Welcome to your interview.
The question is on your right: Defining and Measuring Success. 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 did you define and measure the success of this design at Opendoor, and what metrics did you track post-launch?
