Should a Food-Delivery App Expand into Groceries?

What interviewers evaluate

• Do you size the opportunity and note where the economics differ from restaurants?
• Do you analyze which existing assets transfer to the new category - and which don't?
• Do you segment the market (weekly stock-up vs convenience basket) and pick an entry wedge?
• Do you consider the operating model options (marketplace partner vs dark stores)?
• Do you land on a recommendation with explicit success gates and guardrails?

A framework to structure your answer

1. Frame - what goal does expansion serve (GMV growth, order frequency, courier utilization)? Restate it.
2. Size the prize - grocery TAM vs restaurant, online penetration trajectory, purchase frequency.
3. Asset-transfer analysis - what carries over (app, couriers, habit) vs what doesn't (picking labor, inventory accuracy, thin margins, incumbents).
4. Segment & wedge - split the market (big stock-up vs convenience top-up) and pick the segment your assets actually serve.
5. Operating model - partner-supplied marketplace vs dark stores vs pick-in-store; sequence from low-risk to capital-intensive.
6. Recommend with gates - pilot scope, the metrics that green-light expansion, and a hard guardrail on the core business.

Try structuring your own answer first, then reveal a strong worked example.

Common variants

• Should a ride-share company enter food delivery?
• Should an e-commerce marketplace launch a subscription service?
• Your CEO wants to enter an adjacent market a competitor owns. Evaluate it.

Pitfalls to avoid

• Treating it as pure TAM math without asking whether your assets transfer.
• Missing the structural differences (picking labor, inventory accuracy) that break the economics.
• Entering the incumbent's strongest segment (weekly stock-up) instead of finding a wedge.
• Jumping to capital-intensive dark stores before validating with a partner model.
• No success gates or core-business guardrail - expansion that quietly degrades the main product.

Likely follow-ups

• The pilot shows great order frequency but negative contribution margin. Continue?
• A dedicated grocery competitor raises a war chest. Does that change your sequencing?
• When would dark stores become the right call?
