That depends on you. You’ve got to use your thinking cap. Also, that’s why you have a team there with you. Remember, everyone sees things different, where you might see something blue, another may notice the number of something it has. So everyone has something to bring. Also, no trivial knowledge will be needed for anything, if there is a bit of information that you would need, it will be provided to you in the room somehow. Basic math is probably your best pre-requisite, anything more than that, we’re pretty sure you’re over-thinking it.
