I didn't see any job positions on the Internet. There should be many jobs in such a big company. Where can I find a job? Can I go to the scene for an interview?

Yes, you can contact the employer directly, and if the other party agrees, you can go directly to the site for an interview. Generally speaking, there are contact information on the talent network. I have only been working for a few months. When I was looking for a job, I used the capital talent network to contact the employer directly. They asked me to submit my resume first, and I received an interview notice the next day.
