How many clarifying questions are appropriate and when should they be asked?

Good question! I look at it in two ways:

First: What isn't clear?

Here, you just want to ask anything you don't understand. Naturally, we want to run away from what we don't know...consultants run towards it!

• Do you understand the context provided? Do I know how the industry works and how they company would likely be operating?
• Do you understand the problem/opportunity they face? Is it clear what they're trying to do?

Second: Use GOBTM

Write GOBTM at the bottom of your page in case you're stumped in part 1.

G = Geography (Where to they operate, where are they looking to go, etc.)

O = Objective (Can I clarify the exact objective of this case. I.e. increase profits by how much)

B = Business Model (Am I clear on how the company makes money and what they sell?)

T = Timing (Over what time frame does this solution/problem take place?)

M = Market (Who are my customers? What market do I operate in?)

Bonus

Fundamentally, you are trying to narrow your framework. You are tyring to ask questions that get you closer to the solution

Bonus 2

Never ask an open-ended/vague question. Try to lead with a hypothesis. For example, don't say "How does this shoe company work?". Rather say "I imagine the shoemaking process involves reviewing wood/leather, cutting/shaping it, sewing/gluing it together, and then finishing it in some way. Is this about right?"

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!

From my point of view, you should ask as many clarifying questions as you need in order to feel you fully understand the client's situation. Any question which can impact the way you think about the problem, and therefore structure it, is important. Examples:

- "What exactly is product X?" - if you don't fully understand what a product/service the company/industry is selling is, you have to ask. it will actually look bad on you if you get halfway through the structure and it becomes clear you don't really understand what we are selling.

- "How exactly does this industry work?" - If you are unfamiliar with an industry and aren't sure how it works, ask about it - e.g. repair parts for cars - does this mean you ship cars to manufacturers, sell directly to consumers, etc.

- "What specifically is the client's objective?" If the objective isn't super clear (e.g. want to return to profitability) clarify this as much as possible. Even if the overall objective appears clear, further clarifying it (e.g. does the client have a specific timeframe in mind.

These are definitely not exhaustive, and every case will have it's own nuances and ambiguities.

As for when to ask, you should firstly clarify the prompt (essentially repeat it back to the interview to make sure you haven't misunderstood anything), then ask as many clarifying questions as you need, and then take a minute to lay out your structure.

Dear A,

Actually it's ok to ask 2-3 clarifying questions you start your case. Sometimes it may take more, depends on what basic information you have.

There are 3 main types of clarifying question which you may ask to fill the information gap before case solving. There are related to the objectives of the case, information about the company and some terminology you're unfamiliar with.

Here are some basic things you need to know before the case:

- about the case objective:

• What is the measurable metric of success?

• What is the time frame?

• What are potential restrictions or limitations?

- about your understanding of the company

•. Business model: How does the company make money? Do they sell directly to customers or do they sell through retailers or partners?

• Products and services: What products and services does the company sell? What benefits do these products and services provide?

• Geographic location: Does the company have one location or are they a national chain? Does the company operate in just one country or do they have an international presence?
  
  - about definition of a term you are unfamiliar with

Most consulting interviews do not require you to have specialized knowledge or expertise in an industry. Therefore, if you come across a term that you are unfamiliar with, it is completely acceptable to ask the interviewer for the definition.

After getting the information about the case, make sure you have all the pieces of it that you need, if you don't then go for clarifying questions.

Best,

André

Hi there,

The number of questions depends on the complexity of the case. For many cases, 2 to 4 are enough.

Good questions at the beginning are related to:

• Clarify goal and constraints of the client
• Understand the revenue model of the client
• Clarify any part of the prompt which is unclear

You should ask questions until these points are clarified and avoid to ask questions related to parts of the initial structure in advance.

Francesco

Dear A,

Actually it'normal to ask 2-3 questions before you start solving cases. I would split all the clarifying questions into 3 category:

1. questions that clarify the objective of the case interview

2. questions about information that strengthens your understanding of the company

• Business model: How does the company make money? Do they sell directly to customers or do they sell through retailers or partners?

• Products and services: What products and services does the company sell? What benefits do these products and services provide?

• Geographic location: Does the company have one location or are they a national chain? Does the company operate in just one country or do they have an international presence?

3. question about definition of a term you are unfamiliar with

Hope ot helps,

Best,
André

I agree with the three categories of questions suggested but would suggest to limit time spend on those to 2-3 mins, depending on the lenght of the answer. If after 2-3 mins you are still asking questions without putting a structure together, then, very likely you are starting to solve the case without a structure in place and that’s not ideal.

hope it helps,

Hi, I'm going to give you my thoughts based on MBB Interviews.

Generally, the prompt is fairly comprehensive and long - if the info isnt in the prompt the interviewer will not normally know it ( except if this is a partner interview and they are doing it themselves atm).

It is fine to clarify points that they have been said, however in my experience when i tried to ask about time frames, hard objectives etc there was no info.

"do we have a time period for achiving this market share---NO"

"do we have a specific financial target as a revenue goal...NO"

"Do we know if this has been experienced by our competitors...NO"

Get my point? By the last question we were both laughing as it clear i had extracted all the info there was and it was time to move on.

SO - my takeaway is clarify 2 or 3 things that have been said, but as for gathering extra new info, you can still ask for it...but dont expect them to tell you anything.

please note - this has just been my experiences, but good to know none the less!

GL!

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.
