Estimate the number of daily food orders on Swiggy in Bangalore.

Framework
top-down + bottom-up cross-check
Model answer
Top-down: 13M Bangalore population × 25% smartphone-active urban working adults × 20% weekly order rate ÷ 7 days ≈ 90K daily orders. State assumptions out loud, then sanity-check with a bottom-up count of restaurants × avg orders/restaurant.
What great candidates actually do
- Announce the approach before you start calculating.
- Segment the market — office lunch, weekend dinner, late-night snack behave differently.
- Do a second estimate from a different angle; if they're 3x apart, one is wrong.
Traps to avoid
- Naming the solution before the problem — always restate the goal in one sentence first.
- Answering without structure — pick a framework out loud, then execute it.
- Skipping the trade-off — every strong answer names what you would NOT do and why.
