1) The content is simple. After reading your question, there is so much knowledge and miscellaneous things in the university. I don't understand which language you mainly know.
2) Have a clear goal and directly tell the other person the position you want to apply for, such as Java engineer (don't tell me you are not clear, you have to decide the way to go in the future, can hr help you specify the position)
3, prepare some professional counterparts, writing questions, interviews are helpful.
4. Interview process (reserved for those who are prepared):
As long as you are clear about your post, prepare for your professional knowledge and fight in actual combat, what are you afraid of?
5. Be modest and polite, play with your mobile phone before the interviewer comes in, and pass immediately.
In short, opportunities are reserved for those who are prepared to do some learning and accumulation in their own direction, and they are just displayed during the interview.
