Welcome to your interview.
The question is on your right: Counter a Free-Delivery Promotion. 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.
A local competitor has launched a promotion offering free delivery. How would you analyze the impact on our local market share, and what data points would you use to formulate a counter-strategy?
