It is common to go with a suit unless otherwise specified. However, some companies have these conditions. "Please come in the usual clothes for the interview"
Instead of a suit it is an instruction to "come with ordinary clothes".
You can think that you can go with a private clothes as instructed, but there is also the idea that "suit is better because it is an interview after all".
However, there are not many people who suffer from "Which way should you do" because you also ignore the instructions of the company you want if you go with a suit.
Such a tweet which issued an accurate answer to such "ordinary clothes or suit or problem" has been drawing attention.
What kind of thing is "correct answer" that got rid of company intention such as "come with ordinary clothes"?
