Of course, generally, you have to submit your resume first when looking for a job, which is a preliminary understanding of you personally. If your personal data is more in line with the recruitment position of a company, I will get in touch with you and let you go to the company for an interview. This is a better understanding of you. It is mainly to test your adaptability and oral career evaluation. As for the written test, it is generally conducted by a relatively large-scale company, which is a process of getting to know you personally. There will be several rounds of interviews in a big company like this one! These are just common job-hunting processes, and the rest vary from company to company. Finally, I wish you an ideal and satisfactory job as soon as possible!
