Mastering the Broad Then Deep Framework for Product Management Interviews

Navigating product management (PM) interviews can be challenging, especially when deciding which framework to use. Instead of rigidly adhering to specific methods, it's essential to develop an approach tailored to each question. One effective framework for PM interviews is the "Broad Then Deep" approach. This two-step process is both simple and authentic, making it a versatile tool for various interview questions. Here’s a detailed guide on how to implement this framework effectively.

Understanding the Broad Then Deep Framework

Step 1: Go Broad

Start by listing a range of options related to the interview question. Provide context and additional information for each option. This initial step demonstrates your ability to think broadly and consider multiple perspectives.

Step 2: Go Deep

After exploring various options, select one and delve into it. Discuss why you chose this option, evaluating its pros and cons and the trade-offs you considered. This step showcases your analytical skills and ability to make informed decisions.

Example Application of the Framework

Let’s consider a common PM interview question: "Which Google product do you think will be the most successful in 10 years?" Here's how to apply the Broad Then Deep framework to this question.

Step 1: Go Broad

Begin by enumerating potential candidates:

• YouTube: Video is the future of the Internet, offering a more immersive and engaging experience than text or audio.
• Google Search: The backbone of Google, indispensable for users seeking information.
• Google Photos: With the rising popularity of photos and videos, Google Photos holds significant potential, especially concerning digital privacy.
• Android Operating System: A powerful and rapidly growing OS with substantial global usage.

Step 2: Go Deep

Next, select one option and explore it in-depth. For this example, we'll choose Google Search.

Why Google Search?

• Dominant Market Force: Google Search remains a leader in the search engine market, largely untouched by competitors.
• Competitive Advantages: Despite the rise of YouTube competitors and other platforms, Google Search continues to be integral to users' daily lives.
• Integration and Innovation: Innovations like voice assistance and integration with smart home devices enhance its functionality and appeal.
• Sustainability: While other products like YouTube and Android face stiff competition, Google Search's established presence and continuous evolution suggest long-term success.

In contrast:

• YouTube might face increasing competition from platforms like Instagram, TikTok, and Netflix.
• Google Photos offers valuable privacy features but lacks the widespread necessity compared to Google Search.
• Android competes with iOS, making its long-term dominance uncertain in developing markets.

Concluding this analysis, Google Search stands out as the product with the best chance of sustained success over the next decade, supported by its market position, innovation, and integration capabilities.

Benefits of the Broad Then Deep Framework

• Structured Thought Process: This framework helps organize your thoughts, ensuring you cover multiple options before focusing on one.
• Comprehensive Analysis: By considering various possibilities and then delving deeply into one, you demonstrate thorough analytical skills.
• Clear Articulation: This approach allows you to articulate your reasoning clearly, showcasing your decision-making process effectively.

Using the Broad Then Deep framework can significantly enhance your responses in PM interviews, making your answers both comprehensive and insightful. By practicing this method, you'll be better prepared to tackle a wide range of questions and impress your interviewers with your analytical prowess.
