Hehe, don't be timid. Remember that everyone is equal. Even if he is in charge now, he has come step by step, so he has experienced what you have experienced, so don't be afraid of his strength or something. After all, they recruit people for the needs of the company. Let me give you some phone skills. I hope it will help you. You can say something like this: "Hello, excuse me, I saw the recruitment information you posted on * * (via, I will tell the newspaper when I see it in the newspaper, and I will tell which website when I see it on the website). I want to apply for the position of * * in your company (or company), and I don't know whether it is full." If the other party says it's full, you can only say excuse me and change to another one. Anyway, it may be useful to leave a good impression on the other party in the future. If the other person says he is still recruiting, you can ask, "When is it convenient to come for the interview? Do you need to bring anything?" Then remember the other party's requirements and go to the interview on time. As for being small, because you are looking for a part-time job, there is no need to worry about the height limit for the time being. Generally, there is not much demand. If you are full-time, some jobs will be limited, but many units look at your comprehensive quality instead of generalizing. Come on, I wish all the best.
