Interview Prompt
On our short-video platform the catalog is small and views pile up fast, so the catalog travels to the views rather than the views moving for the lookup. Pair each view with its video's creator and report how many seconds each creator's videos were watched and how many views they drew, keeping the creators above 1000 seconds of watch time.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write and run your Spark code against the tables
- Answer the interviewer's follow-up questions, then get a hire or no-hire decision
