As you know from the above, the company does not recruit new people all the year round, and it does not need training. The company's high-quality talents and even middle and senior leaders need training. The only difference is the different training course system. Newcomers pay more attention to induction training, high-quality talents pay more attention to professional skills training, and middle and senior leaders pay more attention to leadership.
As for training from external or internal channels, this is another story. In short, learning is endless. Only by mobilizing all employees to acquire more knowledge and skills through training can the company develop for a long time.
I hope the above answers are helpful to you!
