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
