Summary

Interviewed for a bizops role at DoorDash, got hit with a classic market growth allocation case. Pretty open-ended, which I wasn't fully prepared for.

Q1

You have $1 million to spend on growing market share in a city. How would you allocate it?

I went straight to supply-side (more drivers) without pausing to ask which city or what the current market position even was.

Suggested Approach

Start by clarifying the goal and constraints, then segment the city market to identify the highest-leverage opportunities. Allocate the $1M across a balanced portfolio of initiatives—such as local partnerships, targeted promotions, and operational improvements—with clear metrics and a test-and-learn approach.

Pro tip: Frame your answer around unit economics and ROI: show that you'd invest where customer acquisition cost is lowest and lifetime value is highest, and emphasize the importance of measuring incrementality to avoid wasting budget on users who would have converted anyway.

1. Clarify Objectives and Constraints

Ask clarifying questions to understand the specific market, current market share, competitive landscape, and time horizon. Confirm whether the goal is short-term share growth or sustainable long-term presence.

2. Segment the Market

Divide the city into meaningful segments—by neighborhood, demographics, merchant density, or order frequency—to identify where the biggest opportunities and gaps exist.

3. Prioritize High-Impact Initiatives

Evaluate potential initiatives (e.g., merchant acquisition, consumer promotions, delivery logistics, partnerships) based on expected ROI, speed to impact, and alignment with DoorDash's strengths.

4. Allocate Budget with a Portfolio Approach

Distribute the $1M across selected initiatives, balancing quick wins and long-term bets. For example, 40% to merchant acquisition, 30% to consumer incentives, 20% to operational improvements, 10% to testing.

5. Define Metrics and Iterate

Establish clear KPIs (e.g., market share, CAC, order frequency, retention) and set up a test-and-learn framework to reallocate funds based on performance.

Key Points to Mention

  • Unit economics: CAC, LTV, payback period
  • Incrementality testing to measure true impact of spend
  • Local merchant partnerships and exclusive offerings
  • Targeted promotions for high-value customer segments
  • Operational efficiency: delivery times, Dasher supply
  • Competitive response and defensibility
