Welcome to your interview.
The question is on your right: Multi-Player Card Game Engine. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Implement a multi-player card game engine for Affirm where a deck of cards is distributed among players, and the player with the highest score wins; extend your solution to handle a variable number of players, custom deck sizes, and dynamic winning rules.
