Most candidates think a K-factor below 1 means referral has failed. It hasn't, and knowing why is exactly the kind of nuance that separates a strong answer from a memorized one.
This guide covers all 8 referral metrics you need, NPS, Viral Coefficient (K-factor), Referral Rate, plus 5 deeper ones (CSAT, Word-of-Mouth Coefficient, Share Rate, Invite Acceptance Rate, Advocacy Rate) that show real fluency in how growth actually spreads.
Each metric gets 2 full pages: a clear explanation with a worked example, followed by 3 real interview questions with a weak answer and a strong answer side by side.
