1. Master doesn't teach you much, largely because he still has a lot of work to do and doesn't have much free time to pay attention to you, but wants to arrange some work for you to kill you. In your name, it is actually to let you develop yourself. Their work experience is accumulated over time, which is not easy. Many teachers will be worried and give you their own experience. If you study in the future, it may threaten his position.
2. Due to lack of experience and experience, there are many new people in the workplace, who are low-minded, high-spirited, unrealistic and modest. This is a common problem of many people. As an old man, I meet too many people every year and will never take you seriously. I think self-righteousness will kill you, so you should also reflect on your attitude. It is very likely that the teacher taught you to do voluntary labor. The boss also asked him to take you because of his qualifications in the company. No extra reward will be given to him, so the teacher's enthusiasm is not high.
3. Some teachers are willing to teach new people, but they also want to see what the basic qualities of new people are, and whether they can think and learn actively and solve problems independently. So, he will ignore you for a while and see how you behave. If you want to ask Master, you must blink your eyes and ask him when he is free or in a good mood, and make good use of some free time, such as having lunch at noon and smoking together.
Many times it is impossible for a master to teach you personally, but his daily work is where you study and observe. Your master came step by step, so don't always think about enjoying success. Through observation, you can think about some empirical logic by yourself, and then you can verify it. The experience gained through your own thinking will be deeper and easier to understand than what others tell you directly.
