Landing a business strategy or operations role at Google is no easy feat. One of the most challenging—and crucial—parts of the interview process is the case study interview.

In this blog, we will dive into how to tackle a Google case study interview effectively, along with some essential tips, examples, and resources to help you succeed.
What is a Google Case Study Interview?
A Google case study interview is typically a 30 to 45-minute exercise where you're asked to solve a hypothetical business problem related to Google's operations or strategy. These problems often mirror real challenges that Google faces. For example, questions may include:
- How can Google increase revenue from enterprise businesses?
- What initiatives could Google undertake to enhance loyalty and retention among small and medium-sized businesses?
- How can Google lower operational expenses in its customer service centers without sacrificing the quality of customer experience?
During the interview, you'll need to create a structured framework to address the case, ask questions to gather information, analyze data, and provide a clear, actionable recommendation by the end.
Google uses case study interviews because they are an effective way to assess a candidate’s capabilities in areas crucial for success at the company. Google case study interviews evaluate five key qualities:
- Logical, structured thinking
- Analytical problem-solving
- Business acumen
- Communication skills
- Personality and cultural fit
Google knows that case study interviews are one of the most reliable ways to measure whether a candidate can tackle the kinds of challenges that come with working for a global tech giant.
The 6 Steps to Solve Any Google Case Study Interview
Here’s a breakdown of the steps to tackle any Google case study interview:
1. Understand the Case
The first step is to thoroughly understand the case presented by the interviewer. Take careful notes and focus on key details such as the context of the problem, the objectives, and any constraints or limitations. If something isn’t clear, don’t hesitate to ask clarifying questions. Ensuring you understand the problem correctly is crucial—misunderstanding the case can lead you to an incorrect solution.
2. Structure the Problem
Once you have a solid grasp of the problem, it’s time to structure the issue. Developing a logical framework is key to breaking down complex problems into manageable chunks. You can use frameworks like SWOT analysis, Porter’s Five Forces, or a custom approach tailored to the specific case. Taking a few moments to organize your thoughts before diving into analysis is completely acceptable and even recommended.
3. Work Towards a Solution
Start solving the problem based on your framework. In a candidate-led case, you'll decide where to begin your analysis. You might choose to start with market trends or customer needs, depending on the case. For interviewer-led cases, the interviewer will guide you on where to begin. As you explore different areas, always explain why you’re pursuing certain avenues of inquiry.
4. Solve Quantitative Problems
Most Google case studies will involve some form of quantitative analysis. This could include calculating profitability, market sizing, or other data-driven metrics. The key is to articulate your approach before you start doing the math. Lay out the steps for solving the problem, and then execute the calculations. This shows the interviewer that you are both organized and thorough.
5. Answer Qualitative Questions
Qualitative aspects are just as important in Google case study interviews. You might be asked to brainstorm ideas, evaluate a business decision, or suggest new strategies. The trick is to structure your answers clearly. Whether you're discussing product improvements or competitive strategies, make sure you categorize your ideas and back them up with reasoning.
6. Provide Your Recommendation
The final step is to deliver your recommendation. Focus on the key points and summarize your findings in a concise and clear way. Avoid getting bogged down in the details you’ve already discussed. Instead, deliver a compelling solution, supported by the analysis you’ve done. You can also discuss next steps, acknowledging any areas you were unable to explore fully during the interview.
