If you answer a question with lots and lots and lots and lots of information, and can indicate a number of things:
- You know a lot about the substance
- You are insecure
- You don't really know the answer and try to talk around it
- You will be difficult to work with because it is hard to interrupt you and engage in a dialogue
- You did not understand the question fully and try to make sure to answer any related question
Better to answer that question short and to the point.
