Public Sector Consulting Case Interview: Complete Guide

Public sector consulting case interviews


If you’re interviewing for a public sector or government consulting firm, expect to be given several case interviews, or case study interviews, during your interview process.

 

A case interview is a special type of interview that nearly every single consulting firm uses, including public sector consulting firms. Examples of firms with strong public sector consulting practices include: Deloitte, Booz Allen Hamilton, Accenture, McKinsey, BCG, and Bridgespan.

 

Case interviews simulate the consulting job by placing you in a hypothetical business situation in which you are asked to solve a challenging problem. These interviews usually last between 30 to 45 minutes. Throughout the case, you’ll be working closely with your interviewer towards developing a recommendation or answer to the business problem.

 

Case interviews are so widely used by consulting firms because they can assess so many of the qualities needed to become successful consultants. An interviewer can gauge your analytical capabilities, business acumen, communication skills, and cultural fit with the firm all through a single case interview.

Essential Public Sector Knowledge You Should Know

 

Public sector consulting is focused on helping government agencies at a local, state, or federal level solve operational or strategic challenges. Public sector consulting may also include helping non-profit entities.

 

There are eight major categories within public sector consulting:

  • Cities and infrastructure: Developing cities and infrastructure that are economically and socially sustainable

 

  • Education: Delivering sustained gains in learning outcomes at all levels of education

 

  • Defense and security: Helping defense ministries, national security, and public safety organizations address their most pressing challenges

 

  • Global public health: Addressing urgent public health challenges and improving health outcomes

 

  • Economic development: Designing and implementing economic development, job creation, and economic growth strategies

 

  • Public finance: Transforming the financial management practices of ministries of finance and government agencies to create new opportunities and growth

 

  • Climate action: Driving technology and economic transformations to reduce carbon emissions and protect the environment

 

  • Philanthropy: Helping foundations, individual philanthropists, and companies amplify their social impact and achieve systematic change

 

Some examples of public sector consulting engagements include:

  • (Accenture) Helping the National Park Foundation develop immersive digital tools to attract younger visitors to national parks

 

  • (Accenture) Working with the Department of Education to improve the experience of taking out and paying back student loans

 

  • (McKinsey) Advancing childhood literacy in Brazil

 

  • (McKinsey) Boosting agricultural productivity in North Africa

 

Before your public sector consulting interview, we recommend that you research previous work that the consulting firm you are interviewing for has done. This will give you a good idea of what types of case interview questions and topics you could get on your interview day.

 

The 7 Steps to Solve Any Public Sector Consulting Case

 

Follow these seven steps to solve any public sector consulting case interview.

 

1. Understand the case background information

 

The case interview will start with the interviewer explaining the case background information. Make sure that you are taking notes while the interviewer is speaking. You’ll want to focus specifically on understanding the context, the company, and the objective of the case.

 

The most important part of the case interview is to make sure you understand the business issue and objective of the case. Addressing the wrong business problem is the quickest way to fail a case interview.

 

2. Ask clarifying questions

 

Once the interviewer has finished giving you the case information, you’ll have an opportunity to ask questions. 

 

While you can ask any question that you want, try to prioritize asking questions that help you better understand the situation and problem. You want to avoid asking questions that are too specific or not relevant to understanding the case situation. 

 

Most candidates ask between one to three questions. You’ll be able to ask more questions later in the case interview if you need to.

 

3. Summarize the information and verify the objective

 

Once you have finished asking your immediate questions, summarize all of the major case information and verify that you understand the objective correctly.

 

In this step, many candidates make the mistake of stating every fact of the case verbatim. Instead, you should summarize the case concisely and clearly in your own words. This demonstrates that you can synthesize information effectively.

 

4. Develop a framework

 

The next step is to structure a framework to help guide you through the case.

 

A case interview framework is a tool that helps you structure and break down a complex problem into simpler, smaller components. Think of a framework as brainstorming different ideas and organizing them into different categories.

 

To develop a framework, ask yourself what are the three to four major questions that you need to answer in order to make a confident recommendation?

 

Many candidates make the mistake of using memorized frameworks and applying them to their case interviews. Interviewers can tell when you are using a memorized framework because not all of the elements of the framework will be relevant to the case.

 

Using a memorized framework reflects poorly on your capabilities because it shows that you cannot think critically for yourself. Therefore, practice creating unique and tailored frameworks for each case that you get.

 

For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks.

 

When creating your framework, it is acceptable to ask the interviewer for a few minutes of silence to collect your thoughts. Afterwards, present your framework to the interviewer.

 

5. Kick off the case

 

Once you have finished presenting your framework, the interviewer may agree with your approach or may provide some feedback or suggestions. Afterwards, it is time to start solving the case.

 

How the case investigation will start depends on whether your case is a candidate-led or interviewer-led case. Most cases are candidate-led.

 

Candidate-led case: In this type of case, you will be expected to drive the direction of the case. You will be suggesting what areas to explore, what analyses to do, and what the next step should be. So, pick an area of your framework to start analyzing. There is no right or wrong area to pick as long as it is relevant to solving the case.

 

Interviewer-led case: In this type of case, the interviewer will be leading the direction of the case. They will be asking you specific questions that you will answer. After each question, they’ll direct you to the next question. For interviewer-led cases, the interviewer will typically kick off the case by asking you a question after you finish presenting your framework.

 

6. Answer quantitative and qualitative questions

 

The majority of the interview will be spent answering a mix of quantitative and qualitative questions.

 

Quantitative questions may have you estimate the size of a particular market, perform some calculations to determine profitability, or interpret various charts and graphs.

 

When solving quantitative problems, make sure that you walk the interviewer through your approach before you begin doing any math. When performing calculations, make sure to talk through your steps out loud so that it is easy for the interviewer to follow your work.

 

Qualitative questions may ask you to brainstorm potential ideas or ask for your judgment on an open-ended business question. When answering these questions, try to structure your answer as much as possible.

 

After answering each question, make sure that you take your answer and connect it back to the overall case objective. How does your answer help you solve the case? How does your answer impact your potential recommendation?

 

7. Deliver a recommendation

 

At the end of the case, the interviewer will ask you to prepare an overall recommendation. It is acceptable to ask the interviewer for a minute to look through your notes before you give your recommendation.

 

Based on the quantitative and qualitative questions you have answered, what recommendation do they collectively support?

 

Structure your recommendation in the following way:

  • State your recommendation

 

  • Provide the two to three reasons that support your recommendation

 

  • Propose next steps that you would take if you had more time

 

After you deliver your recommendation, the interviewer will conclude the case interview. If the case interview was based on a real life project, the interviewer may explain what actually happened in the case.

 

Don’t worry if your recommendation does not match what actually happened during the project. For case interviews, you are not assessed on your answer, but on your process.

Public Sector Consulting Case Interview Frameworks


There are a few public sector consulting case interview frameworks that are useful to be familiar with.


PESTEL Analysis


This framework helps you analyze the macro-environmental factors that could impact the client's organization or a specific policy. PESTEL stands for Political, Economic, Social, Technological, Environmental, and Legal factors.


  • Political: the influence of political institutions, policies, and stability on the organization or policy. It includes factors such as government regulations, political stability, trade policies, tax policies, and potential changes in leadership that could affect the client's operations or objectives.


  • Economic: encompasses the broader economic environment in which the organization operates. This includes elements like economic growth, inflation rates, exchange rates, interest rates, and unemployment levels. Economic factors can significantly impact an organization's revenue, costs, and overall financial performance.


  • Social: considers the cultural, demographic, and societal trends that may influence the organization or policy. This involves factors like population demographics, lifestyle changes, consumer behavior, attitudes toward social issues, and the overall public opinion about the organization's activities.


  • Technological: pertains to the impact of technological advancements and innovation on the organization or policy. This includes factors such as technological infrastructure, research and development, automation, and the adoption of new technologies.


  • Environmental: focuses on the ecological and environmental aspects that could affect the organization or policy. This includes factors like climate change, environmental regulations, sustainability practices, and the organization's environmental impact.


  • Legal: encompasses the legal and regulatory environment in which the organization operates. This involves compliance with laws, regulations, and industry standards, as well as potential legal challenges or changes in the legal landscape.


SWOT Analysis


stands for Strengths, Weaknesses, Opportunities, and Threats. This framework helps you identify the internal strengths and weaknesses of the organization and the external opportunities and threats it faces.


  • Strengths: refers to the internal attributes and characteristics that give the organization or individual a competitive advantage or a positive edge over others. These are the factors that contribute to success and excellence in the context of the situation being analyzed. Examples of strengths could include a strong brand reputation, a skilled workforce, proprietary technology, or efficient internal processes.


  • Weaknessesinternal factors that hinder the organization or individual's ability to achieve their objectives or may put them at a disadvantage compared to others. These are aspects that need improvement or development to enhance overall performance. Examples of weaknesses could include outdated technology, inadequate financial resources, lack of skilled personnel, or ineffective communication within the organization.


  • Opportunitiesexternal factors and situations that an organization or individual can capitalize on to achieve their goals or grow. These are positive elements in the external environment that can be leveraged to create advantages. Opportunities could arise from changes in market trends, emerging technologies, new partnerships, or changes in government policies.


  • Threatsexternal factors and challenges that pose risks to the organization or individual's success. These are elements in the external environment that could hinder progress or damage performance. Threats could come from increased competition, economic downturns, changes in customer preferences, or disruptive technologies.


Policy Analysis Framework


This framework is designed to evaluate the effectiveness and efficiency of existing policies or proposed policy changes. It involves assessing the policy's objectives, stakeholders, implementation strategies, and expected outcomes.


  • Policy objectives: refers to the specific goals and desired outcomes that a policy aims to achieve. When conducting policy analysis, it's essential to clearly understand and define these objectives. This involves identifying the intended social, economic, or environmental outcomes that the policy is designed to address.


  • Stakeholdersindividuals, groups, or organizations that are directly or indirectly affected by the policy or have an interest in its outcomes. Policy analysis involves identifying and understanding the various stakeholders involved, their roles, interests, and potential influence on the policy's development and implementation.


  • Implementation strategiesencompasses the actions and measures taken to put the policy into practice. Policy analysis involves evaluating the feasibility and effectiveness of these strategies. This may include assessing the necessary resources, timelines, and coordination required to successfully implement the policy.


  • Expected outcomesanticipated results or impacts of the policy once it is fully implemented. In policy analysis, it's crucial to assess whether the policy is likely to achieve its intended objectives and whether there are any unintended consequences that need to be considered.


Public Sector Consulting Case Interview Tips

 

Tip #1: Start preparing early

 

Mastering case interviews takes time. Many of the skills and techniques needed to solve case interviews 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.

 

Tip #2: Practice with a case partner

 

Practicing case interviews with a partner is the best way to simulate a real case interview. There are many aspects of case interviews 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.

 

Tip #3: 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.

 

Tip #4: Focus on improving one thing at a time

 

After doing some practice 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.

 

Tip #5: Use a hypothesis-driven approach

 

During the case interview, you should have a hypothesis of what the answer to the case is. A hypothesis is simply an educated guess based on the knowledge that you have. As you analyze data and gather more information, make sure to be constantly changing and refining your hypothesis.

 

There are two benefits to using a hypothesis to drive the direction of the case. One, it ensures that you are focusing on relevant areas that will help you solve or answer the case. Two, by the time the interviewer asks you for a recommendation, you will already have a refined hypothesis on what the answer or solution to the case should be.

 

Tip #6: Be 80/20

 

You have limited time during a case interview to solve the case. Therefore, you won’t be able to cover all of the different areas in your framework and get answers to every single question that you have. Therefore, focus on the most important issues and use the 80/20 principle.

 

The 80/20 principle states that 80% of the outcome comes from 20% of your effort. During a case interview, focus on the most important questions or areas that will have the biggest impact or effect on developing your answer or recommendation.
