Real interview territory, not generic definitions. The AI draws on these areas and pushes into the sub-topics where you are weakest.
These are the kinds of scenario-based questions Joshua asks. In a live session they adapt to your answers and your target role.
How do you detect that a model in production has started to degrade, before users complain?
Explain training/serving skew and how a feature store with point-in-time joins prevents it.
Design a safe rollout for a new model version where you cannot fully trust offline metrics.
What does reproducibility actually require in an ML training pipeline?
Batch scoring vs online inference: how do you decide, and what changes operationally?
Both, plus dedicated MLOps and ML platform roles. The emphasis is productionization, not model theory.
Yes. Data drift, concept drift, ground-truth lag and performance monitoring are core topics.
It focuses on shipping, serving, and operating models reliably, rather than modeling and statistics.
