What this question tests
Aggressive growth-focused product design, requiring the candidate to identify a lever big enough to plausibly double a customer base, not incremental tweaks.
How to approach it
- Clarify what 'double the customer base' means for a hyperlocal delivery service, new monthly active users versus new cities served.
- Identify Dunzo's core constraint at that scale: likely geographic coverage and delivery-partner supply capping growth in served cities, or low awareness outside its core markets.
- Propose a growth lever proportional to the ambition, e.g. a hyperlocal 'anything delivery' expansion into adjacent underserved categories (medicines, groceries) paired with an aggressive delivery-partner recruitment push in new neighborhoods.
- Address the supply-demand balance explicitly: growing demand without growing delivery-partner supply just increases wait times and churns new users, so the plan must grow both together.
- Define success as net new monthly active users and delivery-partner utilization rate as a guardrail against over-promising delivery times.
What a strong answer includes
- Picks a lever big enough to plausibly move a metric by 2x, not an incremental UX tweak.
- Explicitly addresses the two-sided supply-demand balance, a hyperlocal delivery service's core operating constraint.
- States a concrete new-user acquisition metric alongside a supply-health guardrail.
Common mistakes
- Proposing small UX polish (better search, faster checkout) that couldn't plausibly double a customer base.
- Growing demand-side marketing without addressing delivery-partner supply, leading to bad experiences and churn.
Likely follow-up questions
- How would you sequence expansion into new cities versus new categories in existing cities?
- What would make you believe this lever can realistically 2x the base versus a smaller, more defensible number?
