Your question is Driver Supply vs Rider Demand. Take a moment with it on the right.

Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Problem

Scenario

You are advising a two-sided mobility marketplace where leadership has to choose where to focus near-term product investment. The business can ship features on the driver side, such as earnings visibility, destination filters, or onboarding improvements, or on the rider side, such as discovery, promotions, or trip conversion improvements. The right answer depends on marketplace health in each city, because pushing rider demand into an already constrained market can worsen ETAs and cancellations, while pushing driver supply into a weak demand market can hurt utilization and earnings.

Question

Should we prioritize features that increase driver supply or rider demand right now? How would you decide?

Representative Context

City A: request volume +12% month over month, ETA up from 4.8 to 6.5 minutes, driver cancellation 9%
City B: ETA stable at 4.5 minutes, rider conversion flat, driver utilization healthy
City C: active drivers +10% year over year, trips per driver hour -14%, 90-day driver retention down from 68% to 59%

What This Tests

Can you identify the binding marketplace constraint?

Can you reason through two-sided network effects?

Can you compare supply and demand investments using economics, not intuition?

Can you segment by city and daypart instead of giving one global answer?
