Interview Prompt
Our TV and digital ad measurement pipelines are completely separate: TV exposure arrives as second-level logs from set-top boxes, and digital arrives as impression logs from connected apps. Design a pipeline that combines them into cross-platform audience metrics for campaigns that ran on both broadcast TV and connected apps.
Summary
TV and digital. Same viewer, two measurement worlds.
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
