Welcome to your interview.
The question is on your right: Diagnose Website Conversion Rate Drop. 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 the marketing analytics team for a B2B design software website. Over the last 10 days, the website conversion rate from visit to trial signup fell from 3.8% to 2.9%, while total sessions stayed roughly flat at about 420,000 per week. The drop started shortly after a homepage update and a paid media budget shift, and leadership is worried because trial starts feed the pipeline for products like AutoCAD and Fusion. The weekly business review is coming up, and you need a clear diagnosis.
How would you analyze a sudden drop in website conversion rates?
