Interview Prompt
We host millions of real-money rummy and poker games a day in India, and every deal, bet and fold arrives as a raw event stream with no session context. A player who has sent nothing for two minutes has left the table. Design the pipeline that reconstructs complete game sessions and feeds our fraud and analytics systems.
Summary
Real money on the table. Reconstruct every hand.
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
