What this question tests
Tests negotiation and unit-economics evaluation: can you quantify the trade-off of a higher commission demand against the strategic value of the partnership, not just accept or reject on gut feel.
How to approach it
- Clarify the ask: Burger King wants a higher commission rate than standard, so the evaluation is whether the incremental volume and strategic value justify a lower margin per order.
- Estimate the current economics: assume a typical commission rate and per-order profit as a baseline, then calculate margin given up at the demanded rate, clearly marked as an assumption.
- Estimate the offsetting value: a major national chain drives volume and new customer acquisition, people installing DoorDash for a trusted brand, offsetting thinner margin.
- Consider the competitive angle: if a rival like Uber Eats would take the business at that rate, DoorDash risks losing the brand's volume entirely, a bigger loss than a thinner margin.
- Propose a negotiation structure rather than binary accept or reject: a volume-tiered commission or a short trial tied to performance.
- Define the decision criteria as net incremental profit, volume times margin plus acquisition value, versus the walk-away alternative.
What a strong answer includes
- Frames this explicitly as a volume-times-margin trade-off with a clearly labeled assumption, rather than a gut-feel accept or reject.
- Names the customer-acquisition value of a trusted national brand explicitly, an often underweighted factor in this kind of negotiation.
- Considers the competitive walk-away risk, losing Burger King to a rival platform, as part of the evaluation, not just the margin math.
- Proposes a structured negotiation counter, a volume-tiered rate, instead of a binary yes or no.
Common mistakes
- Giving a flat yes or no without any quantification of the volume-versus-margin trade-off.
- Ignoring the customer-acquisition and brand-trust value a major chain like Burger King brings beyond the direct commission math.
- No consideration of the competitive walk-away risk if DoorDash refuses and a rival platform wins the partnership instead.

- How would you structure a volume-tiered commission deal concretely?
- What would you do if Burger King threatened to go exclusive with a competitor regardless of your counteroffer?
