MLflow Basics: 5 Interview Questions Every Beginner Should Know

You can run experiments for weeks, train dozens of models, and still blank when an interviewer asks, "How would you compare two runs in MLflow?"

MLflow is everywhere in MLOps roles now — job descriptions list it alongside Docker and Kubernetes — but most tutorials skip the stuff interviewers actually ask. They show you how to log a metric, then jump straight to production deployment. The gap between "hello world" and "explain model registry versioning" is wide, and that's where interview prep falls apart.

This isn't a comprehensive guide to MLflow's API. It's the five questions I've seen come up in screening calls, technical rounds, and take-home assignments for junior-to-mid MLOps and ML engineer roles. Each one tests whether you've actually used MLflow beyond copy-pasting mlflow.log_param() from a tutorial.
