MLOps Engineer: 8-Week Prep Path

Reading time: ~45 min | Interview relevance: Critical | Roles: MLOps Engineer, ML Platform Engineer, ML Infrastructure Engineer, ML DevOps

The Real Interview Moment

The interviewer pulls up a whiteboard and says: "Our data scientists push models to production using Jupyter notebooks and SCP. Retraining is manual. There is no monitoring. There are three models in production and twelve more in development. Design the ML platform we need."

This is the MLOps interview in a nutshell. You are not being asked to build a model -- you are being asked to build the entire ecosystem that makes models reliable, reproducible, and scalable. The MLOps Engineer is the person who turns a data scientist's prototype into a production system that serves millions of users without breaking at 3 AM.

It is a role that demands extraordinary breadth. You need to understand enough ML to know what you are operationalizing, enough DevOps to build the infrastructure, enough data engineering to manage the pipelines, and enough software engineering to make it all maintainable.

This 8-week plan covers it all.

Role Overview

What MLOps Engineers Do

MLOps Engineers build and maintain the infrastructure that makes ML work in production. They:

  • Design and operate ML training and serving pipelines
  • Build CI/CD systems for model development and deployment
  • Implement model monitoring, alerting, and automated retraining
  • Manage feature stores, model registries, and experiment tracking
  • Optimize compute costs and resource utilization
  • Ensure reproducibility, compliance, and governance of ML systems
