It is definitely not appropriate to go directly to the company to find it. If you want to go, people won't let you in at all, so don't say you don't have a chance to interview. I don't think you'll get a chance in the future. I suggest you look at the website of that company first. This is official website from your favorite company. See if their company has a recruitment section. Many companies have human resources sections on their websites. You can directly submit your resume to this company. Or you can go to a well-known recruitment website. If the company publishes recruitment information online, it means that the company must have employment needs. If there is demand, you can call their company directly to ask. General recruitment website companies will leave contact information. It's better to call than to send your resume directly online. Maybe you touched them and let you come for an interview directly.

My friend upstairs said that if you know the telephone number of the human resources department of the company over there, you can call and ask about your situation briefly, but this is not as good as what I said above.
