Interview Prompt
A daily clickstream lands as one giant Parquet file in S3. Analysts only ever query a single day at a time but every query scans the whole table. Lay out the storage so a one-day query reads one day of data.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your pipeline design solution with real code execution
- Get instant feedback and a hire/no-hire decision
