Was flown down to Canberra for the interview. There were about 2 others being interviewed also, but for different areas. Questions focused on intellectual property, scenarios where I had to state whether this "invention" should or shouldn't be patented and why. They also made sure that it was clear that most patent applications are not considered inventive enough to be accepted, so the majority of work is rejecting applications. Also some questions about the wording of patents being important. There was a written component, which had two questions - one was to detail a holiday I had recently been on (I assume this was to test general writing skills), and another one was very strange and not very related to my field "Name a body part that is either permanently open at one end or optionally open at one end, and closed at the other end, that holds liquid and is able to control how much comes out" or something along those lines.
