the catering industry. However, the catering industry is very training and you can meet all kinds of people.
Good luck.
