1⟩ Tell me do you have any questions?
It is common for this question to to be asked every time, and you should have questions ready. By asking questions you are able to show that you have enough interest to do some research, and that you want to learn all that you can. You should limit the questions to no more than three or four.
You can try asking questions that focus on areas where you can be an asset. Other options include asking about what your position would be, and how fast they expect you to become productive. Also, asking about the next step in the process and when to expect to hear about the position.
