Alpha-Beta Pruning
Alpha-Beta Pruning is a technique used in computer programs that play games or make strategic decisions. Think of it like a smart shortcut that helps computers quickly evaluate different moves or choices without having to look at every single possibility. It's commonly used in games like chess, checkers, or Go, where the computer needs to think several moves ahead. This method helps make AI programs run faster and more efficiently, which is important when creating game AI or decision-making systems. When you see this on a resume, it shows that the candidate understands how to make AI systems work smarter, not harder.

Example Interview Questions
Senior Level Questions
Q: How would you optimize Alpha-Beta Pruning for a commercial game engine?
Expected Answer: A strong candidate should explain how they would make the algorithm more efficient by mentioning move ordering, memory management, and parallel processing in simple terms. They should also discuss real-world trade-offs between speed and decision quality.
Q: Can you explain how you would implement Alpha-Beta Pruning in a multi-player game?
Expected Answer: The candidate should be able to explain how they would adapt the technique for more than two players, discussing challenges and solutions in clear, non-technical terms.
Mid Level Questions
Q: What are the main benefits of using Alpha-Beta Pruning in game AI?
Expected Answer: They should explain that it helps computers make decisions faster by eliminating obviously bad choices early, using practical examples like chess or similar games.
Q: How would you explain Alpha-Beta Pruning to a non-technical stakeholder?
Expected Answer: Look for candidates who can use simple analogies and clear explanations without technical jargon, showing they truly understand the concept.
Junior Level Questions
Q: What is the basic concept of Alpha-Beta Pruning?
Expected Answer: They should be able to explain that it's a method to help computers make better decisions faster by not wasting time on moves that won't be chosen anyway.
Q: Where have you used Alpha-Beta Pruning in your projects?
Expected Answer: Look for practical experience, even if just in academic projects or simple games, showing they understand how to apply the concept.
