What should medical students pay attention to when attending campus job fairs?

Don't send the same cover letter to multiple companies at the same time. Some medical students send several "exquisite" self-recommendation materials to different hospitals with the psychological state of "various types and fruitful results". How much of these non-personalized self-recommendation materials will attract the attention of recruiters? There may be only one result-when the waste paper is disposed of. If this happens, even if your interview skills are excellent, it is meaningless for the hospital not to interview you.
