Hi,

You should ask the following questions:

1) Clarify the business model. Ask how the company actually makes the money. For several reasons:

1. Even if you think you understand the business model, you need to make sure that you understand it correctly.
2. Some cases have pitfalls related to a business model (re profitability cases with several revenue streams
3. You need to understand the revenue streams to make a proper structure. E.g. if the case is about oil&gas company which revenues are declining, ask if it is Up / mid / down-stream problem. In this case, defining a revenue stream is critical to setting up the right structure. (At the end of the day it may be the decline of snack sales at the gas stations:). In case of telecom company it may be the problem of the core business (wireless) or non-core (landlines, internet)

2) Clarify the objective. Here make sure that your goal is:

• Measurable
• Has a time-framed
• Has / has no limitations

e.g. Should I invest 100k in this business for 1 year if I want to get 15% return?

3) Ask the questions that will help you build a relevant structure and remove ambiguity.

E.g. in the market entry case ask whether we are entering the country organically or non-organically

!!! Finally - do the recap after asking the clarifying questions. Although most of the case books suggest to do it immediately at the beginning of the interview, it makes much more sense to clarify the situation first and then to make sure that you understand everything correctly.

Best!

The number of your questions shold be inversely proportional to the amount of information you get upfront/in the prompt. For example, in McKinsey style cases you might get so much information upfront, that additional questions would be irrelevant and irritating, you'd come as robotic. In all 12 McKinsey interviews I've had, there wasn't need in additional questions at all, I had enough data to move straight to issue tree.

At the same time, if all you know is that there is a client whose profitability is declining, your questions about business model, product and specific goals are valid. I wouldn't go beyond these 3 questions.
