Welcome to your interview.
The question is on your right: Handling Spatial Geographic Data. 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.
Explain how you would handle and structure large datasets, such as spatial or geographic data used in route planning at Railpros.
