Your question is Design API Gateway Pipeline Layer. 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).
You're defining the front door for a new platform and want a clean way to control how requests enter downstream services. You need a design that handles common gateway concerns before traffic reaches internal APIs.
How do you design an API gateway layer to handle rate limiting, authentication, and request routing at scale?
