Your question is Explaining Architecture Trade-offs Clearly. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Walk me through the architecture of a recent project you worked on. What were the hardest technical trade-offs you had to make, how did you make those decisions, and what would you change if you rebuilt it today?
