About this interview
A technical interview on Deployment Strategies, pitched at the medium level. A voice AI interviewer leads the conversation, adapts its questions to your answers, keeps you on topic, and afterward gives you honest, specific feedback on where you were strong and where to improve. Expect roughly 30 minutes.
What you'll be assessed on
Describe shadow deployment, canary releases, and A/B testing as risk-reduction patterns for model rollouts
Explain blue-green deployment and feature flags as tools for safe model transitions
Articulate how to roll back a model version safely when quality degrades in production
Discuss how to version model APIs and maintain backward compatibility for downstream consumers

A few sample questions
Just examples to set expectations - the real interview has many more and adapts to your responses.
“Before we get into specific release patterns, can you walk me through why you cannot just swap a new model version into production the same way you would deploy a new version of a stateless web service?
“Blue-green deployments give you a very fast rollback path. What are the main costs or operational downsides of maintaining two full production environments?
“How would you use contract testing to catch model API breakage before a deployment reaches production?
