Welcome to your interview.
The question is on your right: Scalable and Maintainable Solution Execution. 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.
You're designing a new solution that is expected to grow over time, and you want to avoid creating something that becomes expensive to operate or hard to change after launch.
How do you ensure that your solutions are scalable and maintainable?
