Introduction

Welcome to this step-by-step guide for aspiring product managers (PMs), particularly those eyeing positions within FAANG companies. This section delves into the intricacies of a common product interview question you might encounter and emphasizes the importance of structured frameworks for crafting compelling responses. The question we’ll be analyzing today is: “Design an elevator for the blind?”

Detailed Guide on Framework Application

We will employ the CIRCLES Method™, a well-regarded framework introduced in ‘Decode and Conquer: Answers to Product Management Interviews,’ to dissect our question.

Comprehend the Situation

Begin by clarifying any ambiguities in the question. Confirm that your understanding of “blind” includes all levels of visual impairment and that the end goal is an accessible and user-friendly elevator experience for this demographic.

Identify the Customer

Ascertain who will use your product. Besides individuals who are completely blind, consider those with partial sight and how different features might benefit or hinder their experience. Empathy is key.

Report the Customer’s Needs

Discuss the primary needs of visually impaired users in the context of using an elevator: safety, independence, and ease of use. Also consider secondary needs such as comfort and confidence while using the product.

Cut Through Prioritization

Prioritize the needs you’ve identified. Safety is non-negotiable, thus it would take precedence. Independence might be next, followed by ease of use. Explain your rationale for this hierarchy.

List Solutions

Offer a range of solutions for each prioritized need. For safety, you might suggest voice-activated systems or braille buttons. For independence, consider providing audio feedback for each floor or a specialized app that aids elevator use.

Evaluate Trade-offs

Consider the pros and cons of each proposed solution. An app, for instance, offers cutting-edge accessibility but may exclude users without smartphones. Braille buttons are inclusive but can be limiting without audio cues for floors.

Summarize Your Recommendation

Conclude with a clear and concise final recommendation that balances the needs and limitations discussed. The recommended solution should be inclusive and practical, possibly a combination of braille buttons, voice guidance, and app integration for advanced features.

Throughout this, hypothesize with realistic assumptions. If the average elevator cabin size is about 6 to 8 feet across, ensure your solution fits within this constraint.

Communication Tips

Be clear, concise, and confident in your presentation. Anchor your statements with the customer’s needs and use empathetic language to show your understanding of the user’s experience. Maintain a structured narrative that guides your interviewer through your thought process.

Conclusion

The key takeaway is the importance of the structured response—CIRCLES Method™ in this case—aiding the interview candidate to navigate complex product questions effectively. As a final note, practice using these frameworks before your interviews to ensure your answers are polished and impactful.
