Top 3 Proof of delivery Interview Questions
Browse 3 real-world technical and behavioral interview questions about Proof of delivery. Review scenarios, edge cases, and architectural best practices.
How do you offer a delivery slot at checkout that the network can honour?
A slot shown at checkout has to be a reservation against remaining route capacity measured in minutes rather than a count of orders, and the flow behind it needs an offline-tolerant driver app, proof of delivery sized to the risk, and a designed path for the attempt that fails.
A driver spends part of the day with no mobile signal. How do you design the app so the round still works?
Treat the device as a first-class writer rather than a cache: it generates its own identifiers, records two timestamps per event, and queues durably until the network returns. Every submission carries an idempotency key because retries are certain, and genuine contradictions go to a human.
The driver arrives and nobody is home. Walk me through what happens next and what your system has to get right.
A failed delivery attempt in last-mile logistics is a structured event, not just failed status. The system must capture the allowed outcome, proof, attempt budget, customer notification and next custody location so redelivery, pickup or return can proceed safely.
