Most of the questions were either specific to the tool I would be working with and how I would deal with certain situations and how I would approach an issue or a rollout with a client/member. They definitely want you to do your research, be knowledgable about the company and the kind of services they provide. I was applying for the Crimson team specifically so I had read everything I could online about the tools and software they offer. I think that really helped me! One person asked me some case study questions that you can't really prepare for, you're either going to work through them like they want or you're not. Do some research about case study interviews in consulting work and you should be able to get some good examples.
