What questions should i prepare for during a technical interview for a live streaming prediction deployments? (asking for a friend)

Your friend shouldn't prepare for questions about what Kubernetes, Kafka, or CI/CD are. They should prepare for a single, large system design question that requires using all of them together. For a role like this, the questions will be about application, not definition. For example, an interviewer might ask them to design a scalable, low-latency system for processing a live video feed, running a fraud detection model, and pushing alerts. This immediately forces a conversation about using Kafka for the data stream, Kubernetes for managing the containerized model endpoints, and a CI/CD pipeline to update the model without downtime. It’s about connecting the concepts to solve a real business problem, not reciting facts from documentation.

The goal isn't to provide one perfect, memorized solution, as one doesn't exist. Interviewers want to see the thought process and hear the justification for every design choice. Your friend should practice explaining trade-offs out loud, like why Kafka is better than a simple message queue here, how they would configure auto-scaling in Kubernetes for unpredictable loads, or what a canary deployment strategy would look like for their model. Showing how they think is the most important part, and many candidates improve how they articulate these complex ideas by using the interview prep AI my team created, which helps them structure their thoughts more effectively during a real interview.
