The 'Familiarity' Fallacy: Why 'I'm more familiar with it' is a Terrible PM Interview Answer

In product management interviews, especially those focused on product sense or design, you're often asked to clarify scope. "Design a product for airport travelers," a Google interviewer might prompt. A common, seemingly innocuous response I hear from candidates, often with a confident nod, is: "I'll choose the US market because I'm more familiar with it."

Here's the tough truth: that's a terrible reason. And while it might feel authentic to your personal experience, it reveals a fundamental misunderstanding of what a Product Manager does.

The Problem with Personal Familiarity

Think about it from the interviewer's perspective. They're trying to assess your ability to think like a PM. Product Managers make strategic decisions grounded in business rationale, market dynamics, and user needs, not personal comfort zones. When you say, "I'm more familiar with it," what you're implicitly communicating is:

1. Lack of Business Justification: You're prioritizing your personal convenience over any data-driven or strategic reason. Your familiarity doesn't equate to market opportunity, competitive advantage, or user pain points.
2. Limited Strategic Thinking: It suggests you're not thinking about market size, growth potential, regulatory environments, or the company's existing footprint. All of these are critical factors in deciding where to launch a product.
3. Potential for Bias: Relying on personal familiarity can lead to overlooking more lucrative or strategically important markets simply because you haven't personally experienced them.

As we emphasize in Product Simply's approach to making an argument, every assertion, every choice, needs a clear "why." This "why" must be rooted in business sense, demonstrating your insight and analytical rigor, not just your personal preferences.

The Airport Travelers Example: A Missed Opportunity

Let's revisit the "design a product for airport travelers" question. If you immediately scope to "US airports because I know them," you've missed an opportunity to showcase your strategic chops. Instead of demonstrating how you'd apply your product sense to a global problem, you've narrowed it down based on a non-PM criterion.

An interviewer isn't looking for you to be an expert on every single airport in the world. They're looking for your process of making an informed, strategic decision.

How to Provide a Business-Justified Reason Instead

So, what should you say? The goal is to articulate a logical, business-oriented rationale for your chosen scope. Here's how to think about it and what to include:

1. Align with Company Goals (Hypothetical or Real): Consider what the company asking the question might value. Is it rapid user acquisition? Entering a new strategic market? Monetization? You can make an assumption and state it. "Assuming our primary goal is rapid market penetration and testing an MVP, I'd focus on markets with high smartphone penetration and a digitally native population."

2. Market Dynamics & Opportunity: Think about factors like market size, growth rate, competitive landscape, and regulatory ease. "I'd like to focus on the Asia-Pacific market, specifically countries like Singapore and South Korea, as they represent a high volume of tech-savvy international travelers, dense airport hubs, and a relatively streamlined regulatory environment for digital solutions. This offers a concentrated opportunity for initial impact and learning."

3. Leverage Company Strengths: If the company is known for something, weave it in. "Given Google's strength in mapping and location-based services, I'd propose focusing on major international hubs that serve as significant transit points, such as Dubai or London Heathrow. These airports could benefit most from intelligent navigation and real-time information, leveraging Google's existing data infrastructure."

4. Risk Mitigation & Iteration: Sometimes, starting smaller or in a 'safer' market is a strategic choice for learning. "To mitigate risk and enable rapid iteration, I'd initially target a single, high-traffic regional airport in a market with strong tech adoption, allowing us to gather focused feedback and refine the product before a broader rollout. A place like Austin-Bergstrom International Airport in the US comes to mind, known for its innovation and diverse traveler base."

5. Data Availability: If data is crucial, choose a market where it's accessible. "I'll focus on markets where we can easily access anonymized public transportation data and traveler movement patterns to inform our product features, which might lead us to consider European cities with robust data privacy frameworks."

Crafting Your 'Why' Statement

When asked to clarify scope, take a brief pause. Then, instead of defaulting to familiarity, articulate your choice with a clear, concise, and business-driven "why." It might sound something like this:

"That's a great question. To ensure we're targeting a market with significant potential for our product, I'd like to focus on major international transit hubs. This allows us to address the needs of a diverse, high-volume traveler segment and leverage potential partnerships with airlines and airport authorities. Specifically, I'd start with a city like Seattle due to its high density of international connections and demonstrated willingness for digital innovation, allowing us to test and learn effectively. Does that sound like a reasonable scope?"

Notice how this response doesn't just state a market; it justifies it with strategic considerations like traveler segment, partnership potential, and the desire for effective testing and learning. It shows you're thinking beyond your personal comfort and into the realm of product strategy.

Authenticity and Strategic Thinking

The Product Simply motto, "Run Your Show," is about leveraging your unique strengths and authentic problem-solving style. This doesn't mean bringing personal biases into your professional decisions without justification. Instead, it means applying your inherent curiosity and analytical skills to business problems with business logic. Your authentic strength as a PM lies in your ability to think critically and strategically, even when faced with ambiguity.

Practicing this shift in perspective—always asking "why does this make business sense?" for every decision—will elevate your interview responses and demonstrate the kind of strategic, data-informed thinking that top tech companies are looking for. It's about showing them you're ready to make choices that move the product forward, not just ones that feel familiar.
