Name three products you like and know well. Pick one, explain why you like it, and describe how you would adapt it for a new market segment. ```hint Earn the why, then change the user Pin down what the product does better than its alternatives, and for whom. Then ask which of those strengths would still matter, and which would get in the way, for a group it does not serve well today. ``` ### Clarifying Questions - Should the three products come from different categories, or is it fine if all three are software? - Must the new segment be one the product does not serve at all today, or can it be an under-served group within its current market? - Am I adapting it as the product's own PM, with its brand, data and infrastructure available? - Does a new country count as a new segment, or should I focus on a new type of user? ### What a Strong Answer Covers - A varied list of three products, with one the candidate can discuss in depth - A reason for liking the product that names a specific user, the problem solved, and the design or business choices that set it apart from alternatives - A justified choice of new segment, showing how its needs, barriers and context differ from current users - Concrete adaptations prioritized by impact and effort, plus what deliberately stays unchanged - Success metrics, a way to reach the segment, and the risks of the adaptation, including diluting the product for core users ### Follow-up Questions - Which weakness of the product would you fix first for its current users, and why? - How would you test demand in the new segment before building most of the adaptations? - If the tailored version starts competing for resources with core users, how do you decide between a separate product and a mode inside the existing one?

Name three products you like and know well. Pick one, explain why you like it, and describe how you would adapt it for a new market segment.

Clarifying Questions Guidance

  • Should the three products come from different categories, or is it fine if all three are software?
  • Must the new segment be one the product does not serve at all today, or can it be an under-served group within its current market?
  • Am I adapting it as the product's own PM, with its brand, data and infrastructure available?
  • Does a new country count as a new segment, or should I focus on a new type of user?

What a Strong Answer Covers Guidance

  • A varied list of three products, with one the candidate can discuss in depth
  • A reason for liking the product that names a specific user, the problem solved, and the design or business choices that set it apart from alternatives
  • A justified choice of new segment, showing how its needs, barriers and context differ from current users
  • Concrete adaptations prioritized by impact and effort, plus what deliberately stays unchanged
  • Success metrics, a way to reach the segment, and the risks of the adaptation, including diluting the product for core users

Follow-up Questions Guidance

  • Which weakness of the product would you fix first for its current users, and why?
  • How would you test demand in the new segment before building most of the adaptations?
  • If the tailored version starts competing for resources with core users, how do you decide between a separate product and a mode inside the existing one?
