Interview Prompt
How would you keep shipment state accurate when tracking scans from warehouses, vehicles and delivery points across 18,000 pin codes in India arrive out of order, so a delivery scan can land before the origin hub's departure scan? The ops team also has to catch parcels moving in the wrong direction.
Summary
Out for delivery. Delivered. Except the events arrived backwards.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your pipeline on the design canvas: sources, transforms, storage and checks
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
