Welcome to your interview.
The question is on your right: Defend Architecture Decisions Clearly. 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 discussing a technical architecture you designed for a networked system and want to present it in a way that shows sound judgment, not just technical depth. The goal is to explain why you chose this design, show that you considered credible alternatives, and make the business and operational impact legible to both technical and non-technical stakeholders.
How would you explain your architecture decisions, critique alternatives, and quantify impact in an interview?
