How do girls dress for job fairs in universities? Can I wear jeans? Do we have to wear high heels?

College job fairs are generally more casual, but you can dress neatly and cleanly, just wear light-colored clothes.

If you go to a big company for an interview, you'd better wear a formal suit. This will leave a very good impression on the examiner.

Most importantly, it's best not to interview at peak hours before interviewing any company you want to go to. Many interviewers will be very tired, and fewer people will have a good interview effect. You can pick some unknown companies for an interview first, instead of going to their company, but let yourself get into the state faster. It will be of great help to your subsequent interview. Answer questions according to the actual situation during the interview. When you are asked any questions at the end of the interview, be sure to say yes. Salary or something. You want to know.

I wish you success!
