TSR rules, and the fact of it being a job interview that requires you to show your initiative, means there can't be too much said as a response to you. However, there is plenty of information on here about what resources to use, and it's up to you where you research, and how you demonstrate your knowledge and justify your answers. If you aren't sure or can't find a piece of information, you say what you have found, and its source, or that you don't know.
