Welcome to your interview.
The question is on your right: Late-Arriving Data in Spark Airflow. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you handle late-arriving data in a daily batch processing pipeline built with Apache Spark and Airflow for Reddit?
