Model Deployment
Model Deployment is the process of making data science projects available for actual business use. Think of it like taking a recipe from the test kitchen to a real restaurant. Data scientists create smart computer programs (called models) that can make predictions or analyze data, and Model Deployment is about getting these programs to work reliably in the real world where people can use them. This might mean putting them on company servers, cloud platforms, or making them part of existing business software. It's similar to launching a new product - you need to make sure it works properly, can handle many users, and delivers consistent results.

Senior Level Questions
Q: How would you handle scaling a model deployment for millions of users?
Expected Answer: Should discuss experience with cloud platforms, load balancing, monitoring system performance, and strategies for handling high traffic while maintaining quick response times. They should mention real examples of large-scale deployments they've managed.
Q: How do you ensure deployed models maintain their accuracy over time?
Expected Answer: Should explain monitoring practices, retraining strategies, and how they track model performance in production. Should mention setting up alerts for performance drops and having backup plans ready.
Mid Level Questions
Q: What steps do you take to deploy a model into production?
Expected Answer: Should describe the process of testing the model, preparing it for deployment, setting up the necessary infrastructure, and implementing basic monitoring. Should mention version control and documentation.
Q: How do you handle errors in deployed models?
Expected Answer: Should explain basic error handling, logging practices, monitoring systems, and how they would troubleshoot common deployment issues. Should mention experience with debugging tools.
Junior Level Questions
Q: What's the difference between testing a model and deploying it?
Expected Answer: Should understand that testing happens in a controlled environment while deployment means putting the model in real-world use. Should mention basic considerations like speed and reliability.
Q: What tools have you used for model deployment?
Expected Answer: Should be familiar with at least one common deployment platform or tool, and understand basic concepts of putting a model into production use.
