Welcome to your interview.
The question is on your right: Interpreting P Values in Experiments. 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 reading an A/B test result for an Instagram Reels ranking change, and the primary metric is Instagram Save. The readout reports a p-value, and the team wants to know what that number actually means, especially since the analysis used CUPED.
How would you interpret a p-value in a product experiment?
