Welcome to your interview.
The question is on your right: Design a URL Shortening Service. 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 are designing a URL shortening service for a consumer and business platform. Users create short links, share them across channels, and expect the service to route clicks correctly while supporting analytics and abuse detection.
How would you design a URL shortening service like Bitly?
