Received the notice of Jiangsu Mobile Campus Recruitment Interview. I wonder if I have to wear a suit to the interview?

It's best to wear a suit to show respect for the interview.

Give you a little advice, because suits have a lot of manners. If you want to wear it, I suggest you look for relevant etiquette knowledge online, such as how to match shoes and socks, or other small details, otherwise it will be self-defeating and leave a bad impression on the examiner.
