Interview Prompt
We're a telecom provider building a new data warehouse. We need to model our network infrastructure: towers, switches, fiber links, and the connections between them. We also need to track outages and capacity utilization. Can you design this?
Summary
One device goes down. The ripple keeps going.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Draw your data model on the schema canvas: tables, keys and relationships
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
