1. 090If you had infinite time and money, what invention would you make?Brainteasers and estimationCoresuperdayDED.E. ShawConsulting · New York · 2026

   Say this

   Pick one specific thing, explain the problem it solves, and then reason about it like an analyst: who benefits, what it would cost, what would be hard, and what could go wrong. The invention is a prompt; the thinking is what is being marked.

   Then walk it

   1. Specificity beats ambition. 'Cure all disease' is a non-answer. Something like a cheap, accurate soil-nutrient sensor that tells a smallholder farmer exactly what to apply, in the local language, from a phone, is answerable and testable.
   2. Then the problem size, with a rough number. Roughly a hundred million-plus smallholdings in India, most fertilising by habit rather than measurement, which wastes input cost and damages yields. That frames the value without pretending to precision.
   3. Then the mechanism and the hard part, because interviewers listen for whether you can identify the real constraint. The sensor is not the hard part; distribution, calibration across soil types and getting the recommendation trusted are.
   4. Then the economics: what it would have to cost per unit to be adopted, who pays, and whether the value is captured through hardware, subscription or through the input supplier.
   5. Then the second-order effects, which is where you can be genuinely interesting: it shifts bargaining power toward farmers, changes fertiliser demand mix, and has an environmental effect through runoff. Good answers hold both the upside and the unintended consequence.
   6. Keep it to two minutes and show some actual enthusiasm. This question is also a personality screen: they want to know whether you think about anything outside a spreadsheet.

   Where candidates lose it

   Giving a grand abstraction, or a joke answer. The point is structured curiosity: one specific invention, the problem, the hard constraint, the economics, and an unintended consequence. And do not choose something you cannot discuss for three minutes.

   Expect next

   • What would be the hardest part to actually build?
   • How would you fund it if money were not infinite?
   • What would be the unintended consequence?
