Trash Can Redesign: Generate and Prioritize Ten User-Driven Improvements

Quick Overview

A product design interview prompt that asks a PM candidate to reinvent the household trash can by proposing ten new features. It tests choosing a target user, tracing pain points through the bin's everyday use, and prioritizing ideas against cost, reliability and measurable success.

Interview Round: Other

Reinvent the everyday trash can. Propose ten new features that would make it meaningfully better for the people who use it: decide who you are designing for, tie each feature to a real frustration, and say which ones you would build first. ```hint Walk through a bin's week Before brainstorming, follow one household's bin from the first item thrown in until collection day. Features that fix a specific moment along that path are stronger than a list of gadgets. ``` ### Clarifying Questions - Is this a kitchen bin at home, an office bin or a public street bin, or is the setting my choice? - Can the redesign include sensors, batteries and an app, or should it stay an unpowered, low-cost product? - Is there a target price, or am I free to design a premium bin? - Do all ten features need to fit one model, or can they be spread across a basic and an upgraded version? ### What a Strong Answer Covers - A deliberate choice of setting and user segment before any features are proposed - Pain points traced through the bin's whole lifecycle, not only the moment something is thrown away - Ten distinct features, each tied to a pain point, mixing simple mechanical fixes with connected ideas - A prioritization that weighs user value against cost, reliability and power needs - How success would be measured, and the risks of the more ambitious ideas ### Follow-up Questions - If the bin had to sell at roughly the price of an ordinary one, which three features would you keep, and why? - How would the design change for public street bins, where the buyer is a city rather than the person using the bin? - How would you test demand for the connected features before committing to manufacturing?

Reinvent the everyday trash can. Propose ten new features that would make it meaningfully better for the people who use it: decide who you are designing for, tie each feature to a real frustration, and say which ones you would build first.

Clarifying Questions Guidance

  • Is this a kitchen bin at home, an office bin or a public street bin, or is the setting my choice?
  • Can the redesign include sensors, batteries and an app, or should it stay an unpowered, low-cost product?
  • Is there a target price, or am I free to design a premium bin?
  • Do all ten features need to fit one model, or can they be spread across a basic and an upgraded version?

What a Strong Answer Covers Guidance

  • A deliberate choice of setting and user segment before any features are proposed
  • Pain points traced through the bin's whole lifecycle, not only the moment something is thrown away
  • Ten distinct features, each tied to a pain point, mixing simple mechanical fixes with connected ideas
  • A prioritization that weighs user value against cost, reliability and power needs
  • How success would be measured, and the risks of the more ambitious ideas

Follow-up Questions Guidance

  • If the bin had to sell at roughly the price of an ordinary one, which three features would you keep, and why?
  • How would the design change for public street bins, where the buyer is a city rather than the person using the bin?
  • How would you test demand for the connected features before committing to manufacturing?
