How to Solve an Arthur D. Little Case Interview


There are generally six steps to solving an Arthur D. Little case interview. Step four and step five may happen in a different order depending on the case you receive, but all the other steps will occur in the same order each time.


1. Understand the case


Your Arthur D. Little case interview will begin with the interviewer giving you the case background information. While the interviewer is speaking, make sure that you are taking meticulous notes on the most important pieces of information. Focus on understanding the context of the situation and the objective of the case.


Don’t be afraid to ask clarifying questions if you do not understand something. You may want to summarize the case background information back to the interviewer to confirm your understanding of the case.


The most important part of this step is to verify the objective of the case. Not answering the right business question is the quickest way to fail a case interview.


2. Structure the problem


The next step is to develop a framework to help you solve the case. A framework is a tool that helps you structure and break down complex problems into smaller, more manageable components. Another way to think about frameworks is brainstorming different ideas and organizing them into different categories.


Before you start developing your framework, it is completely acceptable to ask the interviewer for a few minutes so that you can collect your thoughts and think about the problem.


Ideally, you want your framework to be as MECE as possible. MECE stands for mutually exclusive and collectively exhaustive. You want each element of your framework to have zero overlap with the other elements. Additionally, you want the sum of the elements of your framework to cover all of the important issues or areas of the case.


Once you have identified the major issues or areas that you need to explore, walk the interviewer through your framework. They may ask a few questions or provide some feedback.

3. Kick off the case


Once you have finished presenting your framework, you’ll start diving into different areas of your framework to begin solving the case. How this process will start depends on whether the case interview is candidate-led or interviewer-led.


If the case interview is a candidate-led case, you’ll be expected to propose what area of your framework to start investigating. So, propose an area and provide a reason for why you want to start with that area. There is generally no right or wrong area of your framework to pick first.


If the case interview is interviewer-led, the interviewer will tell you what area of the framework to start in or directly give you a question to answer.


Arthur D. Little case interviews are generally interviewer-led, but you may occasionally be given a candidate-led case.


4. Solve quantitative problems


Your Arthur D. Little case interview will most likely have some quantitative aspect to them. For example, you may be asked to calculate a certain profitability or financial metric. You could also be asked to estimate the size of a particular market or to estimate a particular figure.


The key to solving quantitative problems is to lay out a structure or approach upfront with the interviewer before doing any math calculations. If you lay out and present your structure to solve the quantitative problem and the interviewer approves of it, the rest of the problem is just simple execution of math.


When doing case interview math, make sure to talk through your thinking and calculations out loud. The interviewer should be able to easily follow what you are doing in each step of your calculations. Once you have calculated the answer, explain how your answer impacts the recommendation that you are beginning to form.


5. Answer qualitative questions


Your Arthur D. Little case interviews will likely also have qualitative aspects to them. You may be asked to brainstorm a list of potential ideas. You could also be asked to provide your opinion on a business issue or situation.


The key to answering qualitative questions is to structure your answer. When brainstorming a list of ideas, develop a structure to help you neatly categorize all of your ideas. When giving your opinion on a business issue or situation, provide a summary of your stance or position and then enumerate the reasons that support it.


When you finish answering a qualitative question, connect your answer back to the case objective. How does your answer impact the recommendation that you are beginning to form?


6. Deliver a recommendation


In the last step of the case interview, you’ll present your recommendation and provide the major reasons that support it. You do not need to recap everything that you have done in the case, so focus on only summarizing the facts that are most important.


It is also good practice to include potential next steps that you would take if you had more time or data. These can be areas of your framework that you did not have time to explore or lingering questions that you do not have great answers for.

Arthur D. Little Case Interview Tips


Below are our top ten tips for preparing for Arthur D. Little case interviews.


1. Start preparing early


Mastering Arthur D. Little case interviews takes time. Many of the skills and techniques needed to solve cases can’t be learned in just a day or in a week. Ideally, start preparing for your case interviews at least a month or two in advance to give yourself enough time to learn and practice.


2. Be consistent with what strategies you use


Whichever strategies you decide on using for Arthur D. Little case interviews, make sure that you are consistent in using them. The more you use the same strategies, the better and more comfortable you will get using them. On interview day, you’ll have confidence that these strategies will help you nail your case interviews.


3. Practice with a case partner


Practicing Arthur D. Little case interviews with a partner is the best way to simulate a real case interview. There are many aspects of cases that you won’t be able to work on if you are doing mock cases by yourself. Casing with a partner lets you practice your communication, presentation, and collaboration skills.


4. Keep a list of feedback from each case


You should keep a journal or log of all of the different pieces of feedback you get from your case interview partner during practice. This way, you’ll be able to identify trends and prioritize what improvement areas to focus on. For example, if you consistently receive feedback in each practice case that you need to structure your answers, that should be your top area to focus on.


5. Focus on improving one thing at a time


After doing some practice Arthur D. Little case interviews, you’ll likely have a long list of feedback and improvement areas. Try to focus on improving one thing at a time. Before each practice case, decide on the one thing that you really want to focus on and nail. This will be much more effective than trying to improve everything at once.


6. Make sure you understand the business problem and objective


The quickest way to fail a Arthur D. Little case interview is to answer or address the wrong business problem. Therefore, when the interviewer starts the case by reading the case background information, it is imperative that you identify what is the business problem and what is the primary question you are trying to answer. You should always verify the objective of the case with the interviewer.


7. Ask clarifying questions if needed


Don’t be afraid to ask clarifying questions. You will not be penalized for this. If there is a term that you are unfamiliar with, ask for the definition. If you don’t understand the objective of the case, ask questions to clarify this. If there is important information that you were not able to write down, ask the interviewer to repeat specific pieces of information.


All of these questions will help strengthen your understanding of the case situation and make it easier for you to solve the case.


8. Structure your approach before doing any math calculations


Before doing any math calculations, lay out an upfront approach or structure to walk the interviewer through what you are about to do. Developing a structure will help you avoid making unnecessary calculations or reaching a dead-end. If the interviewer approves of your approach, then the rest of the math problem is simple arithmetic.


9. Talk through your calculations out loud


Talking through your calculations out loud provides two benefits. One, it decreases the likelihood that you’ll make a mistake. Two, it makes it easier for the interviewer to follow what you are doing. If you happen to get stuck or make a mistake, the interviewer can jump in to offer suggestions or guidance. The interviewer cannot do this if you are not communicating exactly what you are doing.


10. Answer “so what?” after every question


When the interviewer asks you a quantitative or qualitative question during your Arthur D. Little case interview, don’t just answer it and stop there. After answering the question, ask yourself: “so what?” How does your answer help you solve the overall business problem? What implications does your answer have for your potential recommendation? You should be tying each answer that you give back to the case objective.
