Interview Prompt
Your hospitality platform receives booking events from three distinct source systems, each with different delivery mechanisms, update frequencies, and data formats. All events must land in a low-latency lookup store queryable by property and date. Design the ingestion, normalization, and write strategy.
Summary
PMS, OTA, and website all think they took the reservation first.
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
