Welcome to your interview.
The question is on your right: Maintainable, Scalable Code. 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 do you ensure your code is maintainable and scalable for future developers at Integrated Data Services (IDS)?
