Matching a competent job has two implications: One is that someone's comprehensive capabilities can fully meet the requirements of the job. This is the so-called "personal work". The second refers to the requirements of a particular job. Ability and job seekers are well-equipped, so-called "craftsmen". The principle of ability and post-matching means that people's abilities need to match as much as possible with the abilities needed for their work. This match has the meaning of "exactly". In the process of SME development, if a company wants to survive and develop sustainably, it is necessary to emphasize hiring and proactively solve various difficulties faced by hiring. "Matching" is more important than "personal excellence". Some people are in very good hardware and have a high overall quality, but when placed in a particular environment, not only are they unable to perform, but the overall combat effect is weakened and mediocre. Some people are qualified. However, when placed in the right environment for them, the work performance is excellent, it also strengthens the overall strength of the team and achieves the best synergies. Therefore, we consider the principle of matching to be the golden rule of adoption. It doesn't matter if the hires are the best, but the most important thing is the best match.
