Estimate how many deal seekers could use Kindle weekly in one major market

Problem Statement Description

Product context: Amazon is a commerce, logistics, media, devices, and cloud company; its products include Marketplace, Prime, Prime Video, Alexa devices, ads, fulfillment, and AWS.

Estimate the number of deal-seeking consumers who could use Kindle in a typical week within one major market. For this problem, “deal seekers” should be treated as price-sensitive readers or Amazon shoppers who are motivated by discounts, free titles, limited-time offers, bundled subscriptions, or low-cost access to books and reading content.

You should frame the market clearly, such as the U.S., U.K., or India, and define whether you are estimating weekly active Kindle readers, potential users reachable through Amazon’s ecosystem, or people who engage with Kindle specifically because of deals. The estimate should reflect Kindle as both a device and app-based reading experience, not only dedicated e-reader hardware.

The experience should consider:

- The exact market and population base being estimated

- The unit of measurement: weekly users, weekly active deal-driven users, or potential weekly users

- How to define “deal seeker” in the context of Kindle and Amazon’s broader shopping behavior

- Relevant population filters, such as internet access, Amazon account penetration, reading habits, and digital book adoption

- Kindle access paths, including Kindle devices, mobile apps, tablets, and web reading

- Deal-driven triggers such as Kindle Daily Deals, free books, Prime Reading, Kindle Unlimited promotions, seasonal sales, and price alerts

- Frequency assumptions for reading, deal discovery, and weekly engagement

- Sensitivity checks around adoption rates, market maturity, and overlap with existing Amazon customers

The goal is to produce a structured, defensible estimate with clear assumptions, logical segmentation, and sanity checks. The interviewer is looking for how you scope ambiguity, size a user segment, reason from available proxies, and communicate uncertainty rather than for a single precise number.
