Welcome to your interview.
The question is on your right: Investigate User Engagement Decline. 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 supporting a digital product team that has seen a meaningful drop in user engagement over the past month. Weekly engaged users fell from 420,000 to 357,000, a 15% decline, and average sessions per active user dropped from 4.8 to 4.1 over the same period. The decline started shortly after a homepage update and a new lifecycle email campaign launch. Leadership wants to know whether this is a measurement issue, a product issue, or a shift in user behavior.
Given a drop in user engagement, how would you investigate and address this issue?
