Welcome to your interview.
The question is on your right: Defining Productivity and Fit. 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 personally define productivity, and how does Superhuman fit into the modern enterprise workflow?
