Welcome to your interview.
The question is on your right: Architecture and Tech Stack Choice. 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.
Walk through the architecture of your most recent project and explain why you chose that specific tech stack.
