Start with your direction.
Think about the work you want to do, the experience you want to use and the locations you are considering. A clear direction helps make the conversation more useful.
Make your experience easy to understand.
Bring an up-to-date CV and be ready to discuss your recent responsibilities. Specific examples of the work you have done are more useful than general descriptions.
Bring your questions.
Ask about the role, the process and any requirements you need to understand. Keep a note of what is agreed and which questions still need an answer.
