Clarification -
- What is defined as fake news?
- Why does it matter?
- Impact to what? User retention? user engagement? Acquisition rate?
Let's define fake news as posts from new users who create a large amount of content and have low friend count & friend invites. Offer to define "new" & "low" if interviewer wants you to spend time there. If this is a brand new definition, start small and have human review to validate that definition is in fact reasonable.
Let us consider only US created posts that appear in the newsfeed.
Let's say the impact we prioritize is user engagement. Few metric options:
- login freq or
- total time spent on newsfeed or
- Total time spent on FB
- User activity i.e. reactions & comments
Pick one.
Check if the selected metric is co-related to how many fake news posts appear in their news feed?
Segment this by user type (new vs established)
