Estimation question

How much revenue does your favorite restaurant makes 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

Estimation combining seating capacity, turnover, and average spend into a defensible revenue figure.

Pick a concrete restaurant type to ground the estimate, for example a mid-size sit-down restaurant with about 40 seats.
Estimate table turnover, assuming each seat turns over roughly 2 times at lunch and 2 times at dinner, about 4 turns daily.
Estimate average spend per customer, assuming around 25 dollars including drinks, a reasonable mid-tier assumption.
Calculate daily revenue: 40 seats times 4 turns times 25 dollars equals 4,000 dollars per day.
Annualize: 4,000 dollars times 365 days gives roughly 1.46 million dollars, adjusted down slightly for slower weekdays to around 1.2 to 1.4 million.
Sanity check against typical restaurant industry revenue benchmarks for a similarly sized establishment.

Builds the estimate from concrete, checkable inputs, seats, turnover, and spend, instead of guessing a lump revenue figure.
States each assumption explicitly and adjusts for real-world variance, weekday versus weekend.
Sanity checks the result against known industry norms for a similarly sized restaurant.
Presents a reasoned range instead of one falsely precise number.
