Interview Prompt
Creators keep telling the support team their link stats lag, and the analytics API's date-range reports crawl, at about 200 million redirects a day with viral links spiking traffic. Design the pipeline that carries every click event both to the nightly totals behind those reports and to the creators' per-link last-hour dashboard.
Summary
Billions of clicks. One tiny code. Two very different clocks.
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
