Estimation question

Estimate AWS's total annual revenue.

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 estimation using a top-down market-sizing approach with defensible assumptions.

Clarify approach: use a top-down method, estimating total global cloud infrastructure spend and AWS's market share, rather than bottom-up.
Estimate total global cloud infrastructure market size, using an assumed figure grounded in general market awareness.
Estimate AWS's market share of that total, assumed to be the largest single player at roughly 30 to 35%.
Multiply market size by share to get an estimated AWS revenue figure.
Sanity check the result against general awareness of AWS being a large, profitable division within a larger company.
State the final estimate as a range, with the market size and share assumptions called out explicitly.

Chooses a market-share top-down method deliberately, explaining why it's more tractable than bottom-up for a company this size.
States both the market size and share assumptions explicitly as assumptions, not facts.
Shows the full multiplication clearly so the interviewer can challenge either input.
Delivers a range and acknowledges the estimate's sensitivity to the market-share assumption.

Attempting a bottom-up estimate (servers, customers) when a top-down market-share approach is far more tractable here.
Presenting a single precise-looking number with no stated assumptions.
