Not a comprehensive guide but a couple of reflections as I definately improved my answers after several tests (ymmv and may slightly differ for different law firms):
1 Prioritise teamwork, while taking ownership - this means being happy to colaborate, but not unnecesairly sharing responsibility
2 Have your own voice - if you have something to say, say it
3 American firms often want you to be comfortable taking responsibilty
4 Do not bother partners immediately - try figuring it out for yourself first or ask a colleague
5 Remember you are applying for a junior position - this means that you will likely not be talking to the client without a superior asking you to. This also means you will not be telling partners "no" pretty much ever.
6 Be really open to new experiences
7 Be really curious to learn
