Welcome to your interview.
The question is on your right: Interactive Ad Formats Across Devices. 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.
How do you approach designing custom, interactive ad formats that must perform well across different mobile operating systems and screen sizes?
