Case study questions may seem like a complicated process left to the business schools and consulting houses, but they can be as simple as summarizing a complex situation you faced and seeing how the candidate responds. Provide an overview of a recent situation you or your company faced and test the candidate's ability to identify and articulate a solution on the fly. Perhaps more important than the solution the candidates develop are the questions they ask. They won't have critical details or background on the problem, so observing how they gather information and begin to break down the problem is the most interesting aspect of case-style questions.
