Estimation question

How many video game consoles are sold each year?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Structured market sizing combining installed base and console generation replacement cycles.

Clarify scope: new console unit sales globally per year, across major platforms like PlayStation, Xbox, and Nintendo Switch.
Estimate the addressable gaming population, roughly 500 million to 1 billion active console gamers globally (assumption).
Estimate replacement and new-buyer rate: consoles are typically kept 4 to 6 years, with a spike during a new console generation launch year.
Combine: roughly 15 to 20 percent of the console-owning base buys a new or replacement console in a given year outside a launch spike.
Calculate: applying that rate to an installed base of a few hundred million active consoles gives roughly 50 to 100 million units sold annually.
Sanity check: this range is broadly consistent with the multi-platform, multi-region global console market's known scale (common knowledge).

Anchors on a replacement cycle assumption, 4 to 6 years, to derive an annual turnover rate rather than guessing a flat number.
Shows the calculation clearly, applying a turnover percentage to an installed base estimate.
Notes that a new console generation launch year would significantly spike this number, showing awareness of cyclicality.

Giving a single flat guess with no installed base or replacement cycle reasoning.
Ignoring launch-year cyclicality entirely, treating every year as identical.
No shown calculation connecting the assumptions to the final number.
