Pay attention to your dress and mental outlook, and make drafts of some simple questions in advance, such as introducing yourself, why you chose your own industry or company, where you went to school or worked before, what you gained and learned, etc. The most important thing is not to be nervous, to be natural and orderly; Don't be too talkative or too boring, as the case may be. General interviews are basically these, and they are all very casual. Ask if you need to bring any documents before you go, just in case.
