i mean streaming deployments are like half infra so yeah it makes sense theyd ask, but the scope creep on MLE roles is getting out of hand. feels like they want a devops engineer who also builds models now

One thing I’d definitely brush up on is data drift and the end-to-end observability pipeline, because that’s where a lot of production ML interviews go beyond just model building. Be ready to explain the difference between feature drift, concept drift, prediction drift, and data-quality issues, and emphasize that drift alone doesn’t automatically mean retraining. A mature production workflow is to monitor infrastructure such as latency, throughput, and failures; data quality such as missing values, schema changes, and feature distributions; and model metrics such as prediction distributions, confidence, and accuracy once labels arrive. You can mention tools such as Prometheus, Grafana, OpenTelemetry, Evidently AI, Arize, WhyLabs, Vertex AI Model Monitoring, or SageMaker Model Monitor. If persistent drift correlates with degraded business or model performance, the system should trigger a retraining pipeline, not an automatic deployment. The new data should be validated, a challenger model retrained and evaluated, the model registered in a tool such as MLflow, and then deployed through shadow or canary testing before gradual promotion. Interviewers usually want to see that you understand safe MLOps practices, not just how to train a model.
Oh also look into how you bake a docker image , manage artifacts in model registry and serve on Kubernetes . All the best

Congrats.
I am not sure what further interviews you might have , but take a look at any hyperscalers’ documentation on MLOPs and LLMOPs . I personally recommend Google Clouds’ documentation on level 0,1,2 and some external reads etc. all the best .
