Interview Prompt
Our platform hosts millions of real-money rummy and poker games daily, and every card deal, bet, and fold is a regulated financial transaction under India's gaming laws. Our fraud team needs to analyze complete game sessions, but right now we only have raw event streams with no session context. Design a pipeline that reconstructs full game sessions and feeds our fraud and analytics systems.
Summary
Real money on the table. Reconstruct every hand.
