Have you taken a model from development to deployment before?

🎯 What Interviewers Are Looking For
  • End-to-end ML experience (not just training models in notebooks)
  • Understanding of production ML challenges
  • DevOps/MLOps awareness
  • Real-world deployment experience vs academic projects
📋 STAR Framework Guide

Structure your answer using this framework:

S - Situation

What model did you deploy? What was the use case?

T - Task

What were the deployment requirements (latency, scale, reliability)?

A - Action

Walk through your deployment process: infrastructure, serving, monitoring

R - Result

Did it work in production? What did you learn about deployment?

💬 Example Answer
⚠️ Pitfalls to Avoid
  • Saying you "deployed" but only saved a pickle file
  • Only talking about training without discussing serving/infrastructure
  • Not understanding the difference between development and production
  • Claiming enterprise-level deployment experience when you haven't
  • Focusing only on the model without discussing the system around it
  • Not acknowledging what you haven't done yet
💡 Pro Tips
  • Be specific about your deployment stack (Docker, Flask/FastAPI, cloud platform)
  • Emphasize what you learned, even if deployment was simple
  • Show you understand production concerns: latency, monitoring, errors, scale, reliability
  • Discuss observability: metrics, logging, tracing (the three pillars)
  • Mention reliability patterns: circuit breakers, retries, graceful degradation
  • If you haven't deployed: talk about what you would do and why
  • Mention challenges you faced and how you solved them
  • Acknowledge limitations honestly: "This was simpler than enterprise systems, but..."
  • Connect to role: "I want to learn more advanced MLOps practices like X and Y"
  • Discuss deployment strategies: blue-green, canary, rolling updates
🔄 Common Follow-up Questions
  • What deployment platform did you use and why?
  • How did you handle model versioning?
  • What monitoring metrics do you track in production?
  • Have you implemented A/B testing for models?
  • How do you handle model updates without downtime?
  • What's your strategy for handling production errors?
  • Have you worked with Kubernetes or model serving frameworks like TensorFlow Serving?
  • How do you handle graceful degradation when the model is slow or unavailable?
  • What's your approach to distributed tracing across microservices?
  • How do you implement auto-scaling for ML workloads?
  • What reliability patterns have you used (circuit breakers, retries)?
