Do your homework
You'll most likely be given the names or at least the job titles of the people you are due to meet. Look them up on the company's website and on social networking sites. Try to figure out what makes them tick. Which are the most important functions in the company? For example is it a sales-led or an innovation-led company?
Prepare examples from your work history which demonstrate skills and attributes which will be deemed important to each of the people around the table.
