Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What is your experience with real-time data processing frameworks?
Discuss the frameworks you have used, such as Apache Kafka, Apache Spark Structured Streaming, or Apache Flink. Explain how you handled event ingestion, stateful transformations, delivery guarantees, schema evolution, backpressure, checkpointing, failure recovery, and operational monitoring. Include a concise architecture sketch and representative code or configuration from a production pipeline.
