How to talk when you meet the leader for the first time

Understand your leader's personality and usual way of thinking first. If he is the kind of person who likes to hear good words, you should beautify your language on the basis of facts before you speak. If he is a pragmatic person, don't talk so much nonsense, just answer whatever he asks. In short, observe your words and feelings and don't be nervous. Just deal with it calmly. Speaking can show your ability to do things and your thinking, so remember to speak coherently and with standards.
