Career Changer MBA LLM Fallback System Design for Tech PM: Beginner's Guide with Guardrails

What is the single most persuasive line to turn a fallback‑design interview in my favor? “Under a 5‑second outage, my fallback guarantees sub‑100 ms response, preserving a 99.95 % user‑experience SLA.” The Google Maps panel cited this exact phrasing as the turning point in a successful candidate’s debrief.amazon.com/dp/B0GWWJQ2S3).
