Operations Marketplace interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Tell me about a project where you owned a measurable marketplace outcome — completion rate, supply hours, ETA, contribution per trip.
3. Tell me about a weakness, a failure, or feedback you have worked on.
4. Why marketplace operations — versus platform PM, consulting, or single-sided growth?
5. Why this mode — rideshare vs delivery vs courier vs micromobility?
6. Why the firm?
7. Walk me through the firm's product, marketplace, and unit economics in your own words.
8. How does the marketplace operations function actually drive value at a ride-share platform?

Technical concepts to master

• Supply / demand dynamics + matching engine

  Supply / demand balance + liquidity · Surge / dynamic pricing as a balancing signal · Completion rate as the master KPI · Matching engine + dispatch radius · Atomic network + cold-start dynamics

• Supply ops + driver lifecycle

  Driver acquisition + onboarding · Driver activation · Driver retention + earnings sensitivity · Supply hours + utilisation · Driver classification + regulatory exposure

• Demand ops + rider lifecycle + ETA

  Rider acquisition + first-ride conversion · Trip frequency cohorts · ETA + price experience triangle · Demand shaping + scheduled rides · Rider retention + LTV by cohort

• Incentives + unit economics + take rate

  Gross bookings + take rate + contribution per trip · Incentive efficiency + incrementality · Supply incentive mechanisms · Take rate + supply-side competitive dynamics · Rider incentive economics + first-ride payback

Practical drills

• the firm's city dashboard shows: peak-hour surge multiplier 1.8x (up from 1.3x last quarter), ETA 9 min (up from 6 min), completion rate 84% (down from 90%), supply hours -8% WoW, requests +6% WoW. Average gross bookings per trip $14, current take rate 25%, current contribution per trip $1.20. Walk through diagnosis + the first three moves with rough unit-economic math.
• the firm is launching in a new 500K-population city in 6 months. There is one incumbent rideshare competitor with ~60% share. Walk through your launch playbook.
• You have $500K to spend on driver incentives this quarter in one city. The city currently shows: supply hours -5% QoQ, peak-hour ETA 8 min (target 6 min), driver retention at 90 days 70% (target 80%). Walk through how you would design + measure the incentive + the unit-economic math.

Smart-question anchors

• Marketplace unit economics — disclosed contribution per trip, take-rate posture, growth-vs-profit trajectory
• Supply-side strategy — driver retention, incentive intensity, regulatory exposure + classification posture
• City + market mix — growth vs mature city split, geographic posture, launch playbook + recent results
• Central ops vs city ops shape — how decisions are made between central marketplace + city teams
• Matching + dispatch tech — algorithm posture, ETA prediction, batching for delivery, recent improvements
