IT people are generally more casual and casual. Unless you need to work in an office building or other places in the future, if you go to the factory for an IT interview, you can wear a decent shirt and pants. If IT is an IT interview in an office building, you'd better wear a suit. But the IT salary of office buildings is very small. We generally have a saying that you make me uncomfortable in a suit and tie, and you have to make it up to me, otherwise there is no discussion. Colleagues go to work casually, sometimes wearing hole shoes and cultural shirts. We are the IT department of an American-funded company, and we hope to help you. Finally, if you wear a suit and tie, you don't want to do our business.
