Lenovo’s salary is so good, why is it always recruiting workers?

Unreliable, recruiting under the banner of Lenovo, but in fact the employees signed a labor contract with the company, and the treatment is not good at all. Moreover, the interviewer's attitude of coming as soon as he is called and leaving as soon as he is called makes the interviewer make several trips in vain, and finally uses the meeting as an excuse to let the interviewer go back. The work efficiency is extremely poor.
