Prepare a simple system diagram of a project you worked on and discuss it with an engineer.
Asked in the Onsite: project focused stage. Choose an ML project you know well enough to explain implementation decisions, data flow, model inference, and operational tradeoffs. Keep the diagram simple and focus on the parts you personally designed or implemented.
Be prepared to explain the system end to end, including how data was collected, models were trained and served, how performance was evaluated, and what happened when components failed. Clarify assumptions where your project did not use a particular ML-system component.
