Case Study Question:

☛ Listen to the introduction - Do not think ahead to your answer(s).
☛ Ask 1-2 clarifying questions, if necessary - Begin to formulate a hypothesis in your head, and test if they are reasonable. While asking these questions, you buy yourself a few moments to postulate.
☛ Do not ask for every piece of data. Some interviewers will try to overload you up front with meaningless data. If you ask for it, you may get it, but later find it irrelevant.
☛ Take notes - Some suggest this is a faux pas, others think it is a great idea. Ask the interviewer if you need to take notes. Keep in mind that every real consultant, in real life, will almost without fail takes notes in an interview. If you can keep track of all of the minutia in an hour long client interview, more power to you.
☛ Structure the problem - i.e. begin to fit the problem into one of the frameworks.
