What are the experiences of being cheated when looking for a job? That is, when you are looking for a job, you are often fooled by the intermediary and by many factories. This is the most typical routine of intermediary. There is also the company's HR fool you, set your tone during the interview, can you do related work! Also, after the interview, I asked you to go back and wait for the notice, and then it was gone. This is called "casting a wide net and fishing again". The most common thing is that the salary does not match the recruitment, and it is generally low. This is called "high price attraction, low price signing" and so on.
